A wash arm construction for a dishwasher includes an elongated wash arm having a hollow spray cavity contained therein. Within the spray cavity are one or more subcompartments which have inlet openings providing communication from the spray cavity into the subcompartment. A first group of these spray openings is in direct communication with the spray cavity, and a second group of openings is in direct communication with the subcompartments. The size of the openings to the subcompartments from the spray cavity cause a lower spray pressure to be achieved within the subcompartments than is achieved in the spray cavity.
