Wan Jiale TM55 strong exhaust water heater won't catch fire, but it squeaks when it is turned on, but it doesn't burn and there is no flame at all. What happened? Heroes, take a look at it for me.

First, check whether the power supply has electricity, whether the air valve is in the open state, and see if the microswitch can be opened normally.

Secondly, let's see if the fan works. If there is work, you will hear the sound of a fan, forcing the exhaust to clean before.

The third is to see if the wind pressure works. If so, you can definitely hear the working sound of the solenoid valve. If not, what are the above questions?

If there is no flame and no ventilation at all, you have to see if there is a sound of reaching out. If there is an electromagnetic needle valve that can be broken, there may be something wrong with the control panel. If so, you should contact the after-sales professionals! ,

Working principle:

After water supply, the water pressure pushes the water-gas linkage valve, and then starts the fan, and then the high-pressure bag. The electromagnetic valve is opened during ignition, the induction needle senses the flame after ignition, the ignition of the high-voltage bag stops, the electromagnetic valve remains open, and the machine works normally.
