Why does the electric water heater that pumps water automatically stop at a little bit?

1. If heating stops automatically after starting, the reason is that the temperature value of the thermostat is too low, which is 1. 2. Aging of components leads to data failure or shutdown due to leakage failure.

Second, the working principle of electric water heater is:

The electric water heater is heated and unheated by the switch of the thermostat. The common concept of heat preservation is short-time heating. When heating, after the thermostat circuit is turned on, if the water temperature is lower than 50℃ (the critical temperature set by most brands), the thermostat will automatically turn on and the water heater will start heating. When the water temperature is higher than the preset temperature of the water heater (75℃ ~ 85℃ for most brands), the thermostat is closed and the water heater stops heating. The so-called heat preservation.
