Wanjiale gas water heater can t turn on the hot water heater can t catch fire, and the bathroom is f

Gas water heaters that can't catch fire can be divided into no ignition sound and no ignition and no ignition sound when there is a little fire.

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, 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.

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 kitchen faucet has a small amount of water output, try changing the faucet.
