Common Issues That Require Professional Tankless Water Heater Repair

Tankless water heaters are reliable, but like any appliance, they can develop issues over time. Recognizing the signs of a problem early can save you from a complete system failure. If you notice any of the following, it’s a good indication that your unit needs professional attention.

We frequently diagnose and resolve a variety of tankless water heater problems, including:

No Hot Water or Lukewarm Water This is the most obvious sign of a problem. It could be caused by anything from a simple ignition failure to a more complex internal component issue. Our technicians can quickly find the source and restore your hot water.

Fluctuating Water Temperatures If your water temperature swings from hot to cold during use, it often points to a problem with the unit's flow sensor or a blockage. This inconsistency can be frustrating, but it is a repair we handle regularly.

Unusual Noises Loud humming, clicking, or banging sounds are not normal. These noises often indicate mineral and sediment buildup inside the system, a common issue in areas with hard water. A professional flush and service can resolve this.

Warning Lights or Error Codes Modern tankless heaters use error codes to signal specific malfunctions. Instead of guessing, let our technicians interpret these codes correctly to perform a precise and effective tankless water heater repair.

Low Water Pressure A sudden drop in hot water pressure can be caused by scale buildup constricting the flow of water through the pipes and heat exchanger. We can descale your unit to restore its original pressure and efficiency.
