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 funnel in top rack is not

blocked.

• Make sure items are not blocking the spray

arms, preventing them from rotating.

• Check to see if the rinse aid dispenser

needs refilling.

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.

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.

• Make sure rinse aid dispenser is filled.

• Check to see that proper amount of

detergent is being used for cycle selected.

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 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.

Dishware Stained or Discolored

• Tea and coffee can stain cups. Remove the

stains by hand washing in a solution of 1/2

cup (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. Use the

Rinse/Hold cycle or 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.
