Abstract
A soil separator for a dishwasher is provided in which the recirculating wash liquid flow through the dishwasher is divided into two flow streams and the soil separator is positioned in one of the flow streams. A screen blocks passage of large soil particles and directs then into the flow stream leading to the soil separator. An elevated dam in the soil separator blocks passage of lighter-than-water particles and a weir blocks passage of heavier-than-water particles. A V-shaped notch in the weir permits flow from the soil separator to rejoin the other flow stream.
