Before you call for service
TROUBLESHOOTING TIPS
Problem Possible Cause What To Do
Water standing in the
bottom of the tub
Air gap is clogged.
Clean the air gap. See the
CARE AND CLEANING
section.
High drain loop or air gap not
installed.
Refer to the Installation Instructions for proper drain line
installation.
Water won’t pump out of
the tub
Drain is clogged.
If you have an air gap, clean it. See the
CARE AND
CLEANING section.
If the dishwasher drains into a disposer, run disposer clear.
Check to see if your kitchen sink is draining well. If not,
you may need a plumber.
Steam This is normal. Warm, moist air comes through the vent during drying
and when water is being pumped out. This is necessary
for drying.
Sanitized or Cycle Sanitized
light does not illuminate at
the end of the cycle
The door was opened and the
cycle was interrupted during
final rinse.
Do not interrupt the cycle by opening the door during the
wash cycle.
The incoming water
temperature was too low.
Raise the water heater temperature to between 120°F
and 150°F (49°C and 66°C).
Noise Normal operating sounds:
Beeping at the end of the cycle
(on some models);
Detergent cup opening;
Water entering dishwasher;
Motor stops and starts at
various times during cycle;
Spray arms start and stop at
various times;
Drain pump sounds during
pump out;
Drain pump starts and stops
several times during
each drain.
These are all normal. No action is required.
Rattling dishes when the spray
arm rotates.
Make sure dishes are properly loaded. See the Loading
section.
Rattling silverware against door
during wash.
Tall utensils may be placed in the upper rack to avoid
bumping against inner door during wash cycle.
A white film on glassware,
dishware and the interior
This problem is likely caused
by a low quality phosphate-free
dishwasher detergent.
To remove the white film, run your dishes through a
dishwasher cycle with citric acid. Use a WG04A00103
citric acid kit found online. Otherwise, use Finish
®
Dishwasher Cleaner found at your local grocery store.
Pour the citric acid in the detergent cup and close the
cover. Place the filmed but otherwise clean glassware
and dishware in the dishwasher. Leave silverware
and other metal items out of the dishwasher. Turn
the dishwasher on and let it run through a complete
cycle without detergent. The glassware, dishware, and
dishwasher should come out film free. Alternatively,
a vinegar rinse may be used. Pour 1 cup (240 ml) of
vinegar into dishwasher just after the detergent cup
opens and let the dishwasher complete its cycle.This
may be repeated several times a year as needed. The
use of a rinse agent such as Finish
®
Jet-Dry
®
Rinse Aid
may help minimize a repeat build up of film. Also, the use
of a highly rated detergent such as Finish
®
Quantum
®
Automatic Dishwashing Detergent will help prevent
film build-up.
