POSSIBLE CAUSE
Detergent is too old. Detergent must be fresh and
Home water
pressure is too low
to fill dishwasher
properly.
Using too much
detergent
The inlet water
temperature
exceeds 150°F
(65°"C).
Aluminum items
rubbing dishes
during washing.
Disposable
aluminum items
can break down in
the dishwasher and
cause marking.
Large amounts of
tomato-based foods
on dishes placed in
the dishwasher.
POSSIBLE CAUSE
Dishes are not
loaded properly
to allow water
drainage.
Rinse Aid not used
or dispenser is
empty.
Used an air dry
or energy-saving
option.
SOLUTION
dry to be effective. Store
detergent in a cool, dry area.
Water pressure to the home
should be 20 to 80 psi
(138 to 552 kPa) for proper
dishwasher fill. A booster
pump on the water supply
can be added if pressure is
too low.
If you have soft water use
less detergent, but do not
use less than 1 Tbsp. (15 g)
per load.
Lower the incoming water
temperature.
Hand wash aluminum items.
Remove aluminum markings
by using a mild abrasive
cleaner.
Use a stain removal product
to remove stains from
your dishwasher. Stains
will not affect dishwasher
performance.
SOLUTION
Do not overload dishwasher.
Place glasses and cups in
the rack so that the bottom
surface is slanted to allow
water to run off.
Use a liquid rinse aid to
speed drying and keep the
dispenser full.
For dryer dishes, select a
Cycle that allows a Heated
Dry option.
