E05 error, ice bin overfills or ice production stops with bin not full

Safety: Disconnect power before cleaning or adjusting sensors.

Steps:

• Locate sensors: In many Neff ice makers, the ice level is detected by an infrared sensor pair on opposite sides of the bin or a sensor above the bin.
• Clean lenses: Use a soft cloth slightly dampened with warm water to clean the sensor windows. Do not use abrasive cleaners or soak the electronics.
• Check alignment: Ensure the emitter and receiver are facing each other correctly and not blocked by ice, labels, or bin misplacement. Re-seat the ice bin fully.
• Inspect wiring: Check the harness from the sensor to the control board for damage or loose connectors.

Next step: If E05 persists after cleaning and alignment, the ice level sensor module is likely defective and should be replaced.
