Possible Causes

Faulty water level sensor, stuck float, control board not stopping fill, misrouted water tube

How to Fix / Troubleshooting

Safety first: Unplug the unit and dry any spilled water before proceeding.

  • Inspect float and sensor: Ensure the float in the reservoir moves freely and is not stuck in the low position.
  • Check water tube position: Verify the water outlet tube is correctly aimed at the tray and not dislodged.
  • Clean scale: Remove mineral deposits from the float and sensor area that may prevent proper operation.
  • Replace sensor or float: If overfilling continues, replace the water level sensor/float assembly.
  • Control board: Persistent overfill with a new sensor may indicate a control board fault.
