TROUBLESHOOTING

First try the solutions suggested here and possibly avoid the cost of a service call...

Dishwasher is not operating properly

■ Dishwasher does not run or stops during a cycle

Is the Start/Resume indicator flashing? Opening the door or

interrupting the power stopped the cycle. Close the door and

press START/RESUME.

Does the Start/Resume indicator flash 3 times when you

press START/RESUME? The dishwasher is waiting for you to

open the door after the last cycle. Open and close the door,

then press START/RESUME.

Is the door closed tightly and latched?

(NOTE: On models with a dual-digit display, the control

displays “- -” during a cycle if it believes the door is not

latched.)

Is the right cycle selected? Refer to the “Cycle Selection

Charts.”

Is there power to the dishwasher? Has a household fuse

blown, or has a circuit breaker tripped? Replace the fuse or

reset the circuit breaker. If the problem continues, call an

electrician.

Has the motor stopped due to an overload? The motor

automatically resets itself within a few minutes. If it does not

restart, call for service.

Is the water shutoff valve (if installed) turned on?

It is normal for certain cycles to repeatedly pause for several

seconds during the main wash.

■ Clean light is flashing

The dishwasher has malfunctioned. Call for service to check

heater circuit.

■ Dishwasher will not fill

Is the overfill protection float able to move up and down

freely? Press down to release.

■ Dishwasher seems to run too long

Is the water supplied to the dishwasher hot enough? The

dishwasher runs longer while heating water. Refer to the

“Dishwasher Efficiency Tips” section.

A delay automatically occurs in some wash and rinse cycles

until the water reaches the proper temperature.

■ Water remains in the dishwasher

Is the cycle complete?

■ Detergent remains in the covered section of the

dispenser

Is the cycle complete?

Is the detergent lump-free? Replace detergent if necessary.

■ White residue on the front of the access panel

Was too much detergent used? Refer to the “Detergent

Dispenser” section.

Is the brand of detergent making excess foam? Try a different

brand to reduce foaming and eliminate buildup.

■ Odor in the dishwasher

Are dishes washed only every 2 or 3 days? Run a rinse cycle

once or twice a day until you have a full load.

Does the dishwasher have a new plastic smell? Run a vinegar

rinse as described in “Spotting and filming on dishes” later in

this Troubleshooting guide.

■ Condensation on the kitchen counter (built-in models)

Is the dishwasher aligned with the countertop? Moisture from

the vent in the dishwasher console can form on the counter.

Refer to the Installation Instructions for more information.

Dishes are not completely clean

■ Food soil left on the dishes

Is the dishwasher loaded correctly? Refer to the “Dishwasher

Loading” section.

Is the water temperature too low? For best dishwashing

results, water should be 120°F (49°C) as it enters the

dishwasher. Refer to the “Dishwasher Efficiency

Tips” section.

Did you use the correct amount of fresh detergent? Use

recommended dishwasher detergents only. Refer to the

“Detergent Dispenser” section. Detergent must be fresh to be

effective. Store detergent in a cool, dry area. Heavy soil and/

or hard water generally require extra detergent.

Do you have hard water? You may need to increase the

amount of detergent you are using. Refer to the “Detergent

Dispenser” section. Also, you may need to switch to a

detergent with a phosphorus content of 8.7%.

Is detergent caked in dispenser? Use fresh detergent only. Do

not allow detergent to sit for several hours in a wet dispenser.

Clean dispenser when caked detergent is present.

Is the pump or spray arm clogged by labels from bottles and

cans?

Is the home water pressure high enough for proper

dishwasher filling? Home water pressure should be 20 to

120 psi (138 to 828 kPa) for proper dishwasher fill. If you have

questions about your water pressure, call a licensed, qualified

plumber.

Are high suds slowing the wash arm? Do not use soap or

laundry detergents. Use recommended dishwasher

detergents only.
