A complete dishwasher and sink assembly, including equipment usually installed separately, forms a unit that can be inserted in a cut-out in a countertop, and supported and secured in position at a peripheral flange. The connections to the associated utilities are positioned for maximum convenience to standard locations. A sink is pivotally mounted to provide a cover for the dishwasher chamber, and stiffener-deflector arrangements are provided to assure that the interior spray does not produce leakage out to the countertop through ventilation passages at the peripheral flange. Spray is applied to racks of dishes, preferably from rotating spray heads mounted on a movable carrier, with the supply of water to the spray heads being conducted via the hollow interior of the carrier and also the hollow interior of a sequence of interconnected links. The rotatable spray heads are also hollow, with molded projections forming directional jet orifices. The reciprocating carrier is supported on a rotatable double-helix screw shaft, with a portion of the carriage in sliding engagement with the wall of the spray chamber so that the carriage is suspended from the shaft. An auxiliary interior faucet is provided for rinsing dishes, with the spigot position determining the off-on condition of an associated valve.
