1. It may be that the heating system of the water heater is broken, and only the indicator light is on, but it does not heat.
2. It may be caused by the failure of the induction system inside the water heater.
3. It may be that there is no water in the water heater, the water at home is suddenly cut off or the tap water pressure is too low.
Suggested solution:
1 First of all, you need to check whether there is water in the water heater and turn on the tap to see if there is water flowing out. If there is no water flowing out, it proves that there is no water in the water heater or there is not enough water. At this time, you need to check whether the water is cut off at home. If the water is cut off, no special treatment is needed. If the water pressure is too low, it is necessary to install a booster valve or use a water heater at the wrong peak.
You need to contact professional maintenance personnel to check whether the heating system is damaged. If the heating system is damaged, it needs to be repaired, or the heating rod can be replaced directly.
3. If the thermostat is disconnected, you need to reset the thermostat manually.
