Embodiments of the present invention provide systems, methods, and apparatuses for providing dedicated spray coverage for silverware and dishware positioned within a silverware basket. In an example embodiment, the dishwasher includes a tub configured to receive dishware and a circulation system configured to circulate fluid within the tub. The dishwasher further includes a silverware basket disposed within the tub and comprising a handle portion and a basket portion. The basket portion is configured to receive dishware therein. The handle portion defines at least one spray jet opening that is configured to be in fluid communication with the circulation system and configured to direct fluid toward the basket portion.

Embodiments of the present invention relate to methods and systems for detecting and removing a clogging condition of a filter in a dishwasher. According to one embodiment, the method includes determining a normal water level or a normal rate of water level change for a wash cycle of the dishwasher and monitoring a water level or a rate of water level change during execution of the wash cycle. The method further includes detecting the clogging condition of the filter by detecting a deviation thereof. A current position of the wash cycle being executed may then be determined. The method further includes executing a remedial operation to facilitate removal of the clogging condition and determining if the clogging condition has been removed. Finally, the method includes resuming operation of the dishwasher at a wash cycle position based on the current position if the clogging condition has been removed.

According to embodiments of the present invention, a dishwasher may include a manifold assembly including a manifold and an attachment assembly. The manifold may provide a fluid connection with a fluid supply and direct fluid from the fluid supply to a spray device. The attachment assembly may couple the manifold to a dish rack. Further, the attachment assembly may facilitate movement of the dish rack relative to the manifold between a retracted position and an extended position while maintaining the fluid connection with the fluid supply. The attachment assembly may include at least one sliding rail and a first plurality of engagement members that couple the sliding rail to the dish rack. Additionally, a second plurality of engagement members may couple the manifold and the sliding rail so as to allow movement along the sliding rail along a major axis of the sliding rail.

A spray arm feed tube assembly for a dishwasher is provided, comprising an elongate tubular member adapted to extend from a sump of the dishwasher, through an interface, and along a tub wall of a tub portion disposed outwardly of the sump. A banding member is operably engaged with the tubular member about the interface, wherein the banding member is adapted to cooperate with the tub portion and at least one separator member, about the interface, to prevent particulate matter from passing into the sump from the tub portion about the tubular member. An associated apparatus and method are also provided.

A screening arrangement for screening washing fluid in a dishwashing appliance is provided. Such a screening arrangement comprises intersecting wall members forming a latticework structure, defining opposing inlet and outlet planes, for receiving the washing fluid therethrough. The wall members have inlet and outlet ends disposed toward the respective inlet and outlet planes. The wall member inlet ends, in cross section, have a non-planar apex portion tapering toward the outlet plane. A circumferential member extends about a periphery of the latticework structure, and at least a portion of the circumferential member is sloped toward the latticework structure so as to direct washing fluid received thereby toward the latticework structure. An associated apparatus is also provided.

A drain valve for a dishwasher and associated apparatus and method are provided. A housing receives fluid through an inlet channel and channels the fluid toward an outlet channel extending from an outlet port defined by the housing. A sealing member is disposed within the housing and is capable of forming a sealing engagement with the outlet port. A cradle member disposed within the housing is configured to receive and partially constrain freedom of movement of the sealing member. The cradle member is movable between a valve closed position, where fluid flow toward the outlet channel urges the sealing member into sealing engagement with the outlet port to close the drain valve, and a valve open position, where fluid flow is allowed between the inlet channel and the outlet channel, through the housing, without the sealing member engaging the outlet port.

A spray arm for a dishwasher is provided, comprising a first portion having a first engaging surface extending about an outer surface periphery thereof, and a second portion having a second engaging surface extending about the outer surface thereof and complementarily configured with respect to the first engaging surface. The engaging surfaces form a laterally-extending, non-linear interface upon engagement such that the first and second portion outer surfaces are directed away from each other. The second portion also includes a flange extending about the outer surface, and disposed laterally outward of and spaced apart from the second engaging surface, to define a channel having a depth extending across the interface. A securing material is introduced into and substantially fills the channel, and extends across the interface and about the first portion outer surface periphery, to secure the first and second portions together. An associated method is also provided.

A tubular manifold device for a dishwasher and associated method are provided. The manifold device defines a contiguous interior channel between opposed inlet and outlet ends. The manifold device has an inner surface defining the interior channel and an opposing outer surface, and comprises at least two discretely-formed manifold portions, each extending between and at least bisecting the opposed inlet and outlet ends of the interior channel. The at least two manifold portions are capable of cooperating via respective engagable longitudinal edges so as to form at least two joints therebetween. At least one overmold member is configured to sealingly engage the at least two manifold portions, across each of the at least two joints, such that the interior channel is fluid-tight between the inlet and outlet ends.
