Display shows F11; water may leak in the ice maker area or no ice is produced despite water supply.

Safety first: Unplug the refrigerator and close the external water supply valve before working on water components.

Step-by-step:

• Check water supply: Confirm that the household water valve is open and that the supply hose to the refrigerator is not kinked.
• Inspect for leaks: Look behind and under the refrigerator for signs of water leakage around the inlet valve.
• Check fill tube: Access the ice maker area and inspect the plastic fill tube for ice blockage. If frozen, thaw gently with warm air.
• Replace water filter: If equipped, replace the Liebherr water filter, as a clogged filter can reduce flow.
• Test inlet valve (advanced): With power disconnected, remove the rear lower cover and locate the ice maker inlet valve. Check coil resistance with a multimeter; an open coil indicates a bad valve.
• Replace valve if faulty: Install a new Liebherr ice maker water inlet valve, reconnect water lines securely, and check for leaks after restoring water and power.
