How do I run the Clean Washer cycle to keep the inside of my washer fresh?

Select the CLEAN WASHER cycle with an empty drum, then add either an affresh® Washer Cleaner tablet directly into the drum (not the dispenser) or add liquid chlorine bleach to the MAX level in both the bleach and fabric softener compartments. Touch and hold START to begin the cycle, and do not interrupt it for best results. This maintenance procedure should be performed at a minimum once per month or every 30 wash cycles, whichever comes first. (Page 13)
