Dishes not clean—Check pages 4 to 8 for
information on correct wash cycle, proper loading,
water temperature, water pressure, hard water,
amount of detergent, old and ineffective detergent,
and dish placement. To maximize wash
performance clean the filter of all large food
particles after each wash. To ensure that you
clean the filter correctly refer to page 12.
Dishes not drying can be greatly improved by
using a rinse aid and hot water. Hot water raises
temperature of dishes to speed up drying. When
loading, invert cups and bowls so that water can
run off. Avoid nesting of articles. If dishes are not
completely dry at end of cycle (which may occur
when COOL DRY setting is used), open door, roll
out racks, and allow dishes to air dry.
Spotting—Spots form when hard water droplets
evaporate leaving a deposit. Low phosphate
detergents increase the problem in hard water. To
prevent, use hot water and a detergent with a
higher level of phosphates (preferably 8.7% or
higher), or use more of a low phosphate detergent.
Be sure to use a rinse aid. If water is very hard, it
may be necessary to install a water softener. Load
glasses and plates so they have minimum contact
with racks and pins. Avoid overloading. Spotting
will occur where dishes and glasses touch.
Cloudy films and streaking are usually
caused by a combination of hard water and an
insufficient amount of detergent. Low phosphate
detergents are also a factor. To correct, increase
amount of detergent, check water temperature and
always use a rinse aid. If water is very hard, it may
be necessary to install a water softener.
Etched film on glassware is caused by
using too much detergent in soft or softened water.
This film cannot be removed. It is more likely to
occur on soft leaded glass or expensive crystal. An
early warning of this condition is a cloudy
iridescent appearance on glasses. To prevent, be
sure dishwasher is getting a full fill of water. Water
should reach base of heating element. If water
level is low, have water pressure checked by a
plumber. Use less detergent and make sure water
temperature is not higher than 150°F (66°C).
Underload to assure thorough rinsing. Use the
COOL DRY Option.
Chipped dishes and glasses can result
from rough handling and improper loading. Do not
put glasses in direct contact with other items.
Place glasses securely against pins.
Crazing of older china and pottery
happens when items are subjected to very hot
water. Once crazing (fine cracks in the glaze)
appears, it cannot be removed. Do not machine
wash again or condition may worsen.
Coffee and tea stains can occur when water
contains traces of iron. To avoid stains, rinse cups
out immediately after use. Increase amount of
detergent and use a rinse aid. Water temperature
should be approximately 140°F (60°C). If problem
persists, install a water softener with an iron
removal unit. To remove stains, hand wash cups in
solution of 1/2 cup (120 ml) bleach and a quart (1 L)
of warm water. Rinse thoroughly.
Gray-black stains on dishes are caused by
manganese in water supply. To correct, install a
manganese filtering system into house water
supply.
Reddish-brown stains on dishes,
glasses and interior are caused by iron in
water. To avoid iron stain, increase detergent, use
water heated to approximately 140°F (60°C) and a
rinse aid. It may be necessary to install a water
softener with an iron removal unit. To improve
appearance, use a commercial rust and lime scale
remover.
Plastic items can lose their shape due to high
temperatures of automatic dishwashing. Read
labels before washing. Place washable items in top
rack away from heating element.
Discoloration of plasticware by some
foods, such as tomato sauce, can stain
plasticware. If stained, soak item in solution of 1
tablespoon dishwasher detergent and a quart of
hot water or in a solution of 1/2 cup (120 ml) bleach
and a quart (1 L) of hot water.
Fading of patterns and metallic trim is
due to many washings, detergent and hot water.
Most of today’s china is dishwasher safe. Antique,
handpainted china, and handpainted pottery
should be washed by hand.
