A continuous rinse and cool-down control for washers and washer-extractors is provided of a character which requires modification only of the electrical circuitry of existing commercial machines. The initial step in this control is to open the drain valve on an intermittent time basis, and in response water is added by a water level control to replace that which is drained. Preferably, the drain valve is opened every other time the direction of the drive is changed, and is closed after a preset interval determined by a timer. Since the machine is never completely drained by this method the rinsing operation is a continuous one.
