Abstract

A dishwasher includes a tub, lower and upper racks removably mounted within the tub, a first-level spray arm mounted in the tub above below the lower rack, a second-level spray arm mounted in the tub between the lower and upper racks and having an upwardly extending funnel, and a nozzle assembly mounted at the top of the tub above the upper rack. The nozzle assembly includes a downwardly directed spray nozzle axially aligned with the funnel, a third-level spray arm which encircles and rotates about the nozzle, and a retainer which is secured to the nozzle below the third-level spray arm and supports the third-level spray arm. The nozzle has a main body forming a central passage and a mounting flange integral with an upper end of the main body and forming transfer openings about the central passage. The nozzle extends through the third-level spray arm so that wash fluid is sprayed through the central opening to the funnel of the second-level spray arm and wash fluid is supplied through the transfer openings to an internal cavity of the third-level spray arm.
