Abstract
A safety valve is provided for an appliance having an electrically operated water inlet valve for receiving water used during operation of the appliance. A valve body is connected to the water supply upstream of the inlet valve, the valve body having a flow path for allowing water to flow through the valve body to the inlet valve. An electrically operated solenoid is connected to a valve gate, the valve gate being movably carried within the valve body and movable between a closed position and an open position that allows water to flow through the flow path. A portion of an electrical current from an appliance control system to the inlet valve for opening the inlet valve is conducted to the solenoid for moving the gate to the open position. The gate is spring biased to the closed position for returning the gate to the closed position when the current ceases to flow.
