Solution
Use the Hi-Temp Wash option and do
not use the Lo-Energy Rinse option. If
needed, turn home water heater up to
ensure water entering dishwasher is
120°F (49®C) minimum. See recom­
mended procedure on page 15.
Use recommended dishwasher deter­
gents only.
Follow recommendations on pages 12
and 13 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 neces­
sary if pressure is too low.
If needed, turn home water heater up to
ensure water entering dishwasher is
120°F (49°C) minimum. See recom­
mended procedure on page 15.
Dishes must have proper water drainage.
Do not overload. Follow instructions for
loading dishwasher on pages 17-20. 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
process, use a minimum amount of
detergent but not less than one table­
spoon per load. Use a liquid rinse agent
and underload the dishwasher to allow
thorough rinsing. Silica film and etching
are permanent and can not be removed.
Use the Air Dry option.
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.
