Refrigerator shows F7; ice maker or ice compartment may not maintain correct temperature.

Safety: Unplug the appliance before removing ice maker covers or panels.

Steps:

• Check ice production: Note whether ice cubes are small, hollow, or not produced at all. This helps confirm a temperature control issue.
• Locate ice sensor: On Miele models with dedicated ice compartments, the sensor is often clipped near the ice tray or in the ice storage area. Remove the ice bin and any covers to access it.
• Inspect wiring: Look for broken or pinched wires, especially where they pass through the door hinge area.
• Test sensor: Disconnect the sensor and measure resistance. Compare to Miele specifications for the measured temperature. Replace if out of range.

If sensor and wiring are intact, the ice control electronics or main board may be faulty and require professional diagnosis.
