Liebherr appliance shows F6 and ice maker does not operate; other freezer functions normal

Safety first: Unplug the appliance before accessing control boards or wiring.

• Power cycle: Disconnect the appliance from power for at least 10 minutes to fully discharge the electronics, then reconnect and check if F6 clears.
• Inspect harness: Access the rear or top panel (depending on model) to locate the harness running from the main control board to the ice maker. Look for pinched, cut, or abraded wires.
• Check connectors: Unplug the harness connectors at both the main PCB and the ice maker. Inspect for bent pins, corrosion, or moisture. Clean lightly with electrical contact cleaner if available and reconnect firmly.
• Check for moisture intrusion: Look for signs of condensation or water near the connectors or control board. If present, dry the area thoroughly and correct any door seal or insulation issues causing condensation.
• If F6 remains: Either the ice maker module or the main control board is not communicating correctly. Diagnosis typically requires Liebherr diagnostic tools; contact an authorized service technician for board-level testing and replacement.
