Clean a removable dishwasher filter carefully.

A dishwasher filter catches food particles so they do not circulate back onto dishes. Some machines use a removable manual-clean filter, while others have a different system. Begin with the model’s Use and Care Guide. Only remove a filter when the manufacturer’s instructions show that it is designed for homeowner cleaning.

What you’ll need

• Dishwasher Use and Care Guide
• Soft sponge or cloth
• Soft-bristle brush
• Warm running water
• Clean towel

Take it step by step

1. Empty the dishwasher and let hot surfaces cool. Pull out the lower rack to see the bottom of the tub. Compare what you see with the filter diagram in your model’s manual before touching any parts.
2. Follow the manual’s removal direction exactly. On Whirlpool’s common two-piece system, the upper assembly turns one-quarter turn counterclockwise before lifting out, and the lower filter then lifts slightly and pulls forward. Other models may differ.
3. Rinse the removable filter under warm running water until loose soil is gone. For stubborn residue, use a soft brush. Do not use a wire brush or scouring pad because abrasive tools can damage the filter.
4. Rinse away all soap and debris, then air-dry the filter or pat it with a clean towel. Look for cracks, torn mesh, or distortion before reinstalling it.
5. Return each piece in the order shown in the manual and lock it into place. Whirlpool warns not to run the dishwasher without its filters installed correctly; a freely turning upper assembly may not be locked.

When to ask for help

Stop and seek appliance help if the filter will not release with the manual’s method, glass or sharp debris is present, a part is damaged, or the assembly will not lock securely.
