Some plumbing codes require use of a drain air gap be-

tween an undercounter dishwasher and the droin system of the house. The air gap is usually located above the sink or on the lop of the counter near the dishwasher to prevent the possibility of water bucking 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
