The indicator light is powered by the modified computer board. Usually, there is a transformer on the computer board. After the transformer is damaged, the water heater does not work and the indicator light does not light up. Need to replace a new computer motherboard.
When the water heater is plugged into the power supply, it is not bright, or it may be the action of the anti-dry burning controller. There is an anti-dry burning controller on the water heater, which is generally designed at 80℃. If the temperature of the water heater exceeds 80℃ during heating, the anti-dry burning controller will brake to cut off the power supply, resulting in no electricity.
It may also be that the electric water heater is powered on when there is no water, and the burning of the heating tube of the water heater will lead to the power failure of the water heater.
Damage to the thermostat will also lead to the situation that the water heater is plugged in without electricity and lights. The thermostat is broken. Generally, a thermostat is connected in series in the circuit of the heating tube of the electric water heater, and some water heaters are connected in series in the power inlet line, so the indicator light of the electric water heater will not light up.
