Solutions to Common Dishwashing Problems
Before calling for service, review this list. It
may save you both time and expense. This list
includes common experiences that are not the
result of defective workmanship or material in
your dishwasher.
Food Soils Left on Dishes
• Choose another cycle for longer washing time.
• Check rack loading section for proper loading—
avoid nesting items.
• Home water pressure may be too low—should
be 20 to 120 pounds per square inch (psi).
• Check incoming water temperature. It should be
at least 120°F (49°C). (See Factors Affecting
Performance.)
• Check water hardness. For extremely hard
water, it may be necessary to install a water
softener. (See Detergent Chart.)
• Use fresh detergent.
• Check to make sure tower in lower rack is not
blocked.
• Make sure items are not blocking the spray arm,
preventing it from rotating.
Dishes not Dry
• Select Hot Dry option.
• Make sure the rinse aid dispenser is filled.
• Increase the amount of rinse aid. (See Rinse
Aid.)
• Check the incoming water temperature. Be sure
it is at least 120°F (49°C).
• Check for proper loading—avoid nesting items.
• Plastic items may need to be towel dried.
• Cups with a concave bottom will collect water.
Dishware Chipped
• Load with care and do not overload. (See
Preparing and Loading dishes.)
• Place delicate items in top rack.
• Place glasses securely against pins and not
over pins.
• Load items so they are secure and don't jar
loose when moving racks in and out. Move
racks in and out slowly.
• Make sure tall glasses and stemware will clear
top of tub when rack is pushed in.
• Fine antique china and crystal should be hand-
washed.
Glassware/Flatware Spotted or
Cloudy
• Check water hardness. For extremely hard
water, it may be necessary to install a water
softener. (See Detergent Chart.)
• Water temperature may be low. Avoid extremely
low or high temperatures. (See Factors
Affecting Performance.)
• Avoid overloading and improper loading. (See
Preparing and Loading Dishes.)
• Use fresh detergent. Old detergent is
ineffective.
• Check to see that proper amount of detergent is
being used. Also, check phosphate level. (See
Detergent Dispenser.)
• Home water pressure may be too low—it
should be 20 to 120 pounds per square inch
(psi).
Dishware Stained or Discolored
• Tea and coffee can stain cups. Remove the
stains by hand washing in a solution of
(120 ml) bleach and one quart (1 L) of warm
water. Rinse thoroughly.
• Iron deposits in water can cause a yellow or
brown film. A special filter installed in the water
supply line will correct this problem. (See
Removing Spots and Film.)
• Aluminum utensils can leave gray/black marks
when they rub against other items. Load
properly.
• Certain high acid foods can cause discoloration
of stainless steel and plastics if allowed to sit for
a long period. Rinse by hand if not operating
dishwasher at once.
• Mixing stainless steel and silver utensils in
silverware basket can cause pitting of the
stainless steel blades. Avoid mixing stainless
steel and silver.
Etching
• Using too much detergent in soft or softened
water causes this film that cannot be removed.
• Adjust the amount of detergent based on the
water hardness. (Check Detergent Chart.)
• Lower the water temperature.
• Use the Cool Dry option.
