PROBLEM CAUSE SOLUTION
Spotting
and filming
(continued)
Dishes do not
dry completely
Incorrect amount
of detergent
Use of ineffective
detergents
Insufficient fill due to
low water pressure
Follow recommendations on page 10 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.

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.
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 c aused 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 1 tablespoon per load.

dishwasher to allow thorough rinsing. Silica
film and etching are permanent and cannot
be removed. Use the AIR DRY option.
