What is the reason why the water heater won t catch fire? Is there any workaround?

One of the reasons why the water heater won't catch fire: power supply problems.

The solution to the water heater not catching fire: check whether the AC power plug indicator is on, and remove the power supply first.

points the problem. The second reason why the water heater cannot catch fire: the solenoid valve is faulty.

The solution to the water heater not catching fire: if only the ignition sound is heard when the water heater is ignited, there is no solenoid valve "clicking" magnetic.

Sound absorption, may be due to the solenoid valve damage or aging, solenoid valve aging, will be uncontrolled, can be sucked at the beginning of the ignition.

When it closes, it catches fire, but then it closes and goes out; It is also possible that the gas pressure is too high or too low, and steel is used.

The output pressure of the cylinder pressure reducing valve will be too high or too low in the bottle water heater, and the water heater cannot be ignited; More.

It may be that the solenoid valve is dirty. The solenoid valve can not be overgas, gas (natural gas, liquefied petroleum gas,

Artificial gas. They will not be able to come out, they will not be able to come out, so that they will not be on fire. Confirm the igniter before confirming the quality of the solenoid valve.

Whether the control circuit is normal, if there is a fault, it cannot control the solenoid valve sucking.

The water heater is not ignited, you can first check whether the water, electricity and gas at home are normal, there are many reasons for not ignition, the water pressure is too low may also cause the water heater to not ignite, pulse igniter failure or poor internal wiring contact may occur without ignition, it is recommended to find the manufacturer after-sales door-to-door inspection.

There are a variety of reasons why an electric water heater won't catch fire.

Is it not turned on or is it that the display frequency is broken so that you can't turn it on! It will also cause you to not be able to catch fire.

It's that the pressure of the water is too low.

Then you won't be able to start the water heater.

It's just that the flow meter is broken.

Either the circuit board is broken, and these are the cases.

There are a variety of reasons why an electric water heater won't catch fire.

1. Is it not turned on, or is it that the display frequency is broken, so you can't turn it on! It will also cause you to not be able to catch fire2 or the pressure of the water is too low.

Then you won't be able to start the water heater.

3 is that the flow meter is broken.

4. Either the circuit board is broken, and these are the cases.

It may also be a malfunction of the solenoid valve, if you do not hear the magnetic absorption sound of the solenoid valve during the ignition, it is likely that it is due to the aging of the solenoid valve or a gas problem, or a circuit problem. We replace the solenoid valve or gas cylinder according to the specific reason, and if it is a problem with the control circuit, we can ask a professional to repair it.

It could also be an electrical ignition failure. If there is no electric spark or ignition sound when the water heater is ignited, then it may be due to the failure of the electric igniter. You can check whether there is a problem with the igniter or controller first, and if so, replace or repair it according to the situation.

It could also be a problem with the ignition porcelain needle. If there is no electric spark and ignition sound when the water heater is ignited, it may also be because of the ignition porcelain needle, you can check whether the porcelain needle is out of position or aging, and correct or replace it in time.

Clause. First, solenoid valve failure, this is a very common kind of failure, usually solenoid valve failure includes two kinds, damage and aging, such as when ignition, can be ignited, but will immediately go out, damage is simply not.

Clause. Second, the power problem, strictly speaking, this is not a problem, as long as you pay attention to it, but this is a problem that people are easy to ignore, this is very simple, you only need to check whether the AC power plug indicator is on. Clause.

Third, the water pressure problem, when the water pressure is too low, the water heater often can not start normally, of course, there will be a filter screen at the water inlet of the water heater, if the blocked water can not flow normally, it will not be lit, then as long as it is cleaned up.

1. The tympanic membrane in the water-gas linkage valve is aging or damaged, and the micro switch cannot be pushed; Clause.

Second, the micro switch is broken.

Clause. Fifth, the gas type does not match, this must be paid attention to, generally the water heater will be marked on which is liquefied gas, which is natural gas, sometimes it may be wrong, such as the liquefied gas should be connected to the natural gas, then only need to correct and reconnect.

Clause. 6. The valve seal is damaged, mainly because the water heater is easy to be corroded by gas if it has been used for a long time, and then it swells, so the parts must be replaced.

Clause. 7. The smoke pipe cannot be exhausted normally This is a problem that is easy to ignore, and there is no problem in itself, mainly including two forms: first.

1. If the smoke pipe is blocked, you only need to clean the blockage in the smoke pipe to ensure that it is unobstructed; Clause.

Second, the smoke pipe is too long, which is not conducive to the emission of smoke.

Clause. 8. The ignition switch resistance becomes larger or the contact is poor, and the ignition switch resistance becomes larger, which will lead to a decrease in the amount of power flowing into the battery, the current is small, and the magnetic attraction is naturally small, so the magnetic attraction cannot be turned on, resulting in no ignition.

Clause. 9. If the magnetic suction is broken or there is dirt in it, and if the magnetic suction is broken, the gas will not be able to come out, and it will also cause it to be unable to ignite. Clause.

10. The hot and cold water switch is in poor contact, the hot and cold water switch is directly connected to the ignition switch, and if the hot and cold water switch is bad, it will also cause the water heater to not ignite.

Through the above ten methods, you can find out the reason why the water heater does not catch fire, and solve it according to the introduced methods.

The problem with the highest fault rate of gas water heater is that the gas water heater cannot catch fire, of course, it is a strong exhaust type, and the phenomenon of failure has the exhaust fan rotating normally, but there is no sound of electric spark ignition; There was the sound of electric sparks, but they couldn't be ignited, and some turned on and didn't even react at all. These are the detailed phenomena that usually manifest when a water heater does not catch fire. Let's take a look at the reasons for this with China Lianbao.com, understand why the gas water heater can't catch fire, and then "prescribe the right medicine".

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.

Solenoid valve fault: if only the ignition sound is heard at the time of ignition, and there is no solenoid valve "click" magnetic absorption sound, it may be that the solenoid valve is damaged or aging, and the solenoid valve is aging, which will be uncontrollable. Before confirming the quality of the solenoid valve, it is necessary to confirm whether the ignition control circuit can be normal, if there is a problem, the solenoid valve can not be controlled.

Ignition fault: If one of the pulse igniters and controller fails, the water heater will not start.

Ignition needle or induction needle problem: the ignition needle deviation can be changed or the ignition needle can be placed correctly; If the aging problem of the induction is solved, just polish the induction and put it away.

Water pressure problem: The filter screen at the water inlet is infarcted and the water cannot flow normally, so it can be liquidated and cleaned.

Water-air linkage installation fault: the tympanic membrane in the water-air linkage valve is aging or damaged, and the micro switch cannot be promoted; The micro switch is broken.

The smoke pipe does not vent properly. There is an infarction in the smoke pipe, and the smoke pipe is too long and not properly installed. Please refer to the instructions for double-layer smoke pipe installation of balanced water heaters.

One of the reasons why the water heater won't catch fire: power supply problems.

The solution for the water heater not to catch fire: Check whether the AC power plug indicator is on, and first rule out the problem of the power supply part.

The second reason why the water heater cannot catch fire: the solenoid valve is faulty.

The solution to the water heater can not catch fire: if only the ignition sound is heard when ignition, and there is no solenoid valve "click" magnetic absorption, it may be that the solenoid valve is damaged or aging, and the solenoid valve is aging, and it will be uncontrollable. It may also be that the gas pressure is too high or too low, and the water heater that uses cylinder gas will have the output pressure of the cylinder pressure reducing valve is too high or too low, and the water heater cannot be ignited when using it; It is more likely that the solenoid valve has dirt. The solenoid valve cannot be overgased, and the gas (natural gas, liquefied petroleum gas, artificial gas) cannot come out, and cannot come out, so that the ignition cannot catch fire.

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.

1.Pulse failure, there are three outgoing wires in the pulse, (usually red, yellow and black) connected to the solenoid valve, there is a problem with the electric board inside, such as the water heater you buy is old-fashioned (produced before 03 years), the pulse will not be broken, and the pulse fault can be eliminated.

2.Solenoid valve failure. If the solenoid valve is broken, it will not catch fire. If the maintenance master has good skills, he can modify it well. But you can't cancel the solenoid valve, that's very dangerous.

3.If the rubber ring of the water vapor linkage valve is damaged, the rubber ring can only be replaced. You can also make rubber rings, but it also depends on whether the master has experience.

4.If the pressure reducing valve fails and the pressure of the pressure reducing valve is too large, it will also cause the solenoid valve of the water heater to not open, and the air will not be supplied.

You can determine what's broken, you turn off the gas, you pull the pipe off, you can call someone to turn the water on and off over there, you can listen to the sound to determine what the cause is.

1.If you can hear a knock when the pulse ignition is delayed for 1 second, it means that your pulse and solenoid valve are good.

2.If it does not sound, there will be two situations, the pulse cannot open the solenoid valve and the solenoid valve coil will burn.

3.If all of the above is normal, the pressure pressure at the outlet of the pressure reducing valve is too high.

There may be a problem with the battery, it is recommended to replace the battery! If it doesn't work, it is recommended to contact professional after-sales for maintenance!
