Many people will encounter the problem that the gas water heater can't start, but many people don't know the reason why it can't start. If you happen to encounter the situation that the gas water heater can't start, don't worry first. Let me popularize the ten possible causes of the water heater's failure and the ways to solve them

many people will encounter the problem that the gas water heater can't start, but many people don't know the reason for it. If you happen to encounter the situation that the gas water heater can't start, don't worry first. Let me popularize the ten possible causes of the water heater's failure and the ways to solve them

one of the reasons why the water heater can't fire: power supply problem

solution to the problem: check whether the indicator light of the AC power plug is on, and first eliminate the problem of the power supply part of the power supply

the second reason why the water heater can't start fire: solenoid valve failure

solution for the water heater can't start fire: if only the ignition sound is heard when the ignition is on, there is no solenoid valve “ Da ” Magnetic sound absorption may be caused by the damage or aging of the solenoid valve. The aging of the solenoid valve will be uncontrolled. It can be pulled in at the beginning of the ignition, so that it can catch fire, but then it closes and stalls; It may also be that the gas pressure is too high or too low, and the output pressure of the cylinder pressure relief valve will be too high or too low when using the water heater with cylinder gas, and the water heater cannot catch fire; More likely, because the solenoid valve has dirt, the solenoid valve can't pass through the gas, and the gas (natural gas, liquefied petroleum gas, artificial gas) can't come out, so it can't ignite. Before confirming the quality of the solenoid valve, confirm whether the control circuit of the igniter is normal. If there is a fault, the solenoid valve cannot be controlled to pull in

the third reason why the water heater can't ignite: the electric igniter fails

the solution of the water heater can't ignite: if one of the pulse igniter and the controller fails, the water heater can't ignite

the fourth reason why the water heater can't ignite: the problem of ignition porcelain needle or induction porcelain needle

the solution of the water heater can't ignite:

a. it's very difficult to ignite when the ignition needle is out of position or aging, so it can be replaced or placed correctly

b. for induction aging, you can polish the induction and place it well (so that the flame can fully burn the induction needle no matter the fire is large or small)

the fifth reason why the water heater can't start: the problem of water pressure

the solution of the water heater can't start:

a. the water heater can't start normally when the water pressure is low

b. the filter screen at the inlet is blocked, which makes the water unable to flow normally. Clean it up

the sixth reason why the water heater can't fire: the failure of the water gas linkage device

the solution of the water heater can't fire:

a. the tympanic membrane in the water gas linkage valve is aging or damaged and can't push the microswitch

b. the microswitch is broken

the seventh reason why the water heater can't start fire: the air source switch is not opened or the air inlet filter screen is blocked

the solution to the water heater can't start fire: turn on the air source and clean the air inlet filter screen

the eighth reason why the water heater can't start fire: the gas type is inconsistent

the solution for the water heater can't start fire: for example, connect the liquefied gas water heater to natural gas. In this case, the liquefied gas water heater can be connected and used only after it is changed to natural gas

the ninth reason why the water heater can't start: the valve seal rises after being corroded by gas

the solution for the water heater not to ignite: replace the parts

the tenth reason why the water heater can't start the fire: the smoke pipe can't exhaust normally

the solution of the water heater can't start the fire:

a. the smoke pipe is blocked, clean up the blockage of the smoke pipe

b. the smoke pipe is too long and not installed correctly

summary: don't worry if the gas water heater can't start. Don't rush to send it for maintenance. First check according to the above ten situations. Maybe it's just some small problems that you can solve by yourself
