How do I run the Clean Washer cycle and how often should I do it?

Run the Clean Washer cycle at least once per month or every 30 wash cycles, whichever comes first. To use it with affresh Washer Cleaner, place one affresh tablet directly in the empty washer drum (not the dispenser), select the CLEAN WASHER cycle, and touch and hold START. Do not place any garments or other items in the washer during this cycle, and do not interrupt the cycle for best results.
