Ice maker displays an ice level sensor error; the unit stops making ice even though the bin is empty.

Safety first: Unplug the ice maker before removing interior covers.

Steps to check:

• Clean the sensor area: Many Grundig ice makers use an optical sensor near the top of the bin. Wipe the sensor windows with a soft cloth and warm water to remove frost, scale, or film.
• Check alignment: Ensure the emitter and receiver modules are facing each other correctly and are not knocked out of position by ice or bins.
• Inspect wiring: Follow the sensor harness back to the control board. Confirm connectors are fully seated and wires are not pinched.
• Test operation: After cleaning, restore power and empty the bin. The unit should resume ice production. If the error persists, replace the ice level sensor assembly.

Tip: Avoid storing non-ice items in the bin, as they can block or damage the sensor.
