How often should I perform the washer maintenance procedure?

The washer maintenance procedure should be performed on a monthly basis using either one AFFRESH™ washer cleaner tablet or 2/3 cup of liquid chlorine bleach with the Clean Washer cycle to thoroughly clean the inside of the washer. To maintain washer freshness, always leave the door slightly open after each cycle to allow for better ventilation and drying of the washer interior. (Page 17)
