Whirlpool Dishwasher Noise Filter (W11643383)

The Whirlpool Dishwasher Noise Filter helps reduce sound from the wash system by filtering water and limiting debris from reaching moving parts. It sits in the sump area and works with the pump and spray system to keep water flow steady and help the dishwasher run with less noise. Common causes of failure include buildup of food soil and mineral scale, damage from hard objects, poor seating after cleaning, or wear that leads to cracks, warping, or a loose fit. When the filter clogs or no longer seals correctly, water flow can change and the wash system may sound louder than normal. These symptoms can help you decide if replacing this noise filter may address your issue: New or increasing grinding, rattling, or buzzing sounds during wash or drain Dishwasher gets louder over time, especially during circulation Debris found in the sump area or around the filter opening after a cycle Water flow seems reduced, with weaker spray action or poor cleaning results Filter appears cracked, warped, loose, or will not lock or sit flat Frequent need to clean the filter to keep noise down
