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.

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
