Abstract
A dishwasher includes a pump assembly which functions to chop all fluid entrained soil prior to directing fluid to upper and lower wash anms. A flow conduit leading to the upper wash arm is provided with a sampling port which directs a percentage of the fluid flow into a filter chamber having one or more fine mesh filter screens that open into the dishwasher tub basin. The filter chamber is exposed to a collection chamber that leads to a flapper valve and then to a drain port. An overflow tube, which is in fluid communication with the filter chamber, extends upwardly within the dishwasher. When the fine mesh filter becomes clogged, fluid will be forced to flow up the overflow tube and be exposed to another filter. A filter guard is secured to a housing of the recirculation pump over portions of the fine mesh filter.
