Ice tray overfills with water, causing spillage or oversized ice blocks.

Safety first: Unplug the unit and turn off water supply if plumbed.

Steps to correct overfilling:

• Inspect valve: Check the water inlet valve for signs of sticking or leaking when de-energized. Replace if it drips continuously.
• Clean level sensor: Clean the water level sensor or float to ensure it moves freely and is not coated with scale.
• Check drain: Ensure the internal drain path from the tray is clear so excess water can return to the reservoir.
• Control board: If the valve is good but remains energized too long, the main control board may be faulty and require replacement.
