How do I use the TumbleFresh™ option and how does it work?

The TumbleFresh™ option periodically tumbles the load after the end of the cycle for up to 6 hours to reduce humidity, and is activated by touching TumbleFresh before starting a cycle. Once turned on, it stays on for all future cycles until manually turned off, as the washer remembers the last on/off status. Note that the door will remain locked while TumbleFresh™ is active; to cancel the option and unlock the door, touch POWER. (Page 5)
