The Whirlpool WP22004333 is a water inlet valve constructed solely for Whirlpool and Maytag washers. It is an essential piece of equipment that governs the flow of hot and cold water into the washer throughout different wash cycles. The valve governs water flow by means of solenoids, which are electromagnets. When a specific wash cycle is selected and the washing machine needs water, the control board transmits an electrical signal to the solenoid. This triggers the magnet, which unlocks the corresponding valve and enables water to enter the machine. Throughout the wash cycle, the control board toggles between the valves when necessary to fill the washer to the necessary water level for each and every wash stage.
