Maytag Dishwasher Water Inlet Valve Parts — Models & Compatibility

If your Maytag dishwasher isn't filling with water—or fills too slowly—the water inlet valve is usually the culprit. This hub covers the W10327249 replacement valve that fits dozens of Maytag dishwasher models, including the MDB and WDT series. This valve controls water flow into your dishwasher tub, and when it fails, you'll know it: either no water, a trickle instead of a flow, or error codes that won't clear.

Is This the Right Part for Your Model?

Check your dishwasher's model number—it's typically on the door frame or along the inside edge when you open the door. Cross-reference it with the compatible models list below. The W10327249 valve replaces several older part numbers including WPW10327249, W10316814, and W11130743, so if you see those on your parts diagram, this valve is the right fit.

About This Replacement Valve

The W10327249 is a direct OEM-replacement water inlet valve that mounts at the bottom front of your dishwasher, connecting to your home's water supply line. It's an electric solenoid valve—when the control board signals it's time to fill, electricity opens the valve and water flows in. When that solenoid fails (usually from mineral buildup or electrical burnout), the valve stays closed and your dishes stay dirty. One installation note: you may need to remove the white plug connector in some applications to get your dishwasher's wiring harness to fit properly. It's not always necessary, but if the connector won't seat fully, pull that white plug and retry the connection.

What Causes Water Inlet Valves to Fail?

Hard water is enemy number one. Mineral deposits clog the valve's tiny screen filter and eventually lock up the solenoid mechanism. Electrical issues are the other common killer—voltage spikes or worn wiring can burn out the coil inside the valve. Either way, replacement is the only fix. These valves aren't serviceable, and trying to clean them rarely works for more than a few cycles.

Installation Overview

Turn off water and power before you start. Access is from the bottom front—you'll remove the lower kickplate panel, disconnect the water supply line (have a towel ready), unplug the wiring harness, and unbolt the old valve. The new valve installs in reverse order. Remember that white plug connector note: if your wiring won't mate up cleanly, remove it from the valve terminal and connect directly. The whole job takes about 20 minutes once you've got the panel off.
