Abstract: A water inlet device for an appliance having a cabinet containing a washing chamber characterized by a connector housing having a cavity receiving a diaphragm valve coacting with a valve seat on a port to control flow through the cavity with the operation of the diaphragm valve being controlled by a pilot valve disposed in the appliance. The water inlet device is particularly adapted for portable appliances and preferably has means for forming a quick connection to a source of water. The diaphragm is provided with at least one orifice to allow the source of water to bleed into a pressure chamber to bias or urge the diaphragm valve to a closed position and the pilot valve selectively bleeds this pressure chamber to cause a pressure differential on the diaphragm to selectively open the valve to admit water to the washing chamber of the appliance.
