Abstract
A pump and motor assembly for a dishwasher including a food particle macerating means having a cutting arm attached to a helically-wound column. The cutting arm coacts with a grid-like grading element to macerate food particles to reduce them to a size where they will be removed in fluid suspension with an initial rinse liquid in the dishwasher. The food particle macerating device is capable of riding over or slipping around unmacerable food particles, such as particles of bone, without damage to itself or to associated elements of the pump-motor assembly. The macerating device further serves to dislodge unmacerable particles from the grading element, urging them into a trap provided for their collection.
