Tankless Water Heater Repair in North Charleston, SC

Is Your Tankless Water Heater Acting Up? Common Signs You Need Repair

Recognizing the early signs of a malfunctioning tankless water heater can prevent minor issues from escalating into major problems. If you notice any of the following, it's time to consider professional repair:

No Hot Water or Intermittent Hot Water

The most obvious sign of a problem is a complete lack of hot water or water that cycles between hot and cold. This could indicate issues with the unit's ignition, flow sensor, or a buildup of minerals affecting the heat exchanger.

Fluctuating Water Temperature

If your hot water temperature isn't consistent, providing bursts of hot followed by lukewarm water, it often points to a faulty flow sensor, scaling within the unit, or issues with the gas valve modulation.

Error Codes Displayed

Modern tankless water heaters are equipped with diagnostic systems that display error codes on the unit's control panel. These codes are invaluable for pinpointing specific malfunctions, such as ignition failures (e.g., E1, F7), flow issues (e.g., E2, F4), or temperature sensor problems (e.g., E3, F5). Our technicians are proficient in interpreting these codes and addressing the underlying causes.

Reduced Water Flow or Pressure

Mineral buildup (scaling) inside the heat exchanger can restrict water flow, leading to noticeable drops in water pressure from hot water faucets. This is particularly common in areas like North Charleston, which can have hard water.

Unusual Noises

Strange sounds like banging, popping, hissing, or gurgling emanating from your tankless unit are clear indicators of internal issues. Banging often signals air in the lines or mineral deposits, while hissing can suggest a leak.

Visible Leaks or Drips

Any water pooling around or dripping from your tankless water heater requires immediate attention. Leaks can result from loose connections, worn seals, or corrosion, potentially causing significant water damage and impacting the unit's performance.

Pilot Light or Ignition Issues (for Gas Units)

If your gas tankless water heater's pilot light won't stay lit or if the burner repeatedly fails to ignite, it could be due to a faulty igniter, thermocouple, gas supply problem, or issues with the ventilation system.
