Dishes do not dry completely
Dishes do not dry completely
■
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.
Dishes are not dry
■
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.
Excess moisture on racks and dishwasher interior
■
Check the rinse aid indicator to see that there is rinse aid in
the dispenser.
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. 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.
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 see the "Dishwasher
Maintenance Procedure" in the "Dishwasher Care" section.
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
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.
Dishes are not completely clean
Food soil left on the dishes
■
Is the dishwasher loaded correctly?
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 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.
