How to Fix / Troubleshooting
Safety: Disconnect power before working on the heater circuit.
- Confirm lack of heating: Run a hot program and check if the water remains cold and H2 appears.
- Access heater assembly: Remove the lower front and bottom panels to reach the integrated heater/circulation pump.
- Test heater and NTC: Measure resistance of the heater and NTC sensor. Replace any component that is open, shorted, or out of specification.
- Inspect control board: If both heater and NTC are good, the control board may have a faulty relay and should be repaired or replaced by a professional.
