PROBLEM CAUSE SOLUTION
Spotting and
filming
(continued) Incorrect amount
of detergent
Follow recommendations on page 10 for
amount. Heavy soil and/or hard water
generally require extra detergent.
Use of ineffective
detergents Use fresh detergent. Store detergent tightly-
closed in a cool, dry place. Discard lumpy
detergent.
Insufficient fill due to
low water pressure
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.
Dishes do not
dry completely
Dishes do not drain
properly Dishes must have proper water drainage.
Do not overload. Follow instructions for
loading dishwasher on pages 7-9. Use a
liquid rinse agent to speed draining.
Plastics 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
process, use a minimum amount of deter­
gent 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 ENERGY
SAVER DRY option.
Black or gray
marks on dishes Aluminum items
touching dishes 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.
White spots on
cookware with
non-stick finish
Seasoning removed by
dishwasher detergents Reseason cookware after dishwasher
washing.
