Abstract: A dishwasher appliance includes a tub defining a wash chamber. A first rack assembly is slidably positioned within the wash chamber. A first spray assembly is positioned in the wash chamber and configured to direct wash fluids at the first rack assembly. A second rack assembly is slidably positioned in the wash chamber above the first rack assembly. A second spray assembly is positioned in the wash chamber and configured to direct wash fluids at the second rack assembly. A third rack assembly is slidably positioned in the wash chamber above the second rack assembly. A third spray assembly is positioned over the third rack assembly and configured to direct wash fluid at articles located in the third rack assembly. The third rack assembly includes a wire framework defining a perimeter of the third rack assembly. A wire insert includes a wire floor portion that is defined between a first boundary wall and a second boundary wall.

Abstract: A dishwasher appliance includes a tub defining a wash chamber. A second rack assembly is slidably positioned in the wash chamber above the first rack assembly. A third rack assembly is slidably positioned in the wash chamber above the second rack assembly. A third spray assembly is positioned over the third rack assembly and configured to direct wash fluid at articles located in the third rack assembly. The third rack assembly includes a wire framework defining the shape of the third rack assembly. The wire framework incudes a boundary wall at a first side portion and a boundary wall at a second side portion. A wire insert includes a wire floor portion. The wire insert is configured to translate along one of the lateral direction and the transverse direction. The wire framework includes one or more detents configured to provide positional feedback when the plurality of hooks of the wire insert pass over the detents.

Abstract: A dishwasher appliance includes a tub defining a wash chamber for receipt of articles for washing and a guide assembly defined by the tub and including an upper guide and a lower guide spaced apart along the vertical direction to define a support groove having a retention geometry proximate a front opening of the tub. A rack is positioned within the support groove and is slidable along the transverse direction between a retracted position and an extended position, the rack defining a rear retention member that engages the upper guide at the retention geometry when the rack reaches the extended position.

Abstract: A dishwasher appliance includes a tub defining a wash chamber for receipt of articles for washing and a third rack assembly slidably positioned within the wash chamber and configured for movement along the transverse direction. The third rack assembly includes a perimeter support wire and a flat floor suspended from the perimeter support wire, the flat floor being formed from interwoven floor wire and defining a floor width that is greater than 70% of a tub width of the tub. The diameter of the perimeter support wire is about 0.17 inches, the diameter of the floor wire is about 0.06 inches, and both the perimeter support wire and the floor wire are formed from stainless steel or nylon-coated metal.

Abstract: A dishwasher includes a tub defining a wash chamber, a spray body positioned within the wash chamber of the tub, and a wash rack positioned within the wash chamber of the tub above the spray body along the vertical direction. The wash rack includes an expanded metal basket comprising a base panel and a plurality of side panels extending upwardly from the base panel, the expanded metal basket defining a basket volume, the base panel comprising a plurality of strands, and a plurality of integral tines extending from the base panel, wherein each of the plurality of integral tines is bent at a junction of the plurality of strands. Methods of making and using the wash rack are also provided.

Abstract: A variable position diverter that provides wash fluid to selected combinations of outlet ports and spray assemblies. The diverter includes a housing having a plurality of outlet ports and a valve disk having a plurality of apertures. The valve disk is rotated relative to the housing to align one or more of the plurality of apertures with one or more of the plurality of outlet ports to selectively control the flow of wash fluid through a plurality of spray assemblies. Selectively diverting wash fluid in this manner can improve wash performance and reduce cycle time while meeting government regulations regarding water usage.
