How to solve the problem of natural gas water heater not heating

1. It may be that the power supply is not connected. Check whether there is a power outage at home, whether the socket is plugged in, whether the plugboard is powered on, etc.
2. It may be that the water heater is leaking electricity. The water heater has a leakage protection switch. After detecting the leakage, it will automatically cut off the power supply and check whether the circuit of the water heater is short-circuited.
3. It may be that the heating rod inside the water heater is severely scaled, which affects the heating efficiency, and needs to be cleaned with descaling fluid.
4. Or the heating rod is broken.
5. The thermostat of the water heater is broken, causing the water heater to not work properly and keeps heating. The thermostat of the water heater is broken and needs to be replaced with a new thermostat.
6. Check the temperature sensor of the water heater. If the thermostat is broken, replace the sensor with a new one.
