What is the Wrinkle Control feature and how does it work?

The Wrinkle Control feature adds up to 90 minutes of heat-free, periodic tumbling at the end of a cycle to prevent wrinkles from forming if you are not ready to remove the load immediately. It can be selected as a special setting and runs without heat. You can also select the Wrinkle Control cycle if loads come out wrinkled due to not being removed promptly. (Page 5, 7)
