Abstract
A fine filter assembly for a dishwasher includes a filter body having an inlet and an outlet located substantially adjacent to one another, and an extended flow path joins the inlet and the outlet so that essentially an entire length of the filter body is used for filtration. The flow path is sloped from the inlet to the outlet and extends substantially 360 radial degrees around a circular outer perimeter of the filter body. Therefore, wash fluid naturally flows from the fine filter inlet to the fine filter outlet all the way around the filter body, and substantially the entire filter body is flushed when the fine filter is drained and a main pump assembly is energized.
