This part is the replacement fine filter assembly for your dishwasher. It is made of white plastic and is approximately 7 inches in diameter with a spout that extends an additional 2 inches. The filter removes food particles and debris from the water in your dishwasher and prevents the drain from clogging. If the drain is clogged, the dishwasher is not draining, or your dishes are not being cleaned properly, you may have a damaged filter. This part is an authentic OEM part sourced directly from the manufacturer, and is sold individually.
