Condensation or water droplets forming on the inside of the glass door.

Safety: No internal electrical work is usually required. Unplug the unit if inspecting the door heater connections.

Steps:

• Check gasket: Inspect the door seal for gaps, tears, or hardened sections. Replace if it does not make full contact with the cabinet.
• Reduce humidity: If possible, reduce room humidity or move the cooler to a less humid location.
• Limit door openings: Minimize how often and how long the door is opened.
• Door heater (if equipped): Some Zanussi models have a low-wattage heater around the glass. If condensation is severe and persistent, have a technician check the heater circuit.

Note: Light condensation in very humid conditions can be normal and may not indicate a fault.
