DISHWASHER PRESSURIZED FINE FILTER ASSEMBLY WITH HELICAL FLOW PATH

A fine filter assembly for a dishwasher includes a filter body having a soil accumulation trough. The soil accumulation trough defines a substantial ly helical flow path between a fine filter inlet and an outlet. A natural flow path is therefore provided to efficiently clean fine the filter assembly with downwardly directed fluid jets generated by a lower spray arm assembly. Soil is directed to a fine filter drain tube with relative ease, thereby facilitating use of more efficient use of a drain pump inlet as a soil collection chamber during wash cycles.
