How often should I clean the inside of my washer and what should I use?

You should perform the washer maintenance procedure on a monthly basis using the Clean Washer cycle. Add ²⁄₃ cup (160 mL) of liquid chlorine bleach to the bleach compartment with no detergent, select the CLEAN WASHER cycle, and press START. Additionally, leave the door slightly open after each cycle to allow for better ventilation and drying of the washer interior. (Page 18-19)
