Drain Air Gap
Check the drain air gap anytime your dishwasher isn't draining
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, call your
local dealer; or call us or your designated service center and ask
for Part Number 300096. For more information, see "Assistance
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.

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.
