Problem Cause Solution
Spotting and
Filming
(continued)
Water temperature is
too low
Use of incorrect
detergents
Incorrect amount of
detergent
Use of ineffective
detergents
Insufficient fill caused
by low water pressure
If needed, turn home water heater up to
ensure water entering dishwasher is
120°F (49“C) minimum. See recom­
mended procedure on page 13.
Use recommended dishwasher deter­
gents only.
Follow recommendations on page 10 for
amount. Heavy soil and/or hard water
generally require extra detergent.
Detergent should be fresh. Store in a
cool, dry place, preferably in an airtight
container. 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 necessary if pressure is too low.
Dishes Do Not Dry
Completely Dishes do not drain
properly
Plastics
Dishes must have proper water drain­
age. Do rK)t overload. Follow instruc­
tions for loading dishwasher on pages
15-17. 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 Irides­
cent Deposit;
Etching is a Cloudy
Film)
A water chemical
reaction with certain
types of glassware.
Usually caused by
some combination of
soft or softened water,
alkaline washing
solutions, insufficient
rinsing, over-loading
the dishwasher, and
heat of drying.
It may not be possible to prevent
problem, except by hand-washing. To
retard this process, use a minimum
aiTwunt of detergent but not less than
one tablespoon per load. Use a liquid
rinse agent and underload the dish­
washer to allow thorough rinsing. Silica
film arKf etching are permanent and can
not be removed. Use the Energy Saver
Dry option.
Black or Gray
Marks on Dishes Aluminum items Aluminum items should be loaded so
that they will not rub against dishes
during washing. Throw-away aluminum
items should not be washed in the
dishwasher because they may break
down and cause marking. Aluminum
markings can be removed by using a
mild abrasive cleanser.
