A drawer-type dishwasher includes a pump system which functions to pump and filter washing fluid in the dishwasher. The pump system includes a sump having an inlet passage, a recirculation passage, a drain passage, a coarse article collection chamber, a filter assembly that is divided into a filter chamber and a washing fluid manifold, and a stationary hub that rotatably supports a wash arm for spraying washing fluid onto dishware supported in the dishwasher. The filter chamber includes a fine particle collection chamber having a valve that selectively opens to allow particles trapped in the filter chamber and fine particle collection chamber to flow to the drain passage. The filter assembly includes a cover having a plurality of radial spaced openings over the filter chamber, as well as a central opening that receives a stationary hub member which rotatably supports a wash arm.
