摘要： A washing appliance includes a drum that is rotationally operable within a tub about a vertical rotational axis. An impeller is positioned within a lower portion of the drum and is rotationally operable about the vertical rotational axis. The impeller includes a plurality of flow channels that extend below the impeller and between the impeller and the tub. A receiver is positioned at a top of the impeller and includes apertures that are in communication with the respective flow channels. A filtering cap is disposed on a top of the receiver and positioned within a medial horizontal level of the tub. The filtering cap includes inlets that direct a toroidal flow into a removable particulate chamber positioned within the filtering cap. The toroidal flow is further directed through the respective flow channels to continue through the toroidal flow within the drum.
