Dishwasher Efficiency Tips

Hot water dissolves and activates the dishwashing detergent. Hot water also dissolves grease on dishes and helps glasses dry spot-free. For best dishwashing results, water should be 120°F (49°C) as it enters the dishwasher. 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. If your water heater is located far from the dishwasher, it may be necessary to run the hot water at the faucet closest to the dishwasher to minimize the amount of cold water in the water line.

To check water temperature

1.Run hot water at the faucet closest to your dishwasher for at least 1 minute.

2.Place a candy or meat thermometer in a glass measuring cup.

3.Check the temperature on the thermometer as the water is running into the cup.

■To save water, energy and time, do not rinse dishes before putting them into the dishwasher.

■Use a low energy, quick, or short cycle whenever possible. These cycles use less hot water and energy than a normal cycle.

■Use a delay feature (on some models) to run your dishwasher during off-peak hours. Local utilities recommend avoiding heavy usage of energy at certain times of day.

■During the summer, run your dishwasher at night. This reduces daytime heat buildup in the kitchen.

■Use the energy-saving dry option whenever possible. Allow longer drying times (overnight) when using these options. Use a rinse aid to improve drying.

■Use cycles or options that add extra heat to the wash or rinse portion of the cycle only when needed.

■Run your dishwasher with full loads. Run a rinse cycle after meals until the dishwasher is full.

■If your home is equipped with a water softener, you may want to avoid starting the dishwasher during the regeneration of the softener, as this may contribute to poor wash performance.

Cycle Selection Charts

Select the wash cycle and options desired. The dishwasher starts filling once you press a cycle, unless you select a delay wash. You can select an option as the machine is filling.

Your electronic dishwasher senses the soil level on your dishes. Soil level determines the length of some cycles, the amount of heat added to a wash or rinse, and the number of washes and rinses in a cycle.

Cycle time depends upon the soil on the dishes, and water usage may be higher for large amounts of soil. If dishes are lightly soiled, cycle time will be as shown.

After a wash cycle, the dishwasher remembers the options used and uses the same options in the next wash cycle unless new options are selected or Cancel/Drain is selected.

A “●” shows what steps are in each cycle. Your model may have some or all of the cycles shown.

Temperatures indicate where extra heat is added.

Water usage is shown in U.S. gallons/liters.

Cycle time includes dry time. An asterisk ( * ) by the cycle time indicates the cycle time might be longer depending on the temperature of the water entering the dishwasher. The cooler the water, the longer the cycle time. If the water is already hot enough, the cycle time will be as shown.
