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.”
Silica film or etching (silica film is a milky, rainbow-colored 
deposit; etching is a cloudy film)
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.
White spots on cookware with nonstick finish
Has the dishwasher detergent removed cookware seasoning? 
Reseason cookware after washing it in the dishwasher.
Brown stains on dishes and dishwasher interior
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.
Black or gray marks on dishes
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.
Orange stains on plastic dishes or dishwasher interior
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.
Noises
Surging sounds
Surging sounds can occur periodically throughout the cycle 
while the dishwasher is draining
Valve hissing
Normal water valve hissing may be heard periodically, during 
the water fill.
Snapping sound
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.
Grinding, grating, crunching or buzzing sounds
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.
Dishwasher stops and starts
Numerous starts and stops
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 cycle selected
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.
Dishes are not completely clean
Food soil left on the dishes
Is the dishwasher loaded correctly? 
Check and clean your filters regularly. See the table in 
“Filtration System” section for “Recommended Time Interval to 
Clean Your Filter.”
Did you choose the cycle that describes the most difficult soil in 
your dishwasher? If you have some items with heavier soils, 
use a heavier cycle.
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 fresh 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.
Is detergent caked in dispenser? Use fresh detergent only. Do 
not allow detergent to sit for several hours in a wet dispenser. 
Clean dispenser when caked detergent is present.
Is the pump or spray arm clogged by labels from bottles and 
cans? 
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.
Are high suds slowing the wash arm? Do not use soap or 
laundry detergents. Use recommended dishwasher detergents 
only.
Dishes in the P
OWER
S
COUR
™ wash area are not clean
Are the dishes loaded to face the P
OWER
S
COUR
™ spray jets? 
Load soiled dish surfaces to face the back of the dishwasher 
toward the P
OWER
S
COUR
™ spray jets. Tilt the dishes toward 
the back so water can drain from surfaces, and the lower spray 
arm can wash the item from below.
NOTE: Loaded items may shift when dish racks are pushed 
into the dishwasher. Make sure dishes do not interfere with the 
spray arms, water feed tube, or P
OWER
S
COUR
™ spray jets.
Are items loaded so they do not overlap? Load items only one 
row deep without any overlap so that the P
OWER
S
COUR
™ 
spray jets can reach all surfaces.
Dishes are damaged during a cycle
Chipping of dishes
Did you load the dishwasher properly? Load the dishes and 
glasses so they are stable and do not strike together from 
washing action. Minimize chipping by moving the rack in and 
out slowly. 
NOTE: Antiques, feather-edged crystal, and similar types of 
china and glassware might be too delicate for automatic 
dishwashing. Wash by hand.
