The water heater burns for a few seconds and turns off automatically

Why does a water heater burn for 1-3 seconds and turns off automatically?

After the machine is ignited, it still turns off after a few seconds of ignition, which is a long ignition failure, usually because the ignition feedback needle or controller has failed. The principle is that when the machine starts ignition combustion, the flame detector pin of the machine will generate a signal and transmit it to the controller after it comes into contact with the flame. As soon as the controller receives the signal, it determines that the machine is ignited and burned successfully, and the ignition system is turned off and enters the normal working state. Once the flame leaves the feedback signal of the feedback needle, the machine will automatically shut down, which is the unexpected flameout protection function of the water heater. So you first check whether the contact between the ignition feedback needle and the flame and the link to the controller is good, and then consider whether it is a fault of the controller.
