A dishwasher for treating dishes includes a tub at least partially defining a treating chamber, the tub having a bottom portion with a sump opening therein, a liquid spraying system supplying a spray of liquid to the treating chamber, and a liquid recirculation system recirculating the sprayed liquid from the treating chamber to the liquid spraying system to define a recirculation flow path. A sump is positioned in the sump opening of the bottom of the tub within the recirculation flow path, the sump having an outlet therein located adjacent the forward portion of the sump opening. A pump has an inlet fluidly interconnected with the outlet of the sump, the pump configured to receive fluid from the outlet of the sump and impel the fluid along the recirculation flow path toward the treating chamber.
