Abstract: A dishwasher having a removable filtration system includes a main coarse filter screen having a central opening for removably fitting the filter screen around a water distribution manifold. The filter screen includes an outer circumferential rim portion have an elastomeric seal over-molded thereto which is press-fit into a channel in a lower sump unit such that the filter screen is suspended over a sump enclosure. A finer, secondary strainer extends through the filter screen and provides secondary filtering of washing fluid entering the sump enclosure through the filter screen. Preferably, the filtration system also includes a non-removable or backup strainer which provides coarse straining of washing fluid should a user fail to properly reinstall the removable filter screen and/or the secondary strainer.

Abstract: A modular exhaust vent for use in venting a wash chamber of a dishwasher, such as during a dry cycle, comprises a housing that forms an exhaust flow path from the wash chamber to the exterior of the dishwasher and a valve operable for pivotal movement about a pivot axis between an opened and closed position for selectively closing the exhaust flow path. An actuator for moving the valve is connected to the valve by a link such that activation of the actuator effects movement of the link to pivot the valve to either the opened or closed position. Further, the valve selectively closes the exhaust flow path at an inlet to impede introduction of sound into the exhaust flow path.
