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

Turn the cycle control knob to the desired cycle. If the door is latched, you will hear the cycles start and stop as the cycle control knob passes each cycle mark. This is normal and does not hurt the dishwasher. If you prefer, you can set the cycle control knob with the door unlatched.

NOTE: Use the Energy-Saver Dry option with the Rinse & Hold cycle (on some models).

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