Whirlpool Washer Water Inlet Valve Parts — Models & Compatibility

If your Whirlpool front-load washer keeps filling even when it's off, or you're seeing an F8 E1 error code, you're likely dealing with a failed water inlet valve. The W10599356 fits dozens of WFW-series models and typically fails due to mineral buildup or worn-out solenoids that can't properly shut off water flow. This hub covers which models use this specific valve and what you need to know before ordering.

Is This the Right Part for Your Model?

Check your washer's model number — it's typically on a sticker inside the door frame or along the top edge when you open the lid. If you've got a WFW70, WFW72, WFW75, WFW80, WFW81, or WFW85 series Whirlpool washer made between 2010-2018, this valve should fit. The part also works with select Maytag and Amana models that share the same valve design. Cross-reference your full model number (including the last digit or two) against the compatibility list below to confirm.

About This Replacement Part

The W10599356 water inlet valve controls when water enters your washer's tub during fill cycles. It contains dual solenoids that open and close based on electronic signals from the control board. When this valve fails, you'll notice water trickling into the tub even when the machine is completely off — sometimes enough to leak past the door seal and pool on the floor. Other times it'll overfill during cycles or throw an F8 E1 error, which specifically indicates a fill issue. One repair tech noted: "Discovered possible inlet valve malfunction... Sales representative was awesome!" after diagnosing continuous fill problems. The valve fails because minerals in hard water gradually clog the screens or the solenoid coils wear out and lose their magnetic seal. You'll need nut drivers, pliers, a socket set, and screwdrivers for the swap — most DIYers finish in 30-60 minutes, though removing old hose clamps can be stubborn if they've been on there for years.

Common Failure Symptoms

• Washer continues filling water even when turned off
• F8 E1 error code appears on display
• Water overfilling during wash cycles
• Water leaking past door seal back into tub when idle
• No water entering tub at all (less common, but happens when solenoids fail closed)

Installation Overview

You'll be working behind the washer, so pull it away from the wall and shut off both hot and cold water supply lines. Have a bucket ready — there's always residual water in the hoses and valve body. The valve mounts to the back panel with two screws and connects to four hoses: hot and cold supply lines coming in, and hot and cold dispenser lines going to the soap drawer. As one user put it: "As with all hoses that have been connected for a long time not easy to remove them from water inlet/soap tub." Expect some wrestling with spring clamps. Once the old valve is out, transfer the hoses to the new unit in the same configuration, secure everything, and test for leaks before pushing the washer back.

Replacement Part Numbers

The W10599356 supersedes and replaces these older part numbers: AP5692067, PS8689091, W10509710, and 3023192. If a repair guide or parts diagram lists any of those numbers, this is the current replacement.

What's in the Box

You're getting the complete inlet valve assembly with mounting bracket and wire harness connector. Hose clamps aren't included, so reuse your existing spring clamps or pick up new worm-drive clamps if the old ones are corroded. The valve comes pre-assembled — no need to install screens or solenoids separately.

Why This Part Fails

Water inlet valves don't last forever. The solenoid coils energize hundreds of times per month, and eventually the windings break down or the rubber diaphragms inside lose their flexibility. Hard water accelerates failure because calcium deposits clog the tiny mesh screens at each inlet port. When the screens get blocked, the valve struggles to let enough water through, putting extra strain on the solenoids. Sometimes the valve will stick open instead of closed, which is how you end up with water entering the tub when the machine is supposedly off. If you've been dealing with overfilling or that F8 E1 code, there's about a 90% chance the inlet valve is your problem.
