E11 error; unit may overfill or underfill the ice bin, or stop production prematurely.

Safety First: Turn off power. Remove ice from the bin to prevent spills and allow clear access to sensors.

Steps:

• Locate optical sensors: On many Café ice makers, an infrared emitter and receiver are mounted on opposite sides of the ice bin opening.
• Clean sensor windows: Use a soft, lint-free cloth slightly dampened with warm water to clean the sensor lenses. Do not use abrasive cleaners.
• Check alignment: Ensure both sensor modules are firmly mounted and facing each other directly. Adjust mounting screws if needed.
• Inspect wiring: Follow the sensor harnesses to the control board. Reseat connectors and check for pinched or broken wires.
• Replace optical sensor kit: If cleaning and alignment do not resolve E11, replace the Café optical ice level sensor kit (both emitter and receiver) according to the service instructions.
• Test operation: Restore power and verify that ice production stops when the bin is full and resumes when ice is removed.
