Cleaning

Cleaning the exterior
In most cases, regular use of a soft, damp cloth or sponge and a
mild detergent is all that is necessary to keep the outside of your
dishwasher looking nice and clean. If your dishwasher has a
stainless steel exterior, a stainless steel cleaner is recommended.
Cleaning the interior
Hard water minerals can cause a white film to build up on the
inside surfaces, especially just beneath the door area.
Do not clean the dishwasher interior until it has cooled. Wear
rubber gloves. Do not use any type of cleanser other than
dishwasher detergent because it may cause foaming or sudsing.
To clean interior
Make a paste with powdered dishwasher detergent on a damp
sponge and clean.
OR
Use liquid automatic dishwasher detergent and clean with a
damp sponge.
OR
See the vinegar rinse procedure in "Spotting and filming on
dishes" in "Troubleshooting."
NOTE: Run a normal cycle with detergent after cleaning the
interior.

Cleaning the Filter Screen

The filter system requires periodic cleaning as needed.
To clean screen
1. Wait at least 20 minutes after a cycle for the heating element
to cool down
2. Unload and slide the bottom rack forward. (Remove bottom
rack if necessary to reach filter screen.)
3. Remove collected particles from the screen with your fingers
or a paper towel.
4. Replace the bottom rack with the rack bumpers facing the
door.
NOTE: Do not clean the dishwasher interior until it has cooled.

DISHWASHER CARE

Check the drain air gap anytime your dishwasher isn't draining
well.
Some state or local plumbing codes require the addition of a
drain air gap between a built-in dishwasher and the home drain
system. If a drain is clogged, the drain air gap protects your
dishwasher from water backing up into it.
The drain air gap is usually located on top of the sink or
countertop near the dishwasher. To order a drain air gap, contact
your local dealer; or call us or your nearest designated service
center and ask for Part Number 300096. For more information,
see "Assistance or Service."
NOTE: The drain air gap is an external plumbing device that is
not part of your dishwasher. The warranty provided with your
dishwasher does not cover service costs directly associated with
the cleaning or repair of the external drain air gap.
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 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.
