Interior humidity too low; corks appear dry on models with humidity control.

Safety first: Unplug the unit before accessing humidification components.

Steps:

• 1. Check water source: Fill the humidity tray or cartridge with clean water as per Liebherr instructions.
• 2. Verify installation: Ensure the tray is correctly positioned so air can pass over it.
• 3. Inspect door seal: Replace gasket if leaking, as excessive air exchange can lower humidity.
• 4. Humidification module: If humidity remains low despite correct setup, have the humidification module and sensor checked by a technician.
