A plastic dishwasher tub and support structure is disclosed. A single piece is formed into a rear frame that attaches to the door frame of the dishwasher. The rear frame is in an inverted U-shape with arms formed by bending a portion of the legs of the U out of the plane of the U. The bight of the U supports the rear of the tub while the arms attach to the door frame and serve as skids for the dishwasher. The plastic tub is formed with integral reinforcing ribs on the tub portion to bear against the rear frame. In addition, retention blocks are cantilevered from the tub bottom to extend below the reinforcing ribs. The bight of the rear frame sides into the space between the blocks and ribs during assembly and prevents up and down and fore and aft movement of the tub with respect to the frame. Strips are placed on the jambs of the door frame astride the counterbalance levers on the door. These strips limit the travel of the door in the open position. The door frame is formed from a U-shaped length of angle iron. The door frame engages ribs integrally formed on the top and sides of the tub, parallel to the open front.
