Problem with: Possible Cause/Cure:
Too much foam in the wash solution The detergent dosage should be decreased. Detergent in use must be
designated for an automatic dishwasher.

is not empty, consider increasing dosage. See section regarding
Rinse Aid dispenser. If present, check properly functioning
household water softener.
Tarnishing/ rusting of stainless steel Do not leave covered with salt or acid foodstuffs. Use Rinse & Hold
program, if wash program not started immediately after loading. Do
not wash in direct contact with silver-place in separate sections of
the cutlery basket. Do not leave in a damp dishwasher for long
periods - drying by hand is best. Check household water softener is
functioning correctly.
Tarnishing of silverware Do not leave covered with salt or acid foodstuffs. Use Rinse & Hold
program if wash program not started immediately after loading. Do not
allow undissolved detergent to come into contact with silver,otherwise
black spots occur. Keep silver separate from other metals. Wash
with a good detergent containing tarnish inhibitor. Check household
water softener is functioning correctly.
Tarnishing of aluminum Usually caused by hot water - tarnish is not injurious in any way, but
is unsightly. If your preference is to wash such items in the dish-
washer versus by hand, remove these items before the final hot rinse
has begun.
Colored aluminum Color can be removed by hot alkali. These items not recommended
for washing in an automatic dishwasher.
Crystal glass, Glasses & other glassware
Stack carefully to avoid rubbing and jabbing. Excessively softened
water can damage glass. Check household water softener is
functioning correctly. Susceptible to damage by hot water check
suitability for use in a dishwasher.
Glaze decorations Some items especially antiques, are not safe in a dishwasher. Wash a
sample piece of suspect ware for a few weeks to check suitability.
Short washing cycles and lower temperatures will help minimize
problems and keep decorations brighter.
Handles Some glued on handles will not be safe at high temperatures. Bone,
wood or plastic can be susceptible to hot water. Test one piece by
washing for a few weeks.
Pieces of cutlery produced from two types of metal are susceptible to
electrolytic corrosion. Knives produced with stainless steel blades
and silver handles can corrode if left in the dishwasher.
Plastics Thermosetting plastics can dull or crack in hot water.
Thermoplastics can melt. Special care may be needed. Most plastic
items will not dry well due to the nature of the material.
Some hand drying may be necessary.
