The pilot gas igniter should operate continuously, since its main function is to ignite the main burner when opening the water tap. This little light is also known as a wick. Fire is created as a result of the combustion of the air-fuel mixture. Physically, the igniter should heat up the thermocouple and reach the main burner. If the pilot light goes out, the gas water heater system will be forced to shut off the gas supply in order to prevent it from further accumulating.

Why does the igniter of a gas column go out:

.   Geyser wick clogged with dust;
  . Air flow from the outside (flame separation);
  . Lack of traction in the chimney;
  . Thrust control sensors faulty;
  . Worn or burned thermocouple;
  . Bad contact between the sensor and the control unit;
  . Ionization sensor out of range of the flame.

The most common reason why a pilot light goes out is a thermocouple malfunction. The thermocouple provides an element of the safety device intended to shut off the gas flow during unstable operation of the gas column. When the pilot light goes out, the thermocouple detects a lack of heat due to the lack of fire and turns off the gas. However, if the thermocouple burned and its tip became loose from prolonged exposure to fire, then it becomes the reason why the pilot light goes out.

However, if the thermocouple burned and its tip became loose from prolonged exposure to fire, then it becomes the reason why the pilot light goes out. Another problem is that the gas nozzle openings on the igniter have a small diameter and can become clogged with debris and dust, thus preventing normal gas burning on the igniter and, as a result, insufficient heating of the thermocouple occurs.

Outgoing air flows from the outside can blow the pilot burner. Downward airflows usually occur if the unit is ventilated improperly. Be careful whengas heater repair   Do not confuse this phenomenon with the lack of traction.

Geysers have solenoid valves that belong to the gas control system. If the ventilation system is faulty and carbon monoxide enters the room, the solenoid valve will shut off the gas supply and the pilot light will go out.

The black smoke around the ignition site and on the heat exchanger itself is another problem, why the igniter is extinguished. This soot appears from incomplete combustion of gas. The accumulation of soot on the heat exchanger can create big problems with the ventilation of air and cause the pilot light to go out during operation.

Signs of malfunctioning igniter

Pay attention to the color of the pilot light. It shows how well and correctly the gas burns. A wick that effectively burns natural gas burns with a blue flame. The color of the blue flame should be at least 90% with small red dots and a slightly yellow tip. Orange or mostly yellow color indicates to us problems with the pilot burner, which can lead to an emergency stop of the column.

Why igniter smokes? If the ratio of air and fuel becomes less than the standard values, the color of the flame takes on a yellow color and the igniter starts to smoke and sluggishly burn. This leads to insufficient heating of the thermocouple and the pilot light will go out.

What to do if the igniter of the gas column goes out

The only correct solution would be to call a licensed specialist from our service center to clean and adjust the igniter. Check the functions of the thermocouple and gas control system. Smoked gas can also extend to the main burner, which will also need the attention of the master. Usually, if the wick goes dead during operation, the adjustment of the work takes place by completecleaning gas column.

Ceased to ignite gas column  and the family was left without hot water? Do not worry, though the geyser is a complex device, but as a technical product is subject to repair.

In this article, we will consider malfunctions, we will help you diagnose the problem yourself and repair the broken node, but if the repair on your own does not give a positive result, our masters are at your service.

Remember!   Repair gas equipment without experience and knowledge and disable the automatic control system for carbon monoxide gas is dangerous to life and property.

In order to save money, self-repair will result in aggravation of breakdowns and higher prices for master services, but if you are a person with a technical background and accumulated experience in a similar field, we will describe the possible reasons and you can turn on the column.

Possible causes of failure

№1. WEARING AUTOMATICS. Faulty ignition unit; faulty heat exchanger overheating sensor; microswitch defective; bad ionization sensor; thrust sensor is faulty; faulty servomotor and hydrogenerator; solenoid valve problem.

№2. OPERATIONAL. Wear of the water membrane; burner deformation; batteries are exhausted; filter element clogging; ignition blockage; Venturi blockage; scale in the heat exchanger; cracked electrical ignition coil; oxidized contact electronic control unit.

№3. ERROR OPINION. Lack of traction; low gas pressure; add cold water; scale in the heat exchanger; reverse thrust; soot on the heat exchanger; wear water fittings; water gland wear.

Problems with contacts and automation

№1. GAS LOCK SENSORS.   The electric circuit of the water heater is consistent. If the sensor for monitoring security or monitoring the water temperature is faulty, then the electrical circuit is in a broken condition. The ignition group starting control unit will not receive battery power and gas ignition will be impossible. When opening the water, the gas column will not light up, and the owner will not receive hot water.

A faulty sensor is detected by a tester (multimeter in ohmmeter mode). You should measure the resistance in the circuit of the device by ringing for a possible break of the contact. If the readings correspond to 0 Ohm, then for the column this means the absence of thrust to remove the combustion products, therefore, when turned on, the gas will not light up. In this case, it will not be possible to make a replacement by yourself, since the part is selected according to the degree of heating of 60-120 C. An error will lead to incorrect operation of the device and the gas will go out during heating.

№2. PROBLEMS WITH REZGIG.   Flowing gas water heaters are equipped with automatic ignition. It is powered by built-in batteries. Often, you may have noticed that when you open the water tap, the spark clicks, but the geyser does not light up. Listen, if the frequency of cod has decreased by half, and the sound from the spark is hard to hear - try to buy and install new batteries. If after replacing the power supply the problem persists and the gas column does not ignite, there is a malfunction with the gas supply solenoid valve for the main and pilot burner.

Owners of speakers with manual ignition should monitor the purity of the igniter. If the gas in the pilot light does not ignite when the piezoelectric button is pressed, a spark is generated, then the problem is in the blockage of the nozzle. In this case, remove the gas column body and clean the ignition device. The parts are rinsed with running water, wiped with a cloth until they are completely dry and set in place. If after cleaning the gas in the igniter does not ignite, but ignites from a match, we change the ceramic spark ignition plug (white pin).

№3. PROBLEMS WITH ELECTRONICS.   For convenience and people with disabilities, modern gas water heaters are completely autonomous. Equipped with an electronic unit, a hydrogenerator, a modulation burner - the introduction controls the degree of heating, produces a spark to start, monitor the safety. If one of the components fails, the geyser will turn off. A common failure is the loss of contact between the unit and the microswitch, for which reason ignition is not possible.

It is impossible to repair gas heater automation on your own. The automatic unit is filled with epoxy resin (non-separable) and changes new. The lack of a circuit connecting connectors and experience in the repair of electrical circuits will not give a positive result, and disabling the carbon monoxide sensor will lead to poisoning of the owner. In this case, it is better to use the services of professional craftsmen.

Lack of annual maintenance

№4. CLUTTER CAP.   For ignition of the main burner, the igniter is built into the design of the gas column. Small dust particles are sucked into the device along with the air. They settle on the inside of the tube and narrow the gas passage. The combustion decreases, as a result, the flame goes out after the button is released and the column stops igniting. In this case, the tube is blown out with air and the ignition electrode is cleaned with emery paper.

Wrong to thinkThat the reason why the gas column ceases to be ignited is the accumulation of soot on the copper radiator. Soot interferes with heat exchange between fire and coolant, reducing efficiency. But it will not be superfluous to purge.

№5. WEAR MEMBRANE.   The membrane is a consumable item and must be replaced during the maintenance period. Neglecting this service will cause normal wear and tear, a crack will appear and the column will not work. Replacing the membrane is not difficult even for an amateur.

When performing work on the replacement should pay attention to the strainer. It is installed when water enters the unit and serves to retain rust and debris. A clean filter is a pledge of proper operation of the water heater.

In conclusion, we say ...

Most breakdowns are due to lack of maintenance. Make it a rule: annually invite the master for maintenance work. This will extend the life of the column at times, and the appearance of a malfunction will be reduced by 2 times. The company "GazService" more than 10 years engaged in the maintenance of gas equipment. Here you can repair the water heater on the same day. We provide a guarantee for all works.

The geyser is a popular water-heating equipment of a flow type, which is most often used for organizing heating and hot water systems in private houses and apartments. Like any complex, modern unit, the gas column is subject to various failures, most of which are easily fixed on its own.

The failure of a gas column can be due to both external factors (for example, mechanical damage) and disruptions in the operation of individual column nodes. The most frequent problem faced by the owners of gas water heating equipment - the failure of the device to work when you turn on the water. Why doesn't the column turn on? There may be several reasons.

Thus, the gas column may not turn on when the water supply due to:

  • Low water pressure. This is the most common reason. You can check the pressure by opening any cold water tap.
  • Pipeline clogging. Low water pressure may be caused by blockages in the pipes. In order to troubleshoot, you should contact the housing office. That housing office should monitor the health of water lines.
  • Malfunctions of a water receiving unit of gas equipment. We are talking here about the mesh filter and the membrane, which are located at the inlet of the water node. The filter can be either mechanically damaged or clogged with lime deposits.

In addition, the ignition of the column may not be included due to insufficient ventilation traction. This can be caused both by clogging of the air duct and the ventilation passage. The first malfunction can be fixed by hand. To do this, dismantle and clean the chimney. The second problem can be fixed only by specialists.

What to do if the column is not included

If the column failure from work is caused by low pressure in the water supply system, then it is necessary to determine whether this phenomenon is temporary or the pressure in the pipeline decreases systematically.

If the pressure drops in the system are frequent, then you can install a pump in the apartment that increases the water pressure or replace the column with a model that is more suitable for the performance of the plumbing.

There are also models of geysers with a water pressure control lever. Such a model would be useful if the pressure in the faucet is good, but not sufficient for the normal functioning of the column. With the help of the lever it will be possible to “tune” the column to the existing pressure. Which option to choose depends on the financial capacity of the apartment owner.

The membrane is often deformed after 2-3 years of operation of the equipment. To change a part, in the event that it has mechanical damage (for example, breaks), is elongated in one direction. You can inspect the condition of the membrane by removing the cover from the water receiving unit. It is better to change the rubber membrane to silicone: the second one has a longer service life.

To understand how clogged the filter is, you need:

  1. Remove the water intake from the equipment;
  2. Disassemble the unit by unscrewing the nuts;
  3. Inspect the filter cells for contamination.

The filter can be cleaned with strong water pressure. Before carrying out any repairs, shut off the water and gas supply to the equipment.

Geyser doesn’t turn on: troubleshooting

The geyser the automatic machine is the equipment in which ignition happens automatically, at water inclusion. Such speakers are powered by built-in batteries (batteries, rechargeable batteries).

The most common cause of a column being out of service is the discharge of a nutrient.

Contrary to the statements of manufacturers, the service life of nutrients rarely reaches one year: they have to change batteries more often. You can do it easily with your own hands. In order to make sure that the batteries or the battery are low, you should check the on / off key for proper operation. When choosing batteries, it is better to use the recommendations of the manufacturer.

To replace the batteries you need:

  1. Take out a container with batteries (often located in the lower right part of the column) by moving the lower lever and prying the container with your fingers;
  2. Remove the batteries and replace them with new ones, taking into account the polarity;
  3. Insert the container into place (press in until a characteristic click is received);
  4. Return the lever to the same position.

Geyser Dion does not ignite: determine the shortcomings

The comfort and safety of all residents of the house depends on the correct operation of the gas equipment. One of the most common causes of fire situations is the absence of ignition in the column. At the same time, the equipment can be turned on, but go out after 2-3 minutes of proper operation. In this case, the problem is most often associated with the lack of sufficient traction.

In addition, the column may not be lit if:

  • Cold water pressure is higher than hot water pressure. In this case, it will be enough to adjust the pressure.
  • The ionization sensor is broken. In this case, the column will work after switching on for only a few seconds. At the same time, the spark ignition will go often enough. If the Dion column does not ignite for this reason, you will need to clean the electrode.
  • During operation, the solenoid valve or servomotor has worn out. This crash will be signaled by “popping” when the speaker is turned on. If the column does not start for this reason, then the elements will need to be replaced. The ignition fuse should be cleaned beforehand: the problem may lie in its contamination.

What to do if the gas column does not turn on when water is turned on (video)

The geyser is a popular water-heating device which, as well as any other, is subject to breakages. The reasons for the refusal to operate the gas water-heating equipment are often associated with the wear and tear of the elements of the water receiving unit of the column, the weak pressure in the water supply system, the discharge of nutrients. It is possible to eliminate most faults of this kind without the involvement of specialists. The main thing is to correctly identify the malfunction and carry out any repairs, having previously shut off the water and gas supply.

Domestic gas heaters (columns) are designed to provide consumers with hot water. By the principle of inclusion are divided into automatic and semi-automatic. In automatic columns, an electric spark generator unit is responsible for igniting gas burners; in semi-automatic columns, gas burners are lit from a gas wick, with each analysis of water.

In the article we will analyze what to do if a gas column with a semi-automatic ignition system does not light up, the principle of operation of the ignition system, the causes of a malfunctioning gas wick and methods for their elimination.

The principle of operation of semi-automatic gas column ignition system

The ignition system for semi-automatic speakers consists of:

  • gas valve with electric flame control;
  • piezoelectric element;
  • wick;
  • thermocouples;
  • sensor control overheating of the coolant and the absence of thrust in the smoke removal chamber;
  • connecting wires.

The scheme of emergency shutdown of the gas valve of semi-automatic gas water heaters (columns).

When you press the gas valve knob and turn it counterclockwise until it stops, the electric valve opens, the piezoelectric element generates a spark, as a result, the wick is ignited and the thermocouple that generates the emf is heated. After 10-30 seconds, the voltage should be 15 - 30 mV. This voltage is enough to trigger the magnet, which holds the valve stem in the open position. When the protection circuit is broken, the current disappears, the controlled valve moves to the closing position under the action of the spring. Gas stops flowing to the burners and wick.

The reasons for the lack of flame on the wick gas column

  1. Air hole in the wick is clogged. Air is supplied through this opening to ensure the combustion of natural gas at the tip of the igniter.
  2. Solenoid valve coil burned. The electric magnet holds the valve stem, after it breaks, the valve will be closed.
  3. Thermocouple failed. The thermocouple, while in a flame, produces a voltage applied to the electromagnet.
  4. Defective sensors monitor the temperature of the water and the state of the chimney (the presence of thrust). With a value of up to + 82 ° C, the sensor is in the closed position, above this temperature its bimetallic plates diverge and the circuit opens. Break the normal contact between the two plates can oxidation of the surface, mechanical or thermal damage to them.
  5. The electrical circuit of the flame control system has been broken. All elements of the flame control system are interconnected by wires. Their failure will inevitably lead to disruption of the entire system.
  6. The nozzle or gas supply tube in the wick is clogged. The inner diameter of the tube is 2.5 mm (outer 4 mm) diameter of the nozzle outlet 0.1 mm. These elements may become clogged with soot, dust, etc.
  7. Violation of the piezoelectric element, the spark of which ignites the gas.

Identifying the reason why the gas column does not ignite and the elimination of damage

To determine the cause of the absence of flame in the wick column, you must:

  • Open the instrument faceplate.
  • Check the condition of the nozzle and the air suction openings, gas supply tubes to the igniter. In the presence of soot, dirt: remove it from the wick.

The ignition system of semi-automatic gas pumps.

  • Investigate the piezoelectric element for the presence of spark generation. If not, inspect the wires, terminals for mechanical and other damage. Oxides on the contacts must be removed, damage repaired.

The location of the elements of the semi-automatic gas column are responsible for the ignition.

  • Determine the thermocouple voltage. To check the heat generator, unscrew the special plug of the electric valve. Carefully remove the special cable that comes from the thermocouple. Using a miltimeter in the DC voltage test mode, connect one probe through the Crocodile clip to the outer shell, and lean the other to the central contact. Since the height of the placement between the contacts is small, make sure that the probes do not touch each other. Lighter warm the working end of the thermocouple. If the readings of the voltmeter correspond to 15 - 30 mV, the part is in good condition, for other values ​​the generator must be replaced. If the special wire is not suitable for further use, replace the entire thermocouple.
  • Investigate the valve inductance. Insert one end of the probe into the valve connector that was released when checking the thermocouple, in the middle of the connector and the other on its body. Tester mode ohmmeter. Coil resistance should be in the range of 10 - 15 ohms. If the circuit is open or short-circuited, the ohmmeter will record 1 or 0, respectively. The coil changes modularly, along with the stem and valve.

Measurement of the resistance of the coil of the solenoid valve gas column.

  • Check the health of the monitoring sensors. At room temperature, the control contacts of the sensor are in the closed state. With a multimeter, in diode test mode, examine the two terminals of the sensor for the integrity of the circuit. The tester reading when the sensor is in good condition will be 0, in other situations when the values ​​correspond to 1 or the resistance is 1 - 600 Ohm, it should be removed, and in its place it should be installed in good condition.

Location of the water temperature sensor and gas column chimney sensor.

  • Test the condition of the wires and connections. The wires with the contacts of the sensors are connected by soldering with soft solder, with an electromagnet and a thermocouple with a special plug. Carefully inspect the wires, soldering points, plug connection. Sometimes in the places of soldering microcracks are formed, because of which the integrity of the whole chain is broken.

After each eliminated note, it is advisable to check whether the column lights up or not.

Geyser Bosch - Troubleshooting

About six months ago, I bought myself a Bosch WR 10-2p gas water heater. I installed it myself, and during the work there were no problems, it never flowed. Soot accumulated in it now, and it stopped heating the water. I decided to do the cleaning myself. Share your experience how to do it. How to remove the copper tube? To do this, just raise the bracket and the tube is removed? And I also want to remove the heat exchanger in order to completely wash it off of any contaminants. I also noticed that the flame changed its color. If earlier it was even blue, now it is blue and yellow. Why is she so dirty?

You have a bad flow of fresh air, so a lot of soot is formed. You need to blow dust off the burner and rinse the heat exchanger well. Works for about 2 hours and the WR10-2 p23 instantaneous water heater will be fine.

I have a gas water heater Bosch WR 13-2p semiautomatic. She has been working for 5 years, but now there is a problem. As soon as the cold started, strange things began to happen to her. And the water pressure is very good, the gas is also supplied with sufficient pressure. But the water enters very cold, so that in order for it to heat the water properly, it is necessary to set a higher temperature in the settings. With this mode of operation, after 5-10 minutes of heating, the unit turns off. I absolutely do not understand his device, but that's what it seems to me. I suspect that the problem is in some kind of sensor responsible for overheating. Perhaps it is very dirty, or broken, and gives a false signal to the water heater. Or maybe my chimney is dirty? How do I repair the device?

Most likely you have broken chimney draft, and therefore the Bosch column is turned off. The overheating protection is activated; the thrust sensor is responsible for it. Judging by the time after which the device turns off, then it is him. But other options are possible. For example, if your model has a battery, then it could sit down. You just need to replace it. Check the operation of the overheating sensor is simple. It is necessary to close the contacts. If the water heater continues to turn off, then this is not due to it. The contacts in the “thermocouple – sensors” circuit may have oxidized or become loose. Then it will be necessary to check all contacts. Perhaps a large accumulation of soot on thermocouple. Then you will need to clean it. Perhaps the flame does not hit the thermocouple, then it will be necessary to clean the igniter. Gas-fired instantaneous water heaters WR13-2 p23 are available with both a thermocouple and an automatic ignition, in which the electronics is powered by batteries. You have a gas boiler with a thermocouple. It is connected in series with a thermocouple, gas valve and overheating sensor (thrust sensor). If there is poor contact at any point in this circuit, the gas valve closes. Accordingly, the column goes out. In order to check whether the thrust is really good, it is necessary to close the contacts on the overheating sensor. If the device starts to work normally, it means the sensor is faulty, or the problem with the burden. If it continues to work incorrectly, then you need to look at the height of the flame, and how much it falls on
wick. Very often, the Bosch wick is tuned to minimum power, and if the thrust is strong, it deflects the flame to the side, naturally it goes out. You need to inspect the water heater to say something more specific. In any case, you will have to correct this damage, since if the draft sensor is faulty, it is forbidden to use the unit.

I decided to buy a gas heater Bosch W10 kb. I studied it from all sides. I have a chimney, this is a pipe with a diameter of 12 cm, 2 m of this pipe lies under the false ceiling, and then it also hangs down from the ceiling at 1 m. I want to leave a pipe with a diameter of 12 cm running along the ceiling, and replace the rest with a pipe with a diameter of 6 cm. As I understand it, at the junction of pipes 12 cm and 6 cm, the pressure should drop by 2 times. That is, the flow will slow down. The chimney is even wider, so there the pressure should drop even more. Is this model equipped with a powerful enough fan to avoid problems with its neighbors?

Bosch column can be easily connected by implementing air intake from the room. If you look at the instructions, it is written there in detail. Make the transition between the pipes 6 cm and 12 cm, then connect your corrugation. All connections should be well insulated, as there gas is supplied under pressure. Your chimney does not affect your neighbors. Everyone has their own access to the roof. You can also install a splitter to make air intake from the street, and the emission of combustion products is already in the chimney. Holes less than 15 cm can not be reconciled with anyone. Coaxial pipeline to bring to the street is not worth it, because you need to respect the distance to the nearest window. If you do not live on the top floor, it is unlikely you can provide it.

Can you please tell the gas column Bosch WR 13-2b (gwh 15) on electronics. I went to different shops, sales assistants are constantly confused. I am afraid that they will bring the wrong one. Tell me more, what do the dances of the names 2B and 2P mean? Is there a flow meter on one of them? If you know how much water has passed through the electronic unit, the column should automatically calculate how much gas
  need to heat water? Why then do these models work so badly? I do not understand. It should keep the temperature much better than the mechanical one.

The number 2 means the line number. The letter P means that the water heater works with a constantly burning igniter.

Gas control is carried out using a thermocouple. The letter B means that the device runs on batteries. In it, the igniter burns only when it is ignited. Gas control using ionization. The numbers after WH are the number of liters per minute, which, at a temperature of 25 degrees, when installed
  gas pressure is passed through the unit at the inlet. Any column where the mechanical drive of the gas valve from the membrane is realized, and the manual adjustment of the gas supply by the valve is installed, is considered mechanical. In the electronic model of a water block with a membrane is not structurally provided. Also, there is no manual adjustment of the gas supply using a special knob switch. It sets the necessary
  temperature, and everything else is done automatically. Also there are installed inlet and outlet temperature sensors, and a sensor for air flow and turbine speed.

How to turn on the gas column Bosch WR 10 - 2P?

It turns out that, whatever the power is set, the device is tuned to automatic combustion mode, to maintain the required temperature. This reduces gas consumption, significantly reduces emissions to the atmosphere, and increases the efficiency of the device. Such water heaters work without problems. But they usually connect to 220 volts. Since all the automation and other devices operate on the network. Mechanical models could never maintain the required temperature, since they do not have such systems for this. There was an attempt to release a valve-membrane device Bosch Junkers not only for ignition, but also for modulating the burner. But this line was not successful.

I have installed a Bosch 10 gas column. And adapted for working on liquefied gas. To do this, I installed the other nozzles, and removed the jumper j6. But the device does not start, and I do not understand why. When I turn it on, the green button lights up for a few seconds, and then the red light blinks, and the fan starts to work. No more action takes place.

Since the unit reacts to the inclusion of water turning on the fan, then first of all you need to make sure the pressure switch. This is the weakest point of all smoke exhausts. If the fan turns on when the faucet is closed, and at the same time it is blocked, you need to look at the sensors and look for a break. The pressure switch contacts may be incorrectly connected or interchanged. After you retooled the water heater, it was necessary to test its operation on a gas heater in order to make sure that the unit is in good condition and that there are no breakdowns in it. On delivery it could be damaged. And so check under the scheme. Ring the thermal sensors, check the pressure switch. If it works, go to setup mode, set the regulator to maximum. To do this, you must press and hold the torch buttons and then switch the switch that you need to hold until it starts blinking. Also check the fuses located in the control unit.

From my gas column Bosch 15 began to flow water, and it flows out of its upper part. In operation, it is already 8 years old, and before that it had never broken. Can I repair it?

Hardly. Get ready to buy a new water heater.

There was a malfunction of the gas column Bosch WR 10-2 p. 4 years she worked without any problems, but a month ago she began to leak radiator. In order to find the flow, I took it off and watched. I found top damage. Soldering there is impossible because of the edges. In order to block the leak, I filled the defeated place with sealant. At the same time I washed the radiator. The water heater began to work well. But now there is a new problem. The device has stopped burning. The pressure is good, but the water on the faucet flows cold. If you look through the viewing window, the gas burns not with blue, but with a yellow flame. Also the burning power is much less. What could break? Traction is present, I checked it with the help of a lit newspaper. Gas is supplied with good pressure, checked with a gas stove that burns without problems. The boiler connected to this gas also works.

On a gas-fired gas heater WR10-2 p23, try disassembling and flushing the heat exchanger and the burner. You also need to blow the igniter. This should be done as soon as the flame begins to change color. To solve the problem, try to unscrew the two screws on the side and in the center, but do not remove them completely. Use a flathead screwdriver to hook the torch and pull it out. Find a rubber ring there. Do not forget to grease it or soap, or a special silicone grease. Also find the wire with the solenoid valve and turn it off; without it, you will not be able to disconnect the burner from the unit. The heat exchanger will also have to be removed, as it will interfere with dismantling the burner.

I have a gas water heater Bosch WR 15. I turned off the old electric boiler and carried it away, and in its place installed a device with a generator. Now nothing works. Water is supplied with a pressure of 3 atmospheres. The gas pressure is 2000 MP, instead of the prescribed 1300. That is, everything is supplied as it should. We started it like this. For the first time ten attempts, after the hot water tap was opened, they heard clicks from the water heater, and then an EA error appeared. The manual says that there is no gas on the main burner. Tried not to run once. After that the flame appeared. The water began to heat up, but not to the desired temperature. The device shows 58 degrees, but in fact the water is much colder. And then the flame went out again. It seems to me that some valve does not work to the end. The height of the flame is not more than 4 cm. To solve the problem, I want to try to adjust the gas pressure before the burner. Is it correct?

The pressure is enough for the device to work correctly. But note that it should be measured not only when the water heater is off, but also when it is running. It should not fall below 13 millibar. If the pointer shows 58 degrees, then he could theoretically heat such a temperature.

Initial startup problems are also logical, there was air in the system and it took time for it to go out. The flame is extinguished most likely due to the activation of the protection, perhaps you have problems with the burden.

Check contacts and sensors. Also check the amount of power from the generator using a multimeter. A sticking valve usually either opens or does not open. You can try to blow the gas valve, but not more than 0.3 kg / cm. For more pressure, it is not designed. You can also check the valve with a 3 volt battery, a click sounds when it is triggered.

Faulty gas water heater Bosch WR 10-2p. Clicks are heard when starting up, and even sometimes it lights up, but only if the water supply valve is open to the maximum. The water is warm but not sufficient. It used to be much hotter. After the device starts up, the water supply pressure can already be reduced, and everything will work. If the unit does not want to work at all, I blow cold air on it, and the problem is solved. But you need to clearly find the point at which to blow. It is located next to the green indicator. During this procedure, the indicator flashes, and after a while the device starts to work. Gas is supplied at normal pressure. What could be?

Try using the right control knob to reduce the flow. To do this, turn it in the direction of increasing the temperature to an average value. If you blow air on a valve or a pilot light, then you just need to clean the unit from dust. A spark should always appear.

Launched into operation gas column Bosch WR 13-2. I adjusted the pressure, it is as it should be. But I am confused by the fact that if the tap is not fully open, at least in half, the unit “puffs”, but does not light up. In the passport I found the minimum water pressure. Is the minimum duct not standardized?

In the passport of the instantaneous water heater WR13-2 p23, both the rated power and the rated flow at a water temperature of 25 ° C are indicated. If the water does not heat to the point you want, then the valve does not open fully. The reasons for this may be many. Need to understand. For example, the rod of the water block does not move in full amplitude, and, accordingly, does not fully open the gas shut-off valve. Even a minimal membrane breakthrough is enough to cause this problem. Also could clog the internal valve. If to deal with the gas block, then perhaps insufficient voltage supplied from the control unit to the valve. It may not be enough to open the valve to the end. Also the membrane could tear or stretch. Could stick stock. The control unit supplies voltage, gas from the front cavity is fed to the pilot burner. The control unit receives a signal that has appeared in the flame. After that, it energizes the lower valve, which cuts off the gas supply to the front cavity. By pressing the gas in the back cavity, the membrane moves forward, and the gas supply valve opens already on the main burner. The gas comes out of the front cavity and the igniter switches off. The flame control electrode continues to fix it, as the main burner burns. Using the gas adjustment knob, you can set the spring stiffness, which counteracts the diaphragm displacement. Correspondingly, adjust the gas cock supplying gas to the main burner.

If the gas column one day did not want to burn, then you should not immediately rush to the store for a new one. The problem is resolved with his own hands. We will look at the main reasons why the gas column does not light up, and also learn how to fix problems without the help of craftsmen.

Simple checks

If the devices "Vector", "Bosch", "Orion", "Dion", "Selena" and columns of other brands are not lit, then it is worth first of all to check whether the valves that supply gas and water are open. They affect the work.

Traction in the chimney

This is one of the reasons why the gas column does not light up. If the main burner of the device ceases to ignite, then it is recommended to check the chimney, it may be clogged. A large accumulation of soot inside the chimney, various debris, leaves from the street - all this can clog the chimney so that carbon monoxide mixed with air will return back to the column. This will cause attenuation. Kindle it will not work.

Also clogged or clogged chimney can lead to the ingress of carbon monoxide into the room of an apartment or house, which can lead to serious poisoning.

In modern columns "Bosch", "Beretta", "Ariston" and other manufacturers have special sensors that are constantly in the process of the column control the level of traction in the chimney. If suddenly there is no thrust, then the supply of fuel (in this case, gas) will be automatically stopped. That is why the gas column does not light up, "Bosch" for example.

You can independently check whether there is a thrust. To do this, bring a burning match to the hole in the body of the column. If the match flame is deflected, then the chimney is working properly. If the flame does not move, the ventilation system is clogged. It is better to turn off the column and not to operate it until the chimney is cleaned.

Weak pressure in the plumbing system

If the column does not work, then you should check the pressure in the water mains. Modern devices, especially the Neva, are very sensitive to the force of water pressure and the pressure drop in the water mains. If the pressure level is insufficient, then this is the answer to the question why the Neva gas water heater and its similar equipment are not lit. The membrane of the column with a weak head does not affect the valve in any way - there is no flow to the delivery system. The column clicks the piezoelectric element, but the full ignition of the gas does not occur.

You need to open the water tap and make sure that the pressure is really weak. In this case, you will have to resolve the issue with the company responsible for the water supply. Low pressure is more common in the summer, when many people use water at the same time.

If the pressure is large, sufficient force, then you need to check the strainer at the inlet of the water node. The item is removed, check under running water. If the plaque cannot be washed off, the filter is soaked in citric acid solution.

You can apply another way. Turn off the flow of gas and water, unscrew the pipes at the inlet, remove the column housing from the wall and set upside down. Then the usual cleaning syringe is poured into the system of the cleaning agent and left for several hours.

Low gas pressure

This is another answer to the question of why the geyser does not light up. If the gas is not supplied in sufficient quantity for normal operation, the column will not work. To check the pressure, turn on the gas stove. If the fuel pressure is too low, you should immediately contact the experts. Perhaps there was a leak somewhere in the highway.

The wick does not ignite

If the column is lit, but very bad, then there may be several reasons. Consider each of them:

  • If the piezoelectric element does not work, then in the models “Astra” and Zerten there may be problems with the igniter. The wick should always burn, and it works when you open the valve or when you press the corresponding button. If the element is not working, the wick is off, then the column jets could be clogged. To do this, disassemble the device, remove the metal protection or the casing and the nozzle. Better to do it with fine wire. Usually after cleaning the jet the column works normally. This is one of the reasons why the Astra gas column and other similar devices do not light up.
  • Another case is the automatics column, which are lit for a long time. Automatic speaker ignition system powered by batteries. When the tap is opened, the device triggers and a powerful spark is formed that ignites the burner of the column. If there is no spark, then it is worth trying to replace the batteries, and better install the batteries.
  • A hydrodynamic generator may also fail. The generator rotates when water passes through it. The unit during rotation produces a current, from which a spark is then formed. If this is the reason why the gas column does not ignite, then repair is better to be entrusted to professionals.

System blockages

How to perform a strainer cleaning was written above. The heat exchanger system should also be cleaned - during operation, scale builds up on it. For this, the heat exchanger is removed and placed in water with citric acid. Capacity with a solution to warm up on the stove. Inside the heat exchanger is also worth rinsing with this solution.

In gas junk devices and other similar units, burners are often clogged. A large accumulation of soot and soot leads to the fact that the column will not ignite. In the process of cleaning the heat exchanger is to clean and burner. A solution of citric acid is washed out the external part of the device. The inner part of the burner is better to clean on the street.

Membrane and gas block

This is not a popular reason why the gas column "Oasis" does not light up. If there is deformation on the membrane, signs of wear, the burner will not ignite. The point here is in the principle of the action of the membrane. When water enters the system, pressure is applied to the membrane. It affects the gas valve - it must open and supply gas to the burner of the column.

If there are malfunctions of the membrane, then experts recommend replacing it with a silicone one. It is believed that they are more durable.

The column is lit and goes out

Many geyser owners would like to know why the geyser ignites and goes out.

The reasons for such unsatisfactory work may be in weak pitch. At the same time, the emergency system stops fuel supply and the column goes out. If the traction is in order, then the alarm relay is too sensitive. You can temporarily solve the problem with an intense air flow - all windows open for this. But the detail needs to be changed.

Other malfunctions of geysers

The work of modern speakers is controlled by electronics. The devices are literally crammed with a mass of sensors and electronic modules. Even a minor failure of one of the sensors can lead to unsatisfactory operation of the unit. Independently solve the problem will not work - you need special equipment.

Most of the owners of gas columns with too hot tap water regulate the temperature by adding cold water to the mixer. In this case, the speakers can go out. Unit manufacturers do not recommend using the column in this mode. It is better to set a lower heating temperature on the column.

Also, the speakers can work poorly with an incorrectly configured pilot light. That is why the gas column does not immediately light up. It is very important that the gas pressure in the pipeline is fully consistent with the type and design of the pilot. There is a comb on the edge of the burner, and the electrode must be installed so that the spark hits the comb directly. If the gas pressure is insufficient, the fuel goes down. The electrode should be mounted approximately to the center of the burner. Then the ignition system will work more stably.

Typical malfunctions of individual speakers:


When it is known why the gas column ignites poorly, you can make a few simple recommendations. So, you need to correctly insert the temperature regime. An optional water softener filter should be purchased. Elements of the column should be periodically cleaned from soot.

Conclusion

Thus, we found out why the geyser does not light up. As you can see, there may be several reasons for this. But in most cases it is possible to cope with the problem of an extinct gas column in the house independently, without the help of specialists.
