PROBLEM CAUSE SOLUTION
Spotting

(continued)
Use of incorrect
detergents
Incorrect amount
of detergent
Use of ineffective
detergents
Insufficient fill due to
low water pressure
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.

ensure water entering dishwasher is 120°F
(49°C) minimum. See the "To check water

quate enclosure for proper operation.

properly
Plastics
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.
Silica film or
etching
(silica film is a
white iridescent
deposit: etching
is a cloudy film)
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 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.
Black or gray

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.
