Abstract
A soil separator for a dishwasher includes a centrifugal soil collection wall surrounded by a spill over guide channel, surrounded by a shallow annular accumulator channel. The soil accumulator channel is open to the dishwasher chamber but covered by a filter screen. An accumulator sump is arranged below the accumulator channel. The accumulator channel is partially formed by a plate or grating provided with spaced radial slots to allow soil to drop into the accumulator sump as it progresses around the accumulator channel. The shallow accumulator channel allows water to flush soil from an inside of the screen to the accumulator sump.
