During the operation of the electric water heater, the power indicator keeps flashing because the power supply is not in place or the operation is improper.
On the premise that the water temperature reaches the set pump opening temperature, the electric water heater stops replenishing water when the water level reaches the high level, starts replenishing water when the water level is lower than the low level, and starts alarming when the water level is lower than the extremely low level.
Operate the manual water inlet button to start the water supply of the electric water heater. When the water level reaches the extremely low level, the alarm stops and the electric water heater starts to work.
Secondly, the heating rod stops heating when the water temperature reaches the set upper limit temperature, and starts heating when the temperature is lower than the set lower limit temperature.
Finally, the electric water heater is equipped with a leakage and short circuit device. If the circuit fails, the power supply will be automatically disconnected.
The working principle of all electric water heaters is the same. The cold water enters the bottom of the water storage tank by the pressure of the pipe network. There is a heating pipe in the tank. The temperature controller, timer, etc. control the heating pipe,
It may be that your indicator light is broken. Check whether it is heated. If it is heated, it will be OK!! If not, it will be repaired.
