The German Italian gas water heater caught fire and then went out

I have encountered this kind of problem, that is, there is a sensor needle wet, rusty, carefully disassembled, sanded with sandpaper, dried with a hair dryer, and the thread of the sensor needle to be bandaged, do not omit, and I looked for it on the Internet, the information is as follows: if it is the second case, only find a special water heater maintenance master, if you have strong hands-on ability, you can also do it yourself!

There are two possibilities for this:

First, there is a problem with the feedback loop. The gas water heater has a relatively long needle, which is mounted horizontally above the fire row, and its function is to detect whether the flame is normal, and feed back this information to the pulser to determine whether the gas solenoid valve (automatic control element, when the gas cannot pass through and the water heater is extinguished when it is in the "release" position), the action or not. If the feedback pin is excessively aged, or the feedback cable is loose or lapped, it may cause the flame to stall.

In the second case, the diaphragm plate is broken. The diaphragm plate (also known as the membrane) is the cutting-edge mechanism of water pressure control, and due to the long-term compression of tap water pressure, it will crack or harden with the extension of service life. When rupturing, the impact water pressure can drive the micro switch to close and close to form a loop, and the water heater ignites and enters the working state.

However, when the water heater enters the normal working state, the ruptured membrane causes the diversion of water pressure due to the shunt, which cannot continue the maintenance of the micro switch, the current loop is interrupted, the solenoid valve is actively closed, and the flame is naturally extinguished.

Check the water pressure, check the battery. Make sure there are no problems and then suspect problems with the igniter and induction needle.

1. The battery of the gas water heater is broken and not energized, resulting in no ignition, or extinguishing after ignition; 2. The solenoid valve of the water heater is broken, causing it to go out after ignition; 3. It may be that the water diaphragm of the water-gas linkage valve is aging, so it cannot be ignited; 4. The control element of the igniter is partially broken and cannot work normally; 5. The water pressure of the water heater. Solution: 1. First check whether the ignition indicator is on, which means that the ignition is normal, and if it is not lit, you need to check that the battery is good, and the battery needs to be replaced with a new one.

2. If the solenoid valve of the gas water heater is broken and cannot be ignited, it is necessary to ask professional maintenance personnel to check the solenoid valve, and it should be replaced in time if it is seriously damaged and endangers safety. 3. The water diaphragm of the water-gas linkage valve of the water heater can not be ignited when it is aged, the water diaphragm is an important component of the work, and the water heater is used for a long time, and it will be aged if you do not pay attention to timely inspection and maintenance, so it is necessary to replace the water diaphragm in time. 4. If the control element of the ignition is partially broken, replace the new element in time.

5. If there is a little fire and sparks, and it will be extinguished quickly when it ignites, it is a problem of water pressure. You need to open the faucet to check whether the water pressure is too low, if so, there is only the peak period of staggered water use, or the inlet filter of the gas water heater is blocked, so that the water cannot flow normally, then the water heater will not ignite, and the filter needs to be cleaned. 6. After use, check whether the burner flame is extinguished and remember to close the gas valve.

The reasons why a gas water heater catches fire and goes out are as follows:

1. First of all, look at the water pressure, the water pressure is too small, the water heater will not work, as long as you open the faucet to see if the water is smooth, it means that the water pressure is not smooth.

2. Look at the air pressure, the air pressure is not normal and can not be heated, if it is a cylinder, but also to see if it is a problem with the pressure reducing valve, if you use a rubber tube to see if it is folded and deflated, resulting in a gas path.

3. Consider whether there is a problem with the pulse igniter, its high-voltage circuit cannot work normally, and can only form a high voltage for a short time, so it will also ignite for a short time.

4. If it is battery-powered to ignite, consider whether the battery is out of power, and if there is a problem with the two, only replace it.

5. Whether the wind pressure switch is faulty can be corrected by adjusting the "+" screw on its back.

6. Consider the feedback pin and its connecting cable, which can be eliminated by replacing the feedback pin and reconnecting the feedback cable.

7. Finally, there is a problem with the CPU processing unit, which can only change the circuit board.

There can be several reasons why a water heater turns off after it turns on fire, and here are some of the common possible causes:

Gas Problems: A common cause of a water heater flameout is a gas issue. It may be that the gas pipeline is blocked, the gas valve is closed or malfunctioning, or the gas pressure is unstable, which causes the gas ** to be interrupted, which causes the water heater to go out.

Ignition failure: A faulty igniter of a water heater may cause the ignition to go out immediately after ignition. The igniter may be damaged, dirty, or unable to produce enough sparks to sustain the burn.

Combustion Chamber Problems: Problems with the combustion chamber of a water heater, such as blockages or abnormal airflow, can lead to unstable combustion and eventually lead to flameout.

Thermostat failure: The thermostat is a critical component in controlling the temperature of the water heater. If the thermostat fails, it may cause the hot water hand to fail to maintain a constant temperature, which may cause the flame to stall.

Exhaust problems: Problems with the exhaust system of the hot water field, such as blockage or poor installation, may cause the exhaust gas generated by combustion to be unable to be discharged smoothly, causing the water heater to stall.

Summary. 1. It is possible that the air inlet channel of the water heater is blocked by foreign objects, resulting in insufficient oxygen, so there will be ignition and then extinguishment.

The gas water heater goes out as soon as it ignites.

Mistake. It should be unplugged immediately.

The water heater will be extinguished after 3 seconds of ignition.

1. It is possible that the air inlet channel of the water heater is blocked by foreign objects, resulting in insufficient oxygen, so there will be ignition and then extinguishment.

2. It is also possible that the gas pressure of the gas water heater is insufficient, so the gas ** is insufficient.

3. It is also possible that the induction needle of the gas water heater is aging, and the most obvious manifestation is that the surface is rusty.

Suggested solution: 1. When the user finds that the gas water heater is on fire and then extinguished after a while, it is recommended to check whether there are foreign objects in the channel of the air inlet. In particular, when this passage is installed outdoors, it is most likely to be blocked by foreign objects.

At this time, it is necessary to use tools to clean out the foreign body, clean it up, and you can ventilate normally.

2. If the gas pressure is insufficient, the user can choose to turn the gas switch slightly larger to release more gas. If it still doesn't work, then you need to ask a special home appliance maintenance personnel to deal with it, and some parts may need to be readjusted.

3. The user can first observe the surface of the lighter, if there is obvious rust, then it means that the lighter is aging, and then it needs to be replaced with a new lighter. It is recommended to consult a dedicated home appliance staff when purchasing and selecting to avoid mismatched parts.

Hello, dear and happy, I am honored to answer for you. The gas water heater will be extinguished immediately when it is on fireAnswer: The reason for the automatic flameout:

1. The water heater has been used for a long time, and the internal joints are loose, so you can tighten it or replace it with a new one. 2. If it has been used for more than two years, it may also be that there is a problem with the induction needle of the water heater and the conductive function is not good, so it must be replaced. 3. The igniter is broken, and the water heater will react naturally after ignition, but it will go out again in a few seconds or so because of insufficient heat induction, which must replace the igniter.

4. The solenoid valve is broken. 5. The battery is out of power, and the battery must be replaced. 6. The source water pressure is low, you can try to turn on the water heater at different times.

7. Sometimes this phenomenon will occur because of the backfilling of the smoke exhaust pipe, as long as the hood is installed in the smoke exhaust outlet, the problem can be solved. Gas water heater refers to a gas appliance that uses gas as fuel to transfer heat to the cold water flowing through the heat exchanger through combustion heating to achieve the purpose of preparing hot water. It is mainly composed of valve body assembly, main burner, small fire burner, heat exchanger, safety device, etc.

It also includes the flue of flue water heater and the strong exhaust device of strong exhaust water heater. The basic working principle of the gas water heater is that the cold water enters the water heater, flows through the water-gas linkage valve body, and under the action of a certain pressure difference of the flowing water, the water-gas linkage valve is pushed, and at the same time, the DC power supply micro switch is pushed to turn on the power supply and start the pulse igniter. Gas water heaters are highly regarded by users because of their characteristics of instant on-the-flying, no need to wait, and small footprint.

Dear Hello Deyi gas stove sliding fire extinguishing from Hunger Mountain may be caused by the following reasons:1Low battery or poor battery contact:

The ignition system of the German-Italian gas stove is usually battery-powered, and if the battery is low or the battery is not in good contact, the ignition signal will be unstable, which will cause the stove to extinguish the fire automatically. The workaround is to replace the battery or adjust the contact of the battery. 2.

Problems with gas pipelines or valves: Problems with gas pipelines or valves, such as clogged gas pipelines, damaged valves, etc., will lead to instability of gas**, which will lead to automatic fire extinguishing of the stove. The solution is to inspect and repair gas lines and valves.

3.Faulty or foul flame sensors: German-Italian gas stoves are usually equipped with flame-only sensors to detect whether the flame is burning properly.

If the flame sensor is faulty or contaminated, it can cause the cooktop to extinguish itself. The solution is to clean or replace the flame sensor. 4.

Incorrect installation of the flame sensor: Incorrect installation of the flame sensor can also cause the cooktop to automatically extinguish the fire. The solution is to adjust the installation position of the flame sensor.

5.Unstable gas pressure: Unstable gas pressure can also cause the cooktop to automatically extinguish the fire.

The solution is to adjust the gas pressure. If you encounter the problem of automatic fire extinguishing of the German and Italian gas stove, it is recommended to contact a professional maintenance personnel for inspection and repair to ensure the safety of use.

The main reasons for this problem and its maintenance methods: 1. After the gas stove is turned on, the flame must be burned to the thermocouple. If the fire hole is blocked, it is difficult to meet this condition, so automatic flameout of the gas furnace may occur.

Just remove the blockage from the fire. 2. When in use, because the thermocouple has been used for a long time and the signal provided to the pulse generator is not strong, the pulse generator will mistakenly think that there is no flame and automatically close the solenoid valve. At this point, the thermocouple sensor can be replaced with a new one and it can be restored to normal.

3. Abnormal feedback circuit, such as misconnection, grounding, aging, etc., will weaken the signal, affect the pulse generator, and cause the gas furnace to go out. For users who are not familiar with the stove circuit, it is recommended to ask professional maintenance personnel to carry out relevant repairs. 4. If the battery is not regularly replaced, the battery is insufficient, and the gas stove will be automatically turned off.

You can buy the corresponding model of battery in the store.

The reasons why the German-Italian gas stove is always extinguished automatically after ignition are: insufficient natural gas, failure of the flame-out protection induction needle, too large or too small damper, failure to place the fire cover in the correct position, and the unsuitable distance between the metal rod at the top of the lighter column and the stove.

1. There is not enough natural gas

We need to check whether the natural gas is sufficient, if the natural gas is in arrears or runs out, resulting in a small amount of natural gas left in the pipeline, it will be extinguished. You will need to pay a gas bill, or make up the gas for you.

2. Flame-out protection induction needle failure

This situation needs to be repaired, please call the local service **.

3. The damper is too large or too small

If the damper is small, it is a yellow fire or a red fire, wasting gas, and if the damper is large (especially the small fire in the inner circle), it will not be easy to ignite the fire. The damper needs to be adjusted. Adjust the small damper first to make the gas concentration high, and adjust the damper to the blue flame after the ignition of the fire, but the bottom of the flame does not leave the pores.

4. The fire cover is not placed in the correct position

It may be that after cleaning the fire cover on the stove head, the fire cover is not placed in place, except for the same hole of the same size for a week, there are two small holes next to each other below, which should be facing the ignition needle), causing slow gas conduction and slow ignition. The fire cover needs to be reinstalled.

5. The distance between the metal rod at the top of the lighter column and the stove is not suitable

The distance between the metal rod at the top of the porcelain and the stove should be just right, if the distance is large, there will be no spark, if the distance is close, it will be easy to spark, but the arc is too short, and it will not ignite. It is better to have a pure track distance of about 1cm.

Hello dear! After the gas water heater is ignited, it is still ignited after a few seconds and then turned off, which is a long ignition failure, usually because the ignition feedback needle or controller is faulty. As soon as the control device receives the signal, it confirms that the ignition of the machine is successful, and the ignition system is turned off and enters the normal working state.

Once the flame leaves the feedback signal of the feedback needle, the machine will automatically shut down, which is the unexpected flameout protection function of the water heater. Check whether the contact between the feedback needle and the flame and the link between the controller is good. Check the rock digging to see if the battery is dead, or maybe the pipe is blocked.

Hope it helps.
