Remove by washing dishes (after food soil
has been removed) with 1 teaspoon to
1 tablespoon of citric acid crystals added to
covered section of detergent dispenser. Do
not use detergent. Follow with a Light cycle
and detergent. If treatment is needed more
often than every other month, we recom-
mend installation of an iron removal unit.

Stains will not affect dishwasher perfor-
mance and can gradually fade over time.
Regular use of Rinse-Wash Later reduces
the chance of staining. If air in the dish-
washer is heated during the "dry" portion of
the cycle, stains may fade slower than if the
Air Dry option is selected.
Odor in the Dishes only washed Run a Rinse-Wash Later cycle at least once
dishwasher every 2 to 3 days or twice a day until a full load is accumulated.
Chipping of Improper loading Load dishes and glasses so they are stable
dishes and do not strike together from washing
action. Moving racks in and out slowly will
also minimize chipping.
NOTE: Some types of china and glassware
are too delicate for automatic dishwashing
and should be hand washed; for example:
antiques, feather-edged crystal, and
similar items.
Removing
Keep the rinse agent dispenser filled with
a liquid rinse agent. A rinse
agent prevents water from
forming droplets and drying
as spots or streaks.
To remove spots and film on
dishes and glasses, or hard water film/lime
buildup on the interior of the dishwasher, you
may use white vinegar with the following
procedure:
1. Load clean dishes and glasses in
dishwasher. Do not load silverware
or other metals in the dishwasher.
spots and film
2. Put 2 cups of household vinegar (in a
glass or dishwasher safe measuring cup)
standing upright in the bottom rack.
3. Close and latch the door.
4. Select the Normal cycle and Air Dry
option. Do not use detergent. Allow the
dishwasher to complete the entire cycle.
NOTE: This cleaning procedure is intended
for occasional use only. Vinegar is an acid.
Excessive use may damage your
dishwasher.
