Whirlpool Dishwasher Water Inlet Valve Parts — Models & Compatibility

Your Whirlpool dishwasher won't fill, or it's leaking water onto the floor. Nine times out of ten, it's the water inlet valve. This hub covers the W10158389 replacement valve that fits dozens of Whirlpool, KitchenAid, Kenmore, and Maytag dishwasher models from the DU, GU, and related series.

Is This the Right Part for Your Model?

Check your dishwasher's model number — it's usually on a sticker inside the door frame or along the inner door edge. Match it against the compatible models list below. The W10158389 valve replaces older part numbers WPW10158389, AP6015932, 8558986, 8563405, and PS11749213, so if you've got any of those listed in your manual, you're good to go.

About This Replacement Part

The water inlet valve controls water flow into your dishwasher's tub during the fill cycle. When it fails, you'll see symptoms like the dishwasher refusing to fill, water pooling underneath the unit, or poor cleaning performance because there's not enough water reaching the spray arms. Sometimes the valve gets noisy — a buzzing or humming sound that won't quit. This OEM replacement installs exactly like the original valve, and owners report it's a straightforward swap with fair pricing for what you get.

Common Failure Signs

• Won't fill with water: The most obvious symptom — cycle starts but no water enters
• Leaking: Water dripping from under the dishwasher, often from a cracked valve body
• Not cleaning dishes properly: Insufficient water pressure means weak spray action
• Noisy operation: Valve solenoid buzzing or humming during fill cycles
• Not draining: Sometimes a stuck valve creates backflow issues

What You're Getting

This is the genuine OEM valve assembly with mounting bracket and electrical connector. It's a direct fit replacement — no modifications, no adapter kits. The valve body handles standard household water pressure and includes the solenoid coil assembly. Users consistently mention the install being exactly like the original, which means you're dealing with the same mounting holes and hose connections your old valve used.

Installation Overview

You'll need to shut off water supply, disconnect power, and remove the lower access panel. The valve sits behind the lower kickplate, usually on the left side. Two hoses connect to it — inlet from your home's supply line and outlet to the tub. Disconnect the wire harness, remove the old valve's mounting screws, swap it out, and reconnect everything. Most people finish in under 30 minutes.

Price and Value

At $40.99, you're getting an OEM part that matches factory specs. Cheaper aftermarket valves exist, but they often leak within months or have solenoids that fail early. This valve uses the same materials and manufacturing as what came in your dishwasher originally, which is why owners call it a fair price for an easy repair that actually lasts.
