ABSTRACT:
A dishwasher tub includes a bottom wall having a sump basin formed therein for containing a reservoir of washing fluid. The sump basin has an upper rim having a rear portion spaced inwardly from the rear edge of the bottom wall, opposite side portions spaced inwardly from the opposite side edges of the bottom wall, and a front portion spaced inwardly from the front edge of the bottom wall. The rim of the sump forms two spaced apart leg portions of the basin which extend forwardly into close proximity to the front spaced apart corners of the front wall of the tub. In addition to the sump basin, the bottom wall includes front, rear, and opposite side margins sloping upwardly from the rim of the sump basin to the rear, side, and front walls of the dishwasher tub. The resulting sump basin has a horseshoe-shaped configuration.
