Troubleshooting, Drain Air Gap | Whirlpool RUD5000, RUD3000, RUD5750

Drain Air Gap

Check the drain air gap anytime your dishwasher isn’t draining well.

Some state or local plumbing codes require the addition of a drain air gap between a built-in dishwasher and the home drain system. If a drain is clogged, the drain air gap protects your dishwasher from water backing up into it.

The drain air gap is usually located on top of the sink or countertop near the dishwasher. To order a drain air gap contact your local dealer, or in the U.S.A., call the Customer Interaction Center and ask for Part Number 300096.

NOTE: The drain air gap is an external plumbing device that is not part of your dishwasher. The warranty provided with your dishwasher does not cover service costs directly associated with the cleaning or repair of the external drain air gap.

To clean the drain air gap

Clean the drain air gap periodically to ensure proper drainage of your dishwasher. Follow the cleaning instructions provided by the manufacturer. With most types, you lift off the chrome cover.

Unscrew the plastic cap. Then check for any soil buildup. Clean if necessary.

Storing Your Dishwasher

Storing for the summer

Protect your dishwasher during the summer months by turning off the water supply and power supply to the dishwasher.

Winterizing your dishwasher

Protect your dishwasher and home against water damage due to freezing water lines. If your dishwasher is left in a seasonal dwelling or could be exposed to near freezing temperatures, have your dishwasher winterized by authorized service personnel.

Is the right cycle selected? Refer to the “Cycle Selection Chart.”

Is there power to the dishwasher? Has a household fuse blown or circuit breaker tripped?

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.

■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 counter top? Moisture from the vent in the dishwasher console can form on the counter. Refer to the Installation Instructions for more information.

■Food soil left on the dishes
