What’s wrong with the water heater only lights on but not heating? How to solve and deal with this situation
Why does the water heater only turn on but not heat it? What is the reason for this? Why does this happen? Let’s take a look together and see what is causing it.
Reason why the water heater only lights on but not heats:
1error setting
If our water heater can turn on normally, then we need to pay attention here that may be our setting error, which caused our water heater to fail to heat. In this case, we have to check whether the temperature is set correctly. If the temperature is set too low, the water temperature of our water heater will not rise, which will cause our water heater to fail to heat normally.
2Damaged heating element
This is something we need to pay attention to. If our water heater suddenly fails to heat, it may be that the heating element of our water heater has failed. In this case, we need to find a professional to repair and deal with it. If we replace it ourselves, other problems may arise, so we are not recommended to replace it ourselves.
3power failure
If our indicator light is on, it means that there is no problem with our water heater plug and accessories, and the problem is the internal power supply. In this case, we also need a professional master to carry out maintenance. It is not so easy for us to operate it ourselves. At the same time, some other problems may arise if we are not professionals operating it.
4The internal fuse blew
When the temperature of the water heater reaches a certain saturation point, our water heater will not be heated again at this time. If we can manually restore the temperature controller, it means that our water heater has no problem. If it cannot be restored, it means that our water heater has experienced other conditions, such as the mentioned blown fuse. This situation requires professional personnel to operate and handle it.
If we encounter a water heater at home on but not heating it, we can investigate the reasons mentioned above. If we cannot handle it ourselves, we must find a professional to handle it.
