Abstract
An under counter dish washing machine has an upper spray assembly with a spray base recessed at the top of the wash compartment. An enclosed control housing is provided around the recess to house various controls in order to make use of what is otherwise wasted space. The sump of the machine is covered by a screen having an opening in which a pump filter moves up and down to open and close the drain opening. The filter has a perforated body so that all water draining to the sump must pass through either the screen openings or the perforations of the pump filter. The supply hose which delivers water to the machine is relieved from constant water pressure by a solenoid valve which closes except during a fill cycle of the machine.
