Maintenance method of flameout of electric water heater created by Bosia —— Causes of flameout of electric water heater

1, the power supply problem caused by the water heater not firing.

Solution of water heater not burning: check whether the indicator light of AC power plug is on, and first eliminate the problem of power supply.

2. The solenoid valve that caused the water heater not to catch fire failed.

Solution to the problem that the water heater can't ignite: A. If only the ignition sound is heard during ignition, the solenoid valve has no magnetic sound absorption, which may be that the solenoid valve is damaged or aging, and the solenoid valve will be out of control. You can smoke when you start the ignition, but then it will be closed and turned off; It is also possible that the gas pressure is too high or too low, and the output pressure of the cylinder pressure reducing valve is too high or too low, which will cause the water heater to catch fire; It is more likely that there is dirt on the solenoid valve.

B the solenoid valve can't be emptied, and the gas (natural gas, liquefied petroleum gas and artificial gas) can't get out, so it won't catch fire.

C first confirm whether the igniter control circuit is normal, and then confirm whether the solenoid valve is good or bad. If there is a fault, the solenoid valve can't be controlled to pull in.

The reason why the water heater can't catch fire is that the electric igniter is faulty.

Solution to the problem that the water heater can't catch fire: If one of the pulse igniter and controller is faulty, the water heater can't catch fire.

4. The reason why the water heater can't catch fire is the ignition porcelain needle or the induction porcelain needle.

Solution to the problem that the water heater can't catch fire;

A it is very difficult to ignite when the ignition needle is deviated or aged, so it can be replaced or placed correctly;

B. Induction aging can be accomplished by grinding and placing induction needles (so that the flame can fully burn the induction needles no matter whether it is a big fire or a small fire).

5. The water pressure problem of the water heater won't catch fire.

Solution to the problem that the water heater can't catch fire;

A. When the water pressure is low, the water heater cannot be started normally;

B. Because the filter screen of the water inlet is blocked, the water can't flow normally, so it can be cleaned;

6. The water heater can't catch fire because of the water-gas linkage fault.

Solution to the problem that the water heater can't catch fire;

A. The aging or damage of the eardrum in the water-gas linkage valve cannot push the microswitch;

B. The microswitch is broken.

7. The reason why the water heater can't catch fire is that the air source switch is not turned on or the air inlet filter screen is blocked.

Solution of water heater not burning: turn on the air source and clean the air inlet filter.

8. The reason why the water heater can't catch fire is that the gas types don't match.

Solution to the problem that the water heater can't catch fire;

For example, connect the liquefied gas water heater to natural gas and so on. In this case, it is necessary to replace the liquefied gas water heater with natural gas before it can be connected and used.

9. The reason why the water heater can't catch fire is that the valve seal rises after being corroded by gas.

The solution to the problem that the water heater can't catch fire: replace the parts.

10, the reason why the water heater can't catch fire is that the smoke pipe can't exhaust normally.

Solution to the problem that the water heater can't catch fire;

A. If the smoke pipe is blocked, clean the smoke pipe blockage;

B. The smoke pipe is too long and is not installed correctly;
