The water heater doesn t catch fire, but there is a sound of ignition

Water heaters have a very important application in our lives, it makes our lives more convenient, but when the water heater has some failures, it will give us a headache, let's see the solution when the water heater does not catch fire but there is a sound.

Solenoid valve failure.

Phenomenon: If only the ignition sound is heard during ignition, and there is no magnetic suction sound of the solenoid valve "clicking", it may be that the solenoid valve is damaged or aging. If the solenoid valve is aging, it can be sucked at the beginning of the ignition, and the fire will be ignited, but then the ignition will be extinguished again.

It may also be that the gas pressure is too high or too low, and the output pressure of the cylinder pressure reducing valve will be too high or too low for the water heater that uses cylinder gas, resulting in the water heater not being able to ignite.

It is also possible that the solenoid valve is dirty. If the solenoid valve cannot be overgased, the gas will not come out, so that it will not ignite. Before confirming the failure of the solenoid valve, it is necessary to confirm whether the ignition control circuit is normal, and if there is a fault, the solenoid valve cannot be controlled.

Solution: Check the elimination method one by one to determine the specific cause. If the solenoid valve is aged, replace the solenoid valve. If there is a problem with the gas pressure, replace the gas cylinder with a new one. If there is any swag on the gas valve, clean it up. If the ignition control circuit, the circuit problem is repaired.

1. Cause analysis:

Many of the reasons why you can't ignite are caused by improper operation, such as running out of oil, running out of electricity, and having the wrong gear, and these situations are quite common.

1.Out of gas. I went out to rescue a car before, but the fuel gauge showed that it was below the red line, so naturally it could not catch fire.

2.The battery is dead. It may be due to the loss of power caused by the headlights not turned off for a long time or the battery life expires, and it is generally recommended to replace the battery in time after three years.

In addition, the installation of xenon headlights, high-power audio, etc. are also the causes of vehicle circuit failures. The situation of the vehicle without power is easy to check, just press the horn to know.

3.The gear is wrong. When the automatic transmission car starts, the gear must be placed on the P or N gear, if it is placed on the R or D gear, it will not ignite. There are also some manual transmission cars that will not catch fire if you don't step on the clutch.

Second, what to do and how to solve the reason why the car cannot catch fire.

Reasons for vehicle use: improper oil, no antifreeze, excessive carbon deposit.

In addition to the reasons for improper human operation, there may also be motor failure, or oil pump oil supply, fuel injector problems, sensor failure, etc., encountering these more complex situations, need to be dealt with by professionals. However, pay more attention to the following items when using a car to avoid these complex situations.

1. Oil problem. When I was repairing a car, I found that there was water and mud in the fuel tank after dismantling it, and it was impossible to use such oil to keep the car from breaking. Therefore, it is reminded that you must go to a regular gas station to refuel, and you can bring a gauze wrapped in the muzzle of the gas gun to filter impurities.

2. No antifreeze added. Some car owners add water or inferior antifreeze to the car, resulting in a particularly cold winter, causing the entire waterway to be frozen, the engine to be frozen and cracked, resulting in the car water pump can not operate, can not catch fire, and injure other parts of the engine.

3. Too much carbon accumulation in the vehicle will also cause the vehicle to not catch fire, and the solution is to reduce the carbon deposit by running at high speed frequently. In addition, there is a small trick for not ignition, before starting the ignition, first screw the key to the ON switch, and then turn it back, and then turn on the strat switch to ignition, let the computer run to calculate the water temperature and the appropriate air intake, and the ignition will be smoother.

What is the reason why a gas water heater does not catch fire?

The water heater does not ignite and can be divided into no ignition sound and no ignition sound and no ignition

1. Battery problem: If you use a battery, you should first see if the battery is too old, and the water heater will not catch fire if the voltage is not enough.

2. Solenoid valve failure: If only the ignition sound is heard during ignition, and there is no solenoid valve "click" magnetic suction sound, it may be:

a.The solenoid valve is damaged or aged, the solenoid valve is aging, it will be uncontrolled, and it can be sucked at the beginning of the ignition, and it can catch fire, but then it closes and turns off;

b.If the gas pressure is too high or too low, the output pressure of the cylinder pressure reducing valve will be too high or too low in the water heater using cylinder gas, and the water heater cannot be ignited;

c.The solenoid valve has dirt. The solenoid valve cannot be overgased, and the gas (natural gas, liquefied petroleum gas, artificial gas) cannot come out, so that the ignition cannot be ignited.

Before confirming the quality of the solenoid valve, it is necessary to confirm whether the ignition control circuit is normal, if there is a fault, the solenoid valve cannot be controlled.

3. Ignition failure: One of the pulse igniters and controllers is faulty, and the water heater cannot be ignited normally.

4. Ignition needle or induction needle problem:

a.It is very difficult to ignite when the ignition needle is offset or aging, and the ignition needle can be replaced or placed correctly;

b.Induction aging, you can polish the induction and place it well (so that the flame can fully burn the induction needle regardless of large fire or small fire).

5. Water pressure problem: aWhen the water pressure is low, the water heater cannot start normally; b.The filter screen at the water inlet is blocked and the water cannot flow normally, so you can clean it up.

6. Failure of water-gas linkage device

a.The eardrum in the water-air linkage valve is aging or damaged, and the micro switch cannot be pushed;

b.The micro switch is broken.

7. If the air source switch is not turned on or the air inlet filter is blocked, open the air source correctly and clean the air intake filter.

8. The gas type does not match; For example, the liquefied gas water heater is connected to natural gas, so it must be clear when purchasing that it is the gas source.

9. The valve seal is corroded by gas and then swells. Replacement parts.

10. The smoke pipe cannot be exhausted normally.

a.If the smoke pipe is blocked, clean up the smoke pipe blockage; b.The smoke pipe is too long and not installed properly. Please refer to the instructions for the installation of double-layer smoke pipes for balanced water heaters.

The above 10 situations can cause the gas water heater to not start, the water heater can not catch fire, the water heater does not ignite, professionals please refer to the above methods to troubleshoot, ordinary users can also understand, non-professionals do not carry out water heater maintenance operations.

The reasons are as follows: 1. Battery problems. If you use a battery, you should first see if the battery is too old, and the water heater will not catch fire if the voltage is not enough.

2. Ignition failure. One of the pulse igniters and the controller is faulty, and neither of the water heaters can ignite properly. 3. Problems with ignition needles or induction needles.

Ignition is difficult when the ignition needle is offset or aged. 4. Water pressure problem. When the water pressure is low, the water heater cannot start normally;

5. Air pressure problem. You can only contact the gas company to resolve the issue. Suggested Treatment:

1. The ignition needle can be replaced or placed correctly, and the induction can be polished and placed well (so that the flame can fully burn the induction needle regardless of large fire or small fire). 2. Pressurization devices can be installed at home; The filter screen at the water inlet is blocked and the water cannot flow normally, so you can clean it up. 3. The water heater is ringing, but it can't catch fire, the main reason can be judged whether the battery is running normally.

4. The second is whether the circuit is stable, often when the family uses large-scale voltage and current products, it must be equipped with an electric regulator to avoid the impact of short-term current fluctuations on the machine, in addition to the problem of the battery that needs to be judged is relatively simple, you can replace the battery in a water heater by yourself, this operation is relatively simple.

It could be a problem such as a dead battery or too old. It may be caused by a faulty igniter. It could be an ignition needle or sensor needle issue.

It could be a water pressure issue. It could be a barometric pressure issue. It may be caused by the smoke pipe not venting properly.

Suggested solutions: 1. If you use a battery, you should first see if the battery is too old, and the water heater will not catch fire if the voltage is not enough, and it will also produce a "zizi" sound, so it is recommended to replace the battery with a new one. 2. If one of the pulse igniters and controllers is faulty, and the water heater cannot be ignited normally, and there is noise, it is recommended to replace the new equipment directly.

3. If it is very difficult to ignite when the ignition needle is offset or aging, it can be replaced or placed correctly in the ignition needle, and the induction can be polished and placed for normal use. 4. When the water pressure is low, the water heater cannot be started normally, you can install a booster at home, or the filter screen at the water inlet is blocked and the water cannot flow normally, so you can clean it up. 5. You can only contact the gas company to solve the problem.

6. It may be that the smoke pipe is blocked, clean up the smoke pipe blockage, or the smoke pipe is too long and not installed correctly. This requires a professional maintenance master to come to the door for maintenance processing, and do not operate it at home.

Summary. It may be a water pressure problem.

When the water pressure is low, the water heater cannot start normally; The filter at the inlet is blocked and the water cannot flow normally, so you can clean it up.

The water heater ignition has no sound.

Do you have any other questions? The order will automatically close after 24 hours, if I am helpful to you, I look forward to your like, thank you

1. Battery problems. See if the battery is too old, and the voltage is not enough to make the water heater not catch fire.

2. Solenoid valve problem. If there is no magnetic sound of the solenoid valve during ignition, it may be because the solenoid valve is damaged or aging. The solenoid valve is aging and will be uncontrolled, and it can be engaged at the beginning of the ignition, but then it closes and turns off.

Water heater maintenance tips:

1. When the water heater is not in use for a long time, turn off the power supply and drain the water storage of the inner tank; If the water output of the shower is reduced, it is necessary to clean up the blocked debris in time to ensure that the outlet is unobstructed, which is helpful to prolong the service life of the water heater.

2. If the water heater is not used for a long time, the power plug should be unplugged first, so that the water heater is in a power-off state, which is mainly for safety, and the water heater is in working condition if it is not used for a long time, which will lead to accelerated aging of the components in the water heater and shorten the service life of the water heater.

1. It may be that the solenoid valve is damaged or aging, resulting in the water heater not catching fire and making a sound.

2. It is also possible that the gas pressure is too high or too low, and the cylinder pressure reducing valve will appear in the water heater using cylinder gas, and the output pressure will be too high or too low, resulting in the water heater not being able to ignite.

3. In addition, if there is dirt in the solenoid valve, the solenoid valve cannot be overgasped, and the water heater will also have the problem of not igniting and making a sound.

The solution that the water heater does not catch fire but has a sound.

1. First of all, check whether the solenoid valve is aging or damaged, if you can only hear the ignition sound when ignition, and there is no magnetic sound of the solenoid valve, this situation is that the solenoid valve is damaged, then you need to find a professional maintenance personnel to replace the new solenoid valve, and after the replacement, you can solve the problem that the water heater does not catch fire and has a sound.

2. If the gas pressure is too high or too low, then you need to replace the new gas cylinder, and the water heater can be ignited normally after replacement.

3. In addition, it is necessary to check whether there is any dirt in the solenoid valve, if there is dirt, then it is necessary to clean up the dirty things, and this problem can be solved after cleaning up.

4. If these problems are ruled out, and the lead is still not on fire, then it is recommended to contact professional after-sales maintenance personnel to come to the door for maintenance.

What to pay attention to when using an electric water heater.

1. When using the electric water heater, be sure to connect the water source, wait for the water outlet pipe to have a water flow before turning on the power supply for heating, and never turn on the power supply immediately before it is filled with cold water.

2. The faucet of the electric water heater is often equipped with a reflux device, and it will also be divided into blue and red marks to indicate cold and hot faucets. When in use, rotate the red faucet and the hot water will come out immediately, if the hot water temperature is too high, and at the same time unscrew the blue faucet, you can adjust the amount of water and the water temperature.

3. When using the electric water heater, you must not frequently switch on and off the water source, this will make the insufficient water storage in the water tank will burn out the electric heating accessories, you must pay attention to the water storage or water flow when adjusting to the temperature, if the water storage is insufficient or the water flow is very small, the time is too long, it is very easy to let the accessories overheat and cause burning. New electric water heaters are generally equipped with automatic power cut-off equipment, when the water is cut off or the water source is turned off, the water heater will automatically shut down, so that the water heater will be safer.

4. After using the storage electric water heater for a period of time, the water tank should be cleaned, and the cleaned sewage will be discharged from the discharge valve at the bottom of the water tank, so that we can use clean water.
