Some plumbing codes require use of a drain air gap be-
tween an undercounter dishwasher and the drain system
of the house. The air gap is usually located above the sink
or on the top of the counter near the dishwasher to prevent
the possibility of water backing up from the drain into the
dishwasher due to a plugged drain. The drain air gap
IS
NOT a part of the dishwasher and is NOT covered by the
dishwasher warranty The drain air gap should be kept
clean to insure proper draining of the dishwasher
