Possible Causes

Stuck water inlet valve, Faulty water level sensor, Float jammed in low position, Control board not stopping fill

How to Fix / Troubleshooting

Safety first: Unplug the unit and shut off water supply if plumbed-in. Mop up any spilled water.

Steps to correct overflow:

  • Inspect float and sensor: Ensure the float moves freely and is not obstructed by scale or debris.
  • Clean sensor area: Remove mineral buildup around the water level sensor.
  • Test inlet valve: If water continues to flow when the unit is off, the inlet valve is stuck open and must be replaced.
  • Replace faulty sensor: If the valve is controlled correctly but the unit still overfills, replace the water level sensor or float switch.
