Display shows CF or CLEAN FILTER; ice production slows or stops.

Safety first: Unplug the Klarstein ice maker before cleaning.

• Remove and clean filter: If your model has a removable air filter behind the side or rear grille, slide it out and wash with warm soapy water. Dry completely before reinstalling.
• Vacuum condenser: Use a vacuum with a brush attachment to remove dust from the condenser coil.
• Clear vents: Ensure that intake and exhaust vents are not blocked by walls, curtains, or other appliances.
• Reset indicator: Follow the user manual to reset the CF/CLEAN FILTER reminder (often by holding a specific button for several seconds).

Maintaining clean airflow surfaces prevents overheating and extends compressor life.
