Clogged drain air Some plumbing codes require use of a drain air gap be-
gap
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 dish-
washer due to a plugged drain. The drain air gap is NOT a
part of the dishwasher and is NOT covered by the dish-
washer warranty. The drain air gap should be kept clean to
ensure proper draining of the dishwasher.
