Replaced inlet valve assembly of Whirlpool Duet clothes washer. Disconnected supply hoses at machine. Easy access inside; removed three screws to remove top panel of cabinet. Unplugged three electrical connectors, retracted hose clamps at the soap/bleach dispenser, and removed one Torx screw to remove old valve assembly. Reversed procedure to install new assembly. About 1 hour total, working carefully to avoid damage -- less time than I expected. Washer functions normally; no leakage.
