E09 error appears; ice level sensor does not detect ice correctly, causing overfilling or no ice production.

Safety first: Unplug the unit before working inside the ice bin area.

• Locate the ice level sensor: In many Weasy ice makers, an infrared emitter and receiver are mounted on opposite sides of the ice bin opening.
• Clean sensor windows: Use a soft cloth dampened with warm water to gently clean the sensor lenses. Remove any frost, mineral deposits, or grease.
• Check alignment: Ensure both sides of the sensor pair are firmly mounted and facing each other directly. Tighten any loose mounting screws.
• Inspect wiring: Follow the sensor harness back to the control board. Reseat the connector and check for pinched or broken wires.
• Test operation: After cleaning, restore power and start a cycle. Observe whether the unit now stops ice production when the bin is full and resumes when ice is removed.
• Replace the ice level sensor assembly (emitter/receiver pair or combined board) if cleaning and reseating do not clear E09.
