E06 displayed, ice maker overfills with water or water spills into bin

Safety first: Disconnect power and close the water supply valve to prevent further flooding.

Steps to resolve:

• Remove excess water: Mop up any standing water in the bin and cabinet. Dry the area thoroughly to prevent electrical shorts.
• Inspect water level sensor: Many De Dietrich ice makers use a float switch or electronic water level sensor in the reservoir. Check that the float moves freely and is not obstructed by scale or debris.
• Clean reservoir: Remove the water reservoir cover and clean mineral deposits with a mixture of warm water and food-safe descaler. Rinse thoroughly.
• Check inlet valve operation: With the unit powered and water supply on, listen to the water inlet valve during fill. If water continues to flow after the fill cycle should end, the valve may be mechanically stuck open and must be replaced.
• Inspect level tube: If a pressure tube is used, ensure it is not blocked or kinked.

Warning: Persistent overfilling after cleaning and valve replacement indicates a control board issue. In that case, contact a qualified technician to avoid repeated flooding.
