Bottom rack does not fully slide into the dishwasher
■
Check to see if items loaded for TargetClean™ wash option
have shifted. Reload to keep items from interfering with spray
jets or spray arm.
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.
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 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
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 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" (on some models), you will
experience more starts and stops throughout the entire cycle.
