Example embodiments provide a dishwasher comprising a tub; a door configured for selectively sealing a forward access opening of the tub; a detergent dispenser located at an inner surface of the door; a spray arm mounted within the tub such that the spray arm is adjustable between a first height and a second height, the spray arm comprising a spray detergent nozzle; and a circulation pump configured to supply washing liquid to the spray arm. The dishwasher is characterized in that the spray arm is configured to emit a fan-shaped jet from the spray detergent nozzle when the washing liquid is supplied to the spray arm and the spray arm is configured to emit the fan-shaped jet that is incident upon the detergent dispenser both when the spray arm is positioned at the first height and when the spray arm is positioned at the second height.

Provided herein are a spray arm assembly and associated dishwasher. The spray arm assembly may include a spray arm and a satellite arm. The spray arm may have a body defining an inlet opening and an outlet opening spaced along the body, and the body may receive washing fluid at the inlet opening and direct at least a portion of the washing fluid to an outlet opening. The body may further define one or more fluid supply channels extending between and fluidly communicating the inlet opening and the outlet opening. The satellite arm may be rotatably coupled to the spray arm at the outlet opening, and a portion of the one or more fluid supply channels may extend past the outlet opening to direct at least a portion of the washing fluid past the outlet opening and back towards the inlet opening before entering the outlet opening.

The rotor of the invention has two legs fastened to a rotary base, wherein the legs are provided with asymmetrically arranged boreholes facing upwards and boreholes facing downwards, wherein the boreholes facing upwards have the shape of an ellipse, while the boreholes facing downwards have a circular shape. The boreholes facing upwards and the boreholes facing downwards are formed, such that the jets from the boreholes facing upwards act vertically upwards and the jets from the boreholes facing downwards act vertically downwards, i.e., in a direction 90° with respect to the axis of the legs.
