Hi ya allen,
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
counter top 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.
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.Your User manual
