SUGGESTED REMEDY
Be sure aluminum utensils, especially light weight foil-type
pans, do not touch dishes.
To remove spots, use a non-abrasive cleaner.
Be sure a utensil or handle has not prevented their turning.
Use only fresh detergent, store in a tightly closed container in
a cool dry place. Fill dispenser only when ready to start the
dishwasher. Use the recommended amount of detergent,
especially with hard water.
Check that the water valve is fully open. Make sure that the
water pressure is between 18 and 176 psi.
Load dishes to prevent water and detergent from being
trapped in or between items. Water should circulate freely.
Temporary solution: Pour 1 teaspoon to 1 tablespoon of citric
acid crystals in instead of the prewash detergent directly on
the inside of the door. Follow this prewash with a full
detergent wash. Use the pots/pans or normal wash cycle.
Permanent solution: Install an iron removal system in the water
supply.
Yellow film on sterling silver results when washing copper
items in the same load. Silver polish usually removes the stain.
Tea or coffee can stain cups. Remove stains by hand, using a
solution of 1/2 cup bleach and 3 cups warm water. (Do not
use on sterling silver or silverplate.)
Rinse flatware that is to stand several hours before washing.
Do not put stainless steel and silver flatware in the same
silverware basket compartment. Direct contact between these
metals can cause permanent damage to silver.
Clean stained items with silver polish.
Do not use abrasives on stainless steel or silver.
Plastics vary in their ability to tolerate heat. Check washing
instructions for all plastic items to be sure they are dishwasher
safe. If they are, place in upper rack away from the heating
element.
Porous material Use a special cleaner for plastic.
DO NOT use bleach or scouring powder on these materials.
Compartment cover blocked
Old detergent
The cover may not be opening because of improperly loaded
items. Move dishes that may be blocking it.
If detergent is hard or caked in the box, throw away. Use only
fresh detergent. Add detergent just before starting the
dishwasher.
