What is the Sanitize cycle and how does it work?

The Sanitize cycle is designed to kill bacteria in clothing and is certified by NSF International to reduce 99.9% of bacteria on laundry. When selected, the temperature is automatically set to HIGH and the dry level is set to EXTRA DRY, and these default settings cannot be changed. Do not use this cycle with delicate items or fabrics, and steam cannot be added to the Sanitize cycle. (Pages 21, 25)
