Whirlpool WDF760SADM Owner's Manual

■

Check to see if items loaded for ™ wash option have shifted. 
Reload to keep items from interfering with spray jets or spray 
arm. 

■

Did you use a rinse aid? Your dishwasher is designed to use 
rinse aid for good drying performance. Without rinse aid your 
dishes and dishwasher interior will have excessive moisture. 
The heat dry option will not perform as well without rinse aid.

■

Did you load your dishwasher to allow proper water drainage? 
Do not overload. Use a liquid rinse aid to speed drying.

Are the plastics wet? Plastics often need towel drying.

Is the rinse aid dispenser empty? 

Did you use an air-dry or energy-saving dry option? Use a 
heated drying option for dryer dishes.

■

Check the rinse aid indicator to see that there is rinse aid in the 
dispenser.

■

Is your water hard, or is there a high mineral content in your 
water? Conditioning the final rinse water with a liquid rinse aid 
helps eliminate spotting and filming. Keep the rinse aid 
dispenser filled. Always use a high-temp option. If your water 
hardness is 13 grains or above, it is strongly recommended that 
you install a home water softener. If you do not wish to drink 
softened water, have the softener installed onto your hot water 
supply.

Is the water temperature too low? For best dishwashing results, 
water should be 120°F (49°C) as it enters the dishwasher.

Did you use the correct amount of effective detergent? Use 
recommended dishwasher detergents only. Do not use less 
than 1 tbs (15 g) per load. Detergent must be fresh to be 
effective. Heavy soil and/or hard water generally require extra 
detergent.

Using dishwasher detergent tablets and packs have been 
proven better than powder, liquid or gel detergents to reduce 
filming on your dishes. By using these tablets and packs, over 
time this will start to reduce or eliminate white film. Also, by 
using a rinse aid you can minimize repeat buildup of white film.

Is the home water pressure high enough for proper dishwasher 
filling? Home water pressure should be 20 to 120 psi (138 to 
828 kPa) for proper dishwasher fill. If you have questions about 
your water pressure, call a licensed, qualified plumber. 

NOTE: To remove spots and film from glassware, remove all 
silverware and metal items and run a vinegar rinse as described 
in “Dishwasher Care.”

■

Sometimes there is a water/chemical reaction with certain 
types of glassware. This is usually caused by some 
combination of soft or softened water, alkaline washing 
solutions, insufficient rinsing, overloading the dishwasher, and 
the heat of drying. It might not be possible to avoid the 
problem, except by hand washing. 

To slow this process use a minimum amount of detergent but 
not less than 1 tbs (15 g) per load. Use a liquid rinse aid and 
underload the dishwasher to allow thorough rinsing. Silica film 
and etching are permanent and cannot be removed. Do not use 
heated drying.

■

Has the dishwasher detergent removed cookware seasoning? 
Reseason cookware after washing it in the dishwasher.

■

Does your water have high iron content? Rewash dishes using 
1-3 tsp (5-15 mL) of citric acid crystals added to the covered 
section of the detergent dispenser. Do not use detergent. 
Follow with a Normal wash cycle with detergent. If treatment is 
needed more often than every other month, the installation of 
an iron removal unit is suggested.

■

Are aluminum items rubbing dishes during washing? 
Disposable aluminum items can break down in the dishwasher 
and cause marking. Hand wash these items. Remove 
aluminum markings by using a mild abrasive cleaner.

■

Are large amounts of tomato-based foods on dishes placed in 
the dishwasher? It may be necessary to use a stain removal 
product to remove stains from your dishwasher. Stains will not 
affect dishwasher performance.

■

Surging sounds can occur periodically throughout the cycle 
while the dishwasher is draining

■

Normal water valve hissing may be heard periodically, during 
the water fill.

■

A normal snap sound may be heard when the detergent 
dispenser opens during the cycle, and when the door is 
opened at the end of the cycle.

■

A hard object has entered the wash module (on some models). 
When the object is ground up, the sound should stop. If the 
noise persists after a complete cycle, call for service.

■

 It is normal to hear numerous starts and stops during 
throughout your entire cycle. These Starts and stops are 
needed to provide optimal cleaning performance and energy 
savings.

■

Depending on the cycle selected and the soil level sensed by 
the “Optical Water Sensor” (In some models) you will 
experience more starts and stops throughout the entire cycle.
