Reasons why the gas water heater cannot ignite

A gas water heater is an appliance that uses gas as raw material. Its main purpose is to heat cold water into hot water by using gas. This method is very simple and practical. The gas water heater takes up very little space and is suitable for families with small spaces. Gas water heaters can also break down sometimes, so what is the reason why the gas water heater cannot ignite?

Many people always encounter this situation when using gas water heaters: no matter how hard they try, the water heater just won’t ignite. So we want to know the reason why the gas water heater cannot ignite. We asked professionals to introduce this issue to everyone. There are several reasons why the gas water heater cannot ignite.

1. Battery problem: If the water heater uses batteries, first check whether the batteries are too old. Insufficient voltage may also cause the water heater to fail to ignite.

2. Solenoid valve failure: If only the ignition sound is heard during ignition, but there is no solenoid valve "click" magnetic suction sound, the solenoid valve may be damaged or aged. An aged solenoid valve will be out of control. It can be attracted at the beginning of ignition and ignite the fire, but then it closes and extinguishes the flame again. Before confirming whether the solenoid valve is good or bad, confirm whether the ignition control circuit is normal. If there is a problem, the solenoid valve cannot be controlled to be attracted.

3. Ignition failure: If either the pulse ignition or the controller fails, the water heater cannot start.

4. Problems with the ignition needle or sensor needle: If the ignition needle is misaligned, you can replace it or put it correctly; if it is an aging problem of the sensor, just polish the sensor and put it back properly.

5. Water pressure problem: The filter at the water inlet is clogged, causing water to not flow through normally. Just clean it.

6. Water-gas linkage installation failure: The tympanic membrane inside the water-gas linkage valve is aging or damaged and cannot push the micro switch; the micro switch is broken.

7. The smoke pipe cannot exhaust normally: the smoke pipe is blocked, clear the blockage in the smoke pipe. The smoke pipe is too long and is not installed correctly. Please refer to the instructions for double-layer smoke pipe installation of balanced water heaters.
