How to Clean Your Dishwasher Filter

DISHWASHERS are marvels of convenience until they stop cleaning your plates and start leaving grit behind. Most people blame the detergent or the machine's age, but the culprit is almost always the filter trapped at the bottom of the tub. Over time, bits of food, grease, and mineral deposits clog this mesh, causing the machine to recirculate dirty water rather than washing your dishes clean. Performing this maintenance once a month takes less than ten minutes and transforms your dishwasher's performance immediately. A clean filter allows for better water flow, quieter cycles, and less wear on your pump. When done well, your glassware will come out sparkling, and you will eliminate the musty odor that often signals a neglected filter.

1. Access the Filter First. Pull the bottom dishwasher rack out completely and set it aside on your counter or floor. This gives you clear access to the base of the machine where the filter assembly is located.
2. Unlock and Lift Out. Locate the cylindrical filter housing at the center of the bottom floor. Grip the plastic handle, rotate it a quarter-turn counter-clockwise, and lift it straight up.
3. Split the Filter Stack. Most systems consist of a cylindrical mesh filter and a secondary flat screen beneath it. Gently pull these apart according to your specific model's locking tabs.
4. Scrub Away the Grime. Take the pieces to your sink and use hot water, a mild dish soap, and a soft-bristle scrub brush. Focus on the fine mesh screens where grease and food particles hide.
5. Clear the Well Completely. Before reinstalling the filter, wipe out the circular well at the bottom of the dishwasher with a damp paper towel. Use a toothpick to pick out any solid debris stuck in the drain hole.
6. Lock It Down Tight. Place the pieces back into the bottom of the tub, aligning the notches perfectly. Twist clockwise until you feel a firm click or resistance to lock it in place.
