ABSTRACT OF THE DISCLOSURE A clothes washing machine which recirculates wash or rinse water from a surrounding tub into a clothes holding basket to reduce the quantity of water required for wash and rinse cycles. The fill level is controlled by an adjustable pressure-sensitive switch which senses the pressure level at the drain outlet located in the bottom of the tub in order to control water fill levels at the beginning of each wash and rinse cycle. The pressure-sensitive switch is reset prepara- tory to the initiation of each wash or rinse cycle of the tub by the low pressure existing in the tub bottom after the tub has been drained at the end of each wash and rinse cycle. In order to prevent false resetting of the pressure-sensitive switch by recirculation flow from the tub, the recirculation pump inlet intake is elevated above the drain outlet by a stand pipe which maintains a sufficient level of water in the tub above the reset pressure level to preclude resetting of the pressure-sensitive switch until the tub is drained through the drain outlet. The stand pipe is designed to provide an anti-vortex action to minimize the air intake into the recir- culation pump.
