The frame includes a receiving portion. The hinge plate includes a depth positioning portion, which is received in a form-fit manner in the receiving portion of the frame to fix the hinge plate to the frame in a depth direction of the dishwasher cavity.

A dishwasher and method utilize an image-based position sensor that is positioned to sense the rotational position of a discretely directable tubular spray element driven by a tubular spray element drive.

A dishwasher with a tub that at least partially defines a treating chamber with an access opening, a closure moveable relative to the tub to selectively open and close the access opening, a lower dish holder located within the treating chamber, a middle dish holder located within the treating chamber above the lower dish holder, and an upper dish holder located within the treating chamber above the middle dish holder and having container supports defining a support surface.

A dishwasher appliance includes a tub. A leak pan is positioned below the tub. A leveling assembly is configured for adjusting a level of the tub. The leveling assembly includes a housing mounted to the leak pan. A leveling leg is positioned within the housing. The leveling leg has a foot. An axle is mounted to the leak pan. A gear set is positioned within the housing. The gear set is configured to transfer rotation of the axle through the gear set to the leveling leg to adjust the level of the tub. The foot of the leveling leg is spaced from a thread on an outer surface of the leveling leg such that the gear set unmeshes from the thread on the outer surface of the leveling leg when the leveling leg is fully retracted.
