Rinse Aid Dispenser; Dishwasher Efficiency Tips - Whirlpool DU920PWKT0 Use & Care Manual

Rinse aids prevent water from forming droplets that can dry as
spots or streaks. They also improve drying by allowing water to
drain off of the dishes during the final rinse by releasing a small
amount of the rinse aid into the rinse water. Your dishwasher is
designed to use a liquid rinse aid. Do not use a solid or bar-type.
Checking the dispenser
Check the center of the Fill Indicator cap. Clear means it needs
filling.
OR
Or you can remove the Fill Indicator cap. If an "E" is visible, the
dispenser is empty.
Filling the dispenser
The rinse aid dispenser holds 6 oz (175 mL) of rinse aid. Under
normal conditions, this will last for about three months. You do
not have to wait until the dispenser is empty to refill it. Try to keep
it full, but be careful not to overfill it.
1. Make sure the dishwasher door is completely open.
2. Remove the Fill Indicator cap.
3. Add rinse aid. Fill to the smallest opening in the lower part of
the dispenser. Overfilling can cause the rinse aid to leak out,
and could cause oversudsing.
4. Clean up any spilled rinse aid with a damp cloth.
5. Replace the Fill Indicator cap. Close tightly.
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.
Press the desired cycle. 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.
To use Rinse Only, press any cycle and turn the Cycle Control
knob to Rinse Only.
NOTE: Use the Air Dry option with the Rinse Only cycle.
A "O" 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. The Cycle
Control knob pauses as the water heats.
Water usage is shown in U.S. gallons/liters.
This model meets the ENERGY STAR ® guidelines for energy
efficiency.
Cycle time includes dry time. An asterisk ( * ) by the cycle time
indicates the cycle time might be longer depending on the
