Long Cycle Times on Whirlpool Dishwasher

Dishwasher cycle time is anywhere from 1.5 to 4 hours long. The time depends on several factors, including cycle selection, water temperature, dirtiness of the dishes, and if heat dry was selected.

Cycles and Modifiers

Energy efficiency is gained by extending cycle time and reducing the amount of wattage and water used during the dishwasher's cycle. Efficient dishwashers run longer to save water and energy, just as driving a car slower saves on gas. If you need your dishes done sooner, you can use the 1-hour wash cycle. Using the 1-hour wash cycle will reduce drying performance and energy efficiency.

Review your dishwasher's cycle guide for estimated time.

How Dirty are the Dishes?

The dishwasher "senses" wash water quality during a series of pauses in the wash cycle. The sensor monitors water temperature and the amount of soil and detergent appearing in the wash cycle for the best wash. Lightly soiled dishes use less water and energy. Heavily soiled dishes will get more water and increased temperature and wash time. This dishwasher will automatically adjust the sensor approximately once a year to your water quality.

Water Temperature

To minimize cycle time, run the hot water faucet at the sink closest to the dishwasher until the water is hot; as part of normal operation, the dishwasher pauses two or three times during the cycle to heat the water to the proper cleaning temperature. Once the temperature is met, the cycle will advance. Having hot water enters the dishwasher right when the cycle begins can eliminate the need for long heating pauses, decreasing the time it takes to complete the cycle.

The water should be 120°F as it enters the dishwasher for best results. Loads may not wash as well if the water temperature is too low. Water that is too hot can make some soils harder to remove and cause certain detergent ingredients not to function.

What type of detergent should I use?

High-quality pre-measured tablets and packs are recommended for improved performance.

Quality tablets and packs have been proven better than powder, liquid, or gel detergents at reducing filming on dishes. Using tablets and packs over time will start to reduce or eliminate white film. They are suitable for all water hardness and soil levels. Also, by using rinse aid, you can minimize the repeat buildup of the white film (not all packs and tablets contain rinse aid). Always place pre-measured detergents in the main compartment and close the lid.

The Pre-Wash indicator on the dispenser lid is for customers who use powder or gel detergent and wish to add an amount of detergent to the Pre-Wash cycle. The volume of detergent added here is approximately eight cubic centimeters if filled full and level. Any detergent added here would be immediately added to the wash when the cycle starts versus detergent inside the dispenser, which is added during the main wash cycle.

NOTE: Follow the instructions on the package when using other dishwasher detergent types.

Use automatic dishwasher detergent only. Add detergent just before starting a cycle.
Fresh automatic dishwasher detergent results in better cleaning.
Store the detergent in a tightly closed container and place it in a cool, dry place.
Extremely hard water mineral deposits (15 grains per U.S. gallon or more) can damage your dishwasher and make good results difficult to achieve. A water softener is recommended to avoid damage and achieve good results.
