A dishwashing appliance is provided herein. The dishwashing appliance may include a tub, a sump, a chamber pump, a vane, and a threaded engagement joint. The chamber pump housing may be mounted within at least a portion of sump. The chamber pump housing may define an inner wall surface. The vane may be positioned within the chamber pump housing. The vane may extend from an inner radial end to an outer radial end. The vane may define a foil profile. The threaded engagement joint may include a first radial thread profile and a second radial thread profile. The first radial thread profile may extend radially from the vane at the outer radial end. The second radial thread profile may be formed on the inner wall surface. The second radial thread profile may be complementary to the first radial thread profile.

A dishwashing appliance or variable spray assembly, as provided herein, may include a manifold body, a diverter valve, and a driver. The manifold body may define a fluid inlet, a first flow path, a second flow path, a first spray outlet, and a second spray outlet. The first and second flow paths may be downstream from the fluid inlet. The second flow path may be in fluid parallel to the first flow path. The second spray outlet may be spaced apart from the first spray outlet. The diverter valve may be mounted within manifold body and movable between a first zone position directing wash fluid to the first flow path and a second zone position directing wash fluid to the second flow path. The driver may be disposed outside of the manifold body to motivate the diverter valve between the first zone position and the second zone position.

A warewash machine includes a chamber for receiving wares, the chamber having a spray zone with an associated spray system for spraying liquid onto wares passing therethrough and a collection tank below the spray zone. A strainer pan is located atop the collection tank and includes an optional first opening with an optional removable strainer bucket mounted therein and a second opening with a removable cutlery basket mounted therein. A method of washing cutlery with such a warewash machine is also described.

The present invention relates to a dishwasher, comprising a rack wherein the dishes are placed; a body that is disposed at both sides of the rack ; a carrier on which the body is mounted, and an arm that is disposed on the body, that has a lock opening position that enables the body to be moved on the carrier when moved towards the rack by applying force and that has a locking position that enables the rack to be kept at the desired height by the position of the body being fixed on the carrier in the situation when the external force is not applied.
