Rinse Aid Dispenser; Dishwasher Efficiency Tips - Whirlpool DU915 Series Use & Care Manual

How much detergent to use
The amount of detergent to use depends on the hardness of
your water and the type of detergent. If you use too little,
dishes won't be clean. If you use too much in soft water,
glassware will etch.
Water hardness can change over a period of time. Find out
your water's hardness by asking your local water department,
water softener company, or county extension agent.

section of the detergent dispenser with the cover closed. Follow
instructions on the package when using liquid dishwasher
detergent, concentrated powdered detergent or tablet detergent.
IMPORTANT: See "Cycle Selection Charts" for which detergent
dispenser sections to use with each cycle.
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 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 3 months. You do not
have to wait until the dispenser is empty to refill it. Try to keep it
full, but be sure 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,

4. Clean up any spilled rinse aid with a damp cloth.
5. Replace the Fill Indicator cap. Close tightly.
Pre-Wash
Hot water dissolves and activates the dishwashing detergent.
6 tsp (30 mL)
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.
