Safety first: Unplug the unit and close the water supply tap immediately to prevent flooding.

Steps to check:

Inspect the water level sensor: Locate the water level sensor or float assembly in the reservoir. Ensure it moves freely and is not obstructed by scale, slime, or debris. Clean with warm water and a mild descaler if necessary.
Check the drain path: Verify that the internal drain hose and external drain line are not kinked or blocked. Flush the line with warm water to clear any obstruction.
Test the inlet valve: With the unit unplugged and water supply turned off, disconnect the outlet side of the water inlet valve. Turn the water supply on briefly. If water leaks through the valve even without power, the valve is stuck open and must be replaced.
Reset and test: After cleaning and replacing any faulty parts, restore power and water, then run a test cycle while monitoring the fill level. The water should stop at the designed level without overflowing.

Warning: Persistent overfilling after these checks may indicate a control board fault; seek professional service.

Ice maker overfills with water; water spills into the bin or cabinet.
