The thermostat is disconnected, and the heating pipe of the electric water heater is provided with an anti-dry-burning thermostat. When the thermostat is disconnected, the electric heating tube is open and needs to be reset manually. You can measure it with a multimeter. There is electricity in the front stage of the thermostat and no electricity in the back stage, which means that the thermostat has jumped. Press the reset button to restore.

Relay failure. If there is no electricity in the front stage of temperature control, it should be that the relay is broken. It is necessary to remove the control panel and replace the relay.
The resistance wire in the heating pipe is broken.
