Customer Questions and Answers for Washer Water Inlet Valve by Whirlpool

David, You need to use the appropriate water valve based on the serial number. The valves may look and act the same, but there is usually a change in the internal components. If your washer serial number starts with 12 thru 18 then use the W10821146. If the serial number starts with 19 or higher, you'll need to use the WP22004333. The 22004333 is a 60/40 fill valve. That means that when the washer is filling 60% of the water is cold and 40% of the water is hot. This is how manufacturers meet the energy efficient standards set by the government.
