The water heater is running normally but the water is not hot?

1, maybe the thermostat of the water heater is broken. As a result, the water heater kept heating and the water temperature kept rising, which made the high temperature limit switch trip, so the water heater turned off the power and did not heat the water.

2. It may be that the heating rod of the water heater is damaged and loses its heating function.

3. It may also be caused by poor contact between plug and socket.

Suggested solution:

1. If there is something wrong with the thermostat, you can check whether the thermostat is open first. If the resistance measured by the multimeter shows infinity (normally 0) or there is no sound when turning the switch, it means that the thermostat is broken and needs to be replaced with the same model.

2. If the water heater is used for too long and the cleaning times are too few, then the heating rod will be damaged. If there is too much scale on the heating rod, it will not only slow down the heating speed, but also make the water heater consume more electricity. In this regard, it is necessary to clean the scale accumulated on the heating rod regularly, and if the problem still cannot be solved, replace it with a new heating rod.

3. It is risky to check the circuit problem, so it is necessary to check the damage of the power cord and the plug-in chip. We can repair it according to the instructions, and we need to pay attention to safety when handling it. If you can't solve it yourself, it is recommended to contact a professional for timely maintenance.
