To clean the drain air gap
Clean the drain air gap periodically to ensure proper drainage of
your dishwasher. Follow the cleaning instructions provided by the
manufacturer. With most types, you lift off the chrome cover.
Unscrew the plastic cap. Then check for any soil buildup. Clean if
necessary.
Storing Your Dishwasher
Storing for the summer
Protect your dishwasher during the summer months by turning
off the water supply and power supply to the dishwasher.
Winterizing your dishwasher
Protect your dishwasher and home against water damage due to
freezing water lines. If your dishwasher is left in a seasonal
dwelling or could be exposed to near freezing temperatures, have
your dishwasher winterized by authorized service personnel.

White residue on the front of the access panel
Was too much detergent used? Refer to the “Detergent
Dispenser” section.
Is the brand of detergent making excess foam? Try a different
brand to reduce foaming and eliminate buildup.
■ ■ ■ ■
Odor in the dishwasher
Are dishes washed only every 2 or 3 days? Run a rinse cycle
once or twice a day until you have a full load.
Does the dishwasher have a new plastic smell? Run a vinegar
rinse as described in “Spotting and filming on dishes” later in
this Troubleshooting guide.
■ ■ ■ ■
Condensation on the kitchen counter (built-in models)
Is the dishwasher aligned with the counter top? Moisture
from the vent in the dishwasher console can form on the
counter. Refer to the Installation Instructions for more
information.
Dishes are not completely clean
■ ■ ■ ■
Food soil left on the dishes
Is the dishwasher loaded correctly? Refer to the “Dishwasher
Loading” section.
Is the water temperature too low? If needed, turn home water
heater up to ensure water entering dishwasher is at least
120°F (49°C). Refer to the “Dishwasher Efficiency Tips”
section.
Did you use the correct amount of fresh detergent? Use
recommended dishwasher detergents only. Refer to the
“Detergent Dispenser” section. Never use less than 1 tb (15 g)
per load. Detergent must be fresh to be effective. Store
detergent in a cool, dry area. Heavy soil and/or hard water
generally require extra detergent.
Is detergent caked in dispenser? Use fresh detergent only. Do
not allow detergent to sit for several hours in a wet dispenser.
Clean dispenser when caked detergent is present.
Is the pump or spray arm clogged by labels from bottles and
cans? If you wash bottles and cans in your dishwasher, check
for labels clogging the pump or spray arm.
Is the home water pressure high enough for proper
dishwasher filling? Home water pressure should be 20 to 120
psi (138 to 828 kPa) for proper dishwasher fill. A booster
pump on the water supply can be added if pressure is too
low.
Are high suds slowing the wash arm? Never use soap or
laundry detergents. Use recommended dishwasher
detergents only.

Dishwasher door will not close
Is the bottom rack in backwards? The rack bumpers must
face the dishwasher door.
Spots and stains on dishes
■ ■ ■ ■
Spotting and filming on dishes
Is your water hard or is there a high mineral content in your
water? Conditioning the final rinse water with a liquid rinse
aid helps eliminate spotting and filming. Keep the rinse aid
dispenser filled.
Is the water temperature too low? If needed, turn home
water heater up to ensure water entering dishwasher is at
least 120°F (49°C). Refer to the “Dishwasher Efficiency
Tips” section.
Did you use the correct amount of effective detergent? Use
recommended dishwasher detergents only. Refer to the
“Detergent Dispenser” section. Never use less than 1 tb (15 g)
per load. Detergent must be fresh to be effective. Store
detergent in a cool, dry area. Heavy soil and/or hard water
generally require extra detergent.
Is the home water pressure high enough for proper
dishwasher filling? Home water pressure should be 20 to 120
psi (138 to 828 kPa) for proper dishwasher fill. A booster
pump on the water supply can be added if pressure is too
low.
