SOLUTION PROBLEM
Brown stains
on dishes and
dishwasher inte-
rior
CAUSE
High iron content
in water supply
Remove by washing dishes (after food soil
has been removed) with 1 teaspoon to 1 table-
spoon of citric acid crystals added to covered
section of detergent dispenser. Do not use
detergent. Follow with a light wash cycle and
detergent. If treatment is needed more often
than every other month, we recommend
installation of an iron removal unit.

Chipping of

Large amounts of
tomato-based foods

the dishwasher
Dishes only washed
every 2-3 days
Improper loading
Stains will not affect dishwasher performance
and can gradually fade over time. Regular use
of Rinse Only reduces the chance of staining.
If air in the dishwasher is heated during the
"dry" portion of the cycle, stains may fade
slower than if the Air Dry option is selected.
Run a Rinse Only cycle at least once or twice
a day until a full load is accumulated.
Load dishes and glasses so they are stable
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.
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 dish-
washer. Do not load silverware or other
metals in the dishwasher.
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 Wash 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.
