What is the Machine Clean cycle used for?
This maintenance program cleans the empty dishwasher rather than a load of dishes.
It circulates hot water through the tub and wash system to help remove grease, mineral film and odor-causing residue. Follow the manual regarding dishwasher cleaner and run it empty.
Choose another cycle for: Running with dishes, detergent combinations or cleaners not approved by the manufacturer.
What this means for your load

Published water use: 3.2 gal. This figure applies to the documented test conditions and may be a range when the appliance senses the load.
Why the time may change: Use the specified options and cleaner; changing them can alter the time or cleaning result.
