Here is what the User Guide has to say...
Spots and stains on dishes
- Spotting and filming on dishes
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. 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.
- 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.
- 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

every other month, the installation of an iron removal unit is

items can break down in the dishwasher and cause marking. Hand wash
these items. Remove aluminum markings by using a mild abrasive
- 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
Dishes are not completely clean
- Food soil left on the dishes
Is the dishwasher loaded correctly? Can the spray arm rotate freely?
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. 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
still in the detergent cup? Use fresh detergent only. Do not block
the detergent dispenser. Is the water temperature too low? For best
dishwashing results, water should be 120°F (49°C) as it enters the
Dish Washer Care
Cleaning the Dishwasher
Clean the exterior of the dishwasher with a soft, damp cloth and
mild detergent. If your dishwasher has a stainless steel exterior, a
stainless steel cleaner is recommended.
NOTE: Do not clean the dishwasher interior until it has cooled.
Clean the interior of the dishwasher, with a paste of powdered
dishwasher detergent and water or use liquid dishwasher detergent
on a damp sponge to clean the cooled-down interior.
A white vinegar rinse may remove white spots and film. Vinegar is
an acid, and using it too often could damage your dishwasher.
Put 2 cups (500 mL) white vinegar in a glass or dishwasher-safe
measuring cup on the bottom rack. Run the dishwasher through a
complete washing cycle using an air-dry or an energy-saving dry
option. Do not use detergent. Vinegar will mix with the wash water
Periodically clean the coarse
filter cup located on the floor of
the dishwasher drawer. Remove
collected particles from the

dishwasher until the coarse filter
cup is securely in place and
