ABSTRACT OF THE DISCLOSURE A level control arrangement for dishwashers in which the in- flow to the dishwasher tub from the water supply line is automatically terminated when the water level in the tub reaches a predetermined level. The arrangement includes a two-stage level control valve dis- posed in a valve housing installed downstream of the water fill valve. The valve is moved into and out of engagement with the valve housing in response to a connector which in turn is in operative engagement with a stem of a float positioned in the dishwasher tub. When the water level in the tub approaches a predetermined washing level, the float rises in the tub to a position where the connector permits the valve to move to a sealing position, thereby terminating further flow to the dishwasher tub. When the water is drained from the tub, the float stem moves the connector thereby releasing the pressure exerted against the sealed valve through a port located within the valve. Further movement of the float stem and the connector opens the valve, thereby resetting the arrangement for the next fill sequence.
