Abstract: 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 preparatory 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.
