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.

NOTE: To remove spots and film from dishes, try a white
vinegar rinse• This procedure is intended for occasional
use only. Vinegar is an acid and using it too often could
damage your dishwasher.
1. Wash and rinse dishes• Use an air-dry or an energy
saving dry option. Remove all silverware or metal
items•
2. Put 2 cups (473 mL) white vinegar in a glass or
dishwasher-safe measuring cup on the bottom rack•
3. Run the dishwasher through a complete washing
cycle using an air-dry or an energy saving dry option.
Do not use detergent. Vinegar will mix with the wash
water.
Silica film or etching (silica film is a milky, rainbow-
colored deposit; etching is a cloudy film)
Sometimes there is a water/chemical reaction with
certain types of glassware. This is usually caused by
some combination of soft or softened water, alkaline
washing solutions, insufficient rinsing, overloading the
dishwasher, and the heat of drying• It might not be
possible to prevent the problem, except by hand
washing.
To slow this process use a minimum amount of
detergent but not less than 1 tb (15 g) per load. Use a
liquid rinse aid and underload the dishwasher to allow
thorough rinsing. Silica film and etching are permanent
and cannot be removed. Do not use heated drying.
White spots on cookware with non-stick finish
Has the dishwasher detergent removed cookware
seasoning? Reseason cookware after washing in the
dishwasher.
Brown stains on dishes and dishwasher interior
Does your water have high iron content? Rewash dishes
using 1-3 tsp (5-15 mL) of citric acid crystals added to
the covered section of the detergent dispenser. Do not
use detergent. Follow with a Normal wash cycle with
detergent• If treatment is needed more often than every
other month, the installation of an iron removal unit is
recommended.
Black or gray marks on dishes
Are aluminum items rubbing dishes during washing?
Disposable aluminum items can break down in the
dishwasher and cause marking. Hand wash these items.
Remove aluminum markings by using a mild abrasive
cleaner.
Orange stains on plastic dishes or dishwasher
interior
Are large amounts of tomato-based foods on dishes
placed in the dishwasher? Stains gradually fade over
time. Regular use of heated drying will slew fading.
Stains will not affect dishwasher performance. Regular
use of a rinse cycle and an air-dry or energy-saving dry
option will reduce the likelihood of staining.
