E8 displayed; ice size is inconsistent or unit stops with ice stuck on evaporator.

Safety first: Unplug the ice maker before touching the evaporator or sensors.

Steps to address E8:

• Clean evaporator: Use a soft cloth and a mixture of water and white vinegar to gently clean the metal evaporator fingers or plate. Remove any scale or slime.
• Locate thickness sensor: Some Silonn models use a metal probe or lever that detects ice thickness during harvest. Ensure it is not bent or coated with mineral deposits.
• Adjust if applicable: If your model has an adjustable ice thickness sensor, follow the user manual to set it to the factory position.
• Inspect wiring: Check the sensor wiring harness for damage and ensure the connector is secure on the control board.
• Test cycle: Plug in the unit and run several cycles. Observe whether ice releases properly and whether E8 reappears.
• Replace sensor or board: If cleaning and adjustment do not help, replace the ice thickness sensor. Persistent issues after sensor replacement may indicate a faulty main control board.

When to call a professional: If you are unsure which sensor your model uses or how to adjust it, consult a technician.
