Troubleshooting guide

Detergent must be fresh to be effective. Store detergent in a cool,
dry area. 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 dishes, try a white vinegar
rinse. This procedure is intended for occasional use only. Vinegar is
an acid, and using it too often could damage your dishwasher.
1. Wash and rinse dishes. Use an air-dry or an energy saving dry
option. Remove all silverware or metal items.
2. Put 2 cups (500 mL) white vinegar in a glass or dishwasher-safe
measuring cup on the bottom rack.
3. 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.
• 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 prevent the problem, except by hand washing.
To slow this process use a minimum amount of detergent but not
less than 1 tb (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 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 recommended.
• 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.
Dishes do not dry completely
• Dishes are not dry
Did you load your dishwasher to allow proper water drainage?
Do not overload. Refer to the “Loading” section in the Consumer
Reference Guide. Use a liquid rinse aid to speed drying.
Are the plastics wet? Plastics often need towel drying. Is the rinse aid
dispenser empty?
Refer to the “Rinse Aid Dispenser” section.
Did you use an air-dry or energy-saving dry option? Use a heated
drying option for dryer dishes.
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.
Noises
• Grinding, grating, crunching or buzzing sounds
A hard object has entered the wash module. When the object is
ground up, the sound should stop. If the noise persists after a
complete cycle, call for service.
