SOLUTION
See 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 for proper dishwasher fill. A booster pump on the water supply may be neces- sary 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 "To check water temperature" section.
Undercounter dishwashers require ad- equate enclosure for proper operation. See Installation Instructions for complete information.
Dishes must have proper water drainage. Do not overload. Follow instructions in the
"Troubleshooting" 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 hand washing. To slow this process, use a minimum amount of deter- gent but not less than 1 tablespoon per load. Use a liquid rinse agent and under- load the dishwasher to allow thorough
rinsing. Silica film and etching are perma- nent and cannot be removed. Use the Air
Dry option.
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.
Reseason cookware after dishwasher washing.
