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

Is the door closed tightly and latched?
Is the right cycle selected? Refer to the "Cycle Selection

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.

freely? Press down to release.

"Dishwasher Efficiency Tips" section.
A delay automatically occurs in some wash and rinse cycles
until the water reaches the proper temperature.

TROUBLESHOOTING

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. Do not use less than 1 tb
(15 g) per load. Detergent must be fresh to be effective. Store
detergent in a cool, dry area. Heavy soil and/or hard water
generally require extra detergent.
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?
