An automatic washer having an improved sump formed in a bottom wall of the wash tube. The sump acts a collection zone for wash liquid and is spaced a sufficient distance from the wash basket and has sufficient capacity such that it can collect sufficient amount of wash liquid therein to present a constant supply of wash liquid to the pump while preventing the collected wash liquid from coming in contact with the basket while in the collection zone. The sump has a rear wall which forms a chord of the tube and a front wall which is flush with the circumferential wall of the tube. The sump also has a sloping bottom wall which communicates at a lowest portion thereof with the suction inlet of the pump, which the sump overlies.
