of drying

Aluminum items
touching dishes

PROBLEM

Spotting

Silica film or
etching
(silica film is a

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 “Cycle and option
tips” 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 hand-washing. To slow this pro-
cess, use a minimum amount of detergent
but not less than one tablespoon per load.
Use a liquid rinse agent and underload the
dishwasher to allow thorough rinsing. Silica
film and etching are permanent 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.
