Abstract
A dishwasher includes a shiftable rack provided with a washing agent dispersal system including a housing into which washing fluid is delivered. When the rack is shifted to a retracted position within a tub of the dishwasher, a tube feed system is employed to selectively distribute washing fluid from a pump assembly to each of multiple spray arms, the housing of the washing agent dispersal system and an auxiliary spray unit carried by the upper rack.
