Detergent cakes in dispenser
Pump or spray arm
clogged by labels from bot-
tles and cans
Insufficient fill caused by
low water pressure
Slowdown of wash arm due
to high suds
Use fresh detergent only. Do not allow detergent to sit
for several hours in a wet dispenser. Check dispenser
for caked detergent. Clean dispenser when caked
detergent is present.
Remove labels before washing bottles and cans or wash
by hand. Refer to the "Tips for washing special items"
section, page 17.
Home water pressure should be 20 to 120 psi
(138-828 kPa) for proper dishwasher fill. A booster
pump on the water supply may be necessary if pressure
is too low.
Never use soap or laundry detergents. Use recommended
dishwasher detergents only.
Spots or stains on dishes
Spotting and filming Hard water or high mineral
content in water
Water temperature is too low
Conditioning the final rinse water with a liquid rinse agent
helps eliminate spotting and filming. Keep the dispenser
full with a rinse agent at all times.
Use the Water Heat option. If needed, turn home
water heater up to ensure water entering dishwasher is
120°F (49°C) minimum. Refer to the "Water temperature
tips" section page 11.
Use of incorrect detergents
Incorrect amount of
detergent
Use of ineffective detergents
Insufficient fill caused by low
water pressure
Use recommended dishwasher detergents only.
Refer to the "Using the detergent dispenser" section,
page 10. 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
(138-828 kPa) for proper dishwasher fill. A booster pump
on the water supply may be necessary if pressure is too
low.
NOTE: To remove spots and film from dishes, try a
vinegar rinse.

2. Remove all metal items.
3. Put 2 cups (500 mL) white vinegar in a container on
the bottom rack.
4. Run dishwasher through complete washing cycle.
Vinegar will mix with wash water.

ware. Usually caused by
some combination of soft
or softened water, alkaline
washing solutions, insufficient
rinsing, overloading
the dishwasher, and heat
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 1 tablespoon per
load. Use a liquid rinse agent and underioad the
dishwasher to allow thorough rinsing. Silica film and
etching are permanent and cannot be removed. Use the
No Heat Dry option.
