Problem, Cause, Solution Chart
A convenient checklist for handling minor performance problems. Go over this list before calling for
service. If you can't solve your dishwasher's problem, turn to page 23 for service information.
PROBLEM CAUSE
SOLUTION
Food Soil Left On
Dishes
Slowdown of wash arm
due to high suds
Use recommended dishwasher detergents only. Never use soap or
laundry detergents. Add more dishwasher detergent to increase
amount of suds-inhibitors.
Improper loading
Follow loading instructions in dishwasher Use and Care Guide.
Low water pressure
due to insufficient fill
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.
Use of incorrect, too
little or ineffective
detergent
Use recommended dishwasher detergents only. Follow recommen¬
dations in Use and Care Guide for amounts; never use less than one
tablespoon per load. Detergent must be fresh to be effective. Always
store it in a cool, dry area, preferably in an airtight container.
Detergent cakes in
dispenser
Use fresh detergent only. Do not allow detergent to sit for several
hours in a wet dispenser. Have dispenser checked to make sure it is
working properly.
Water temperature is
too low
Turn home water heater up so water entering dishwasher is 120°F
(49°C) minimum. See recommended procedure "Automatic Water
Heating," page 6. Do not select ENERGY SAVER-DRY.
Filter cleaning spray
nozzle on wash arm is
blocked
Remove lower wash arm and turn upside down. Check single
stainless steel spray nozzle and nine water jets located on underside
of wash arm. See page 16. Check to make sure openings are not
blocked.
Spotting and Filming Hard water or high
mineral content in
water
Conditioning the final rinse water with a liquid rinse agent helps
eliminate spotting and filming. See page 14.
Water temperature is
too low
Turn home water heater up so water entering dishwasher is 120°F
(49°C) minimum. See recommended procedure "Automatic Water
Heating," page 6. Do not select ENERGY SAVER-DRY.
Use of incorrect
detergents
Use recommended dishwasher detergents only.
Incorrect amount of
detergent
Follow recommendations in dishwasher Use and Care Guide for
amount. Heavy soil and/or hard water generally require extra
detergent.
Use of ineffective
detergents
Detergent should be fresh. Store in a cool, dry place, preferably in an
airtight container. Discard lumpy detergent.
Insufficient fill caused
by 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 necessary 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 in dishwasher Use and Care Guide. 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)
A water chemical
reaction with certain
types of glassware.
Usually caused by some
combination of soft or
softened water, alkaline
washing solutions, in¬
sufficient 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 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 ENERGY SAVER DRY.
