This reducesice production and shortens component life. Clean thecondenser at least every six months. Follow the stepsbelow.1. The washable filter on self-contained ice machinesis designed to catch dust, dirt, lint and grease. Thishelps keep the condenser clean. Clean the filter witha mild soap and water solution.2.
