5. Maintenance and Care
Regular cleaning and maintenance will ensure your appliance operates efficiently and extends its lifespan.
Cleaning the Interior:
- Unplug the appliance before cleaning.
- Clean the interior with a soft cloth, lukewarm water, and a mild, neutral detergent.
- Do not use abrasive cleaners, scouring pads, or solvents.
- Remove shelves, drawers, and door bins for thorough cleaning.
- Dry all parts thoroughly before placing them back.
Cleaning the Exterior:
- Wipe the exterior surfaces with a soft, damp cloth. For black stainless steel, use a specialized cleaner if necessary to maintain its anti-fingerprint finish.
- Clean the door seals regularly to ensure a tight seal and prevent energy loss.
Condenser Coils:
Periodically (at least once a year), clean the condenser coils at the back of the appliance with a soft brush or vacuum cleaner. This improves energy efficiency.
Defrosting:
Thanks to NoFrost technology, manual defrosting of the freezer compartment is not required. The refrigerator compartment defrosts automatically.
