Whirlpool Dishwasher Sump Filter Screen Parts — Models & Compatibility

If your Whirlpool dishwasher isn't draining completely or you're finding debris on clean dishes, there's a good chance the sump filter screen needs replacing. This small but critical component sits at the bottom of your dishwasher's sump assembly, catching food particles before they reach the drain pump. The WPW10463906 sump filter screen fits hundreds of Whirlpool, KitchenAid, Maytag, Jenn-Air, Amana, and Kenmore dishwasher models — making it one of the most commonly needed maintenance parts across multiple appliance brands.

Is This the Right Part for Your Model?

Check your dishwasher's model number before ordering. You'll find it inside the door frame, usually along the top edge or side when you open the door. Match your complete model number (including any letters and numbers after the dash) against the compatibility list below. This part replaces older part numbers W10463906, W10195360, and AP6021820, so if you've ordered any of those in the past, this is the updated replacement.

About This Replacement Part

The sump filter screen is a fine-mesh component that prevents food debris, broken glass, and other foreign objects from entering your dishwasher's drain pump. Over time, this screen can become clogged with mineral deposits from hard water, develop tears from sharp objects, or crack from age and repeated heating cycles. When the screen fails, you'll notice poor drainage, standing water at the bottom of the tub after cycles, or unusual grinding noises during the drain phase. Replacing this $24.99 part is considerably cheaper than replacing a damaged drain pump — which can fail prematurely when debris bypasses a compromised filter screen. This OEM part ensures proper fit and maintains your dishwasher's warranty coverage, unlike aftermarket alternatives that may not meet factory specifications.

When to Replace Your Sump Filter Screen

Replace this component if you're experiencing standing water after the drain cycle completes, if you can see visible tears or holes in the mesh, or if calcium buildup has reduced water flow through the screen. Most homeowners replace this part every 3-5 years as preventive maintenance, though hard water areas may require more frequent replacement. Don't wait until the drain pump fails — that repair costs significantly more than this simple filter screen.

Need Help Finding Your Model Number?

Having trouble locating your model number? It's stamped on a label or etched into the metal frame. Open your dishwasher door fully and look along the top edge of the door opening or on the side walls. Some models have the information on the inside of the door itself. Write down the complete model number including all letters, numbers, and dashes — partial numbers won't guarantee correct fitment.
