Abstract

A rotating spray arm is supported by a removable and vertically adjustable upper rack of a dishwasher. The fluid coupling for the spray arm is not affected by changes in the upper rack vertical position. The spray arm is also protected by a guard which forms a stand for the rack when removed from the dishwasher.
