What is the Heavy cycle used for?
This program is intended for pots, pans, casseroles and sturdy tableware with baked-on, dried-on or greasy food soil.
It generally uses a more intensive wash pattern, hotter water or additional wash and rinse activity than a Normal cycle. That extra cleaning action explains its longer published time and higher possible water use.
Choose another cycle for: Fragile glassware, lightly soiled dishes or items that are not dishwasher-safe.
What this means for your load
For hard-to-clean items; soil and incoming water temperature affect duration. Check the appliance display for its current estimate.
Published water use: 7.75 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: Incoming water temperature, soil level, added sanitation and extra-dry options can extend the displayed time.

When will it finish?
This variable program depends on the stored cycle, options or sensed load. Use the appliance's current displayed estimate.
Estimated energy and local cost
This range is calculated from the documented cycle characteristics and appliance type. It is deliberately shown as a range because load conditions, temperature selections, sensors and options change consumption.
