E14 displayed, ice maker cycles but ice cubes are irregularly shaped or fused together

Safety first: Disconnect power before accessing sensors or the evaporator plate.

Steps to correct ice shape:

• Clean evaporator plate: Mineral buildup on the evaporator plate can cause uneven ice release. Use a food-safe descaler and soft cloth to clean the plate thoroughly.
• Inspect water distribution: Ensure the water distribution tube or spray bar has all holes clear and is correctly positioned to cover the plate evenly.
• Check evaporator thermistor: Locate the evaporator temperature sensor clipped to or near the plate. Verify it is firmly attached and not corroded. Test resistance against De Dietrich specifications; replace if out of range.
• Reset control: After cleaning and sensor checks, perform a control reset (power off for 5 minutes, then restart) to clear any timing glitches.

Note: If irregular ice persists and sensors test correctly, the main control board may be mismanaging the harvest cycle and could require replacement.
