How do I clean the inside of my washing machine to prevent odors?

Use the Clean Washer with AFFRESH™ cycle once a month to keep the inside of your washer fresh and clean. Add one AFFRESH® washer cleaner tablet to the empty washer drum (or 2/3 cup of liquid chlorine bleach to the bleach dispenser compartment), then select the Clean Washer with AFFRESH™ cycle and press START/PAUSE. After the cycle is complete, leave the door slightly open to allow for better ventilation and drying of the washer interior. (Page 20)
