How to Repair Tankless Water Heaters
Here are some solutions to common problems with tankless water heaters:
No Hot Water
If you’re not getting any hot water from your tankless water heater, there could be a few reasons for this. First, check to make sure that the water heater is receiving power and that the circuit breaker hasn’t tripped. If power is not the issue, the problem may be with the heating element or the flow sensor. In this case, you’ll need to contact a professional to repair your tankless water heater.
Fluctuating Water Temperature
If your tankless water heater is producing water that fluctuates between hot and cold, there may be an issue with the flow sensor or the water pressure. Try cleaning the filter on the water inlet and outlet to improve water flow. If this doesn’t work, contact a professional for further diagnosis and repair.
Water is Too Hot
If your tankless water heater is producing water that is too hot, you may need to adjust the temperature settings on the unit. Refer to the owner’s manual for instructions on how to do this. If the temperature settings are not the issue, then the problem may be with the thermostat or the temperature sensor. In this case, you’ll need to contact a professional to repair your tankless water heater.
Water is Not Hot Enough
If your tankless water heater is not producing water that is hot enough, you may need to adjust the temperature settings on the unit. Refer to the owner’s manual for instructions on how to do this. If the temperature settings are not the issue, then the problem may be with the heating element or the gas burner. In this case, you’ll need to contact a professional to repair your tankless water heater.
Strange Noises
If your tankless water heater is making strange noises, such as gurgling or popping sounds, there may be air in the system. Try purging the air from the system by turning off the unit and opening the hot water faucet. If this doesn’t work, there may be an issue with the heating element or the gas burner. In this case, you’ll need to contact a professional to repair your tankless water heater.
Leaking Water
If your tankless water heater is leaking water, turn off the unit and the water supply immediately. Check the connections on the unit and tighten any loose fittings. If the leak continues, there may be a problem with the unit’s internal components, such as the pressure relief valve or the heat exchanger. In this case, you’ll need to contact a professional to repair your tankless water heater.
