A control system for a washing machine having an aspirator connected to the discharge side of the inlet valve. The aspirator vacuum port provides a vacuum signal through a one-way valve to a vacuum reservoir which supplies a vacuum signal via a control valve to one or more vacuum responsive diaphragm actuators. The force output of the actuators is employed for auxiliary machine functions such as direct mechanical actuation of the drain valve or operating the recirculation pump motor start switch.
