Plastics
Water chemical reaction with certain types of glassware - usually caused by some combination of soft or softened water, alkaline washing solutions, insufficient rinsing, overloading the dishwasher, and heat of drying
Aluminum items touching dishes
SOLUTION
Use recommended dishwasher detergents only.
Follow recommendations in the “Using the Dispensers” section for amount. Heavy soil and/or hard water generally require extra detergent.
Use fresh detergent. Store detergent tightly- closed in a cool, dry place. Discard lumpy detergent.
Home water pressure should be 20 to 120 psi (138 to 828 kPa) for proper dishwasher fill. A booster pump on the water supply may be necessary if pressure is too low.
If needed, turn home water heater up to ensure water entering dishwasher is 120°F (49°C) minimum. See the “Tocheck water temperature” section.
Undercounter dishwashers require ade- quate enclosure for proper operation. See Installation Instructions for complete information.
Dishes must have proper water drainage. Do not overload. See the “Loading Your Dishwasher” section. Use a liquid rinse agent to speed draining.
Some plastics, due to material, may need to be towel dried.
It may not be possible to prevent problem, except by
Load aluminum items so that they will not rub against dishes during washing. Do not wash throwaway aluminum items in the dishwasher because they may break down and cause marking. Remove aluminum markings by using a mild abrasive cleanser.
