According to embodiments of the present invention, a dishwasher may provide an intensified wash effect. The dishwasher may include a rack defining a bottom and a sidewall, wherein the rack is adapted to receive dishware therein. A dishwashing fluid supply channel may be configured to supply dishwashing fluid to a spray assembly. The spray assembly may comprise at least one nozzle member. Thereby, the spray assembly may be adapted to receive the dishwashing fluid from the dishwashing fluid supply channel and to dispense the dishwashing fluid therethrough. The spray assembly may be coupled to the sidewall of the rack. Further, the nozzle member may be attached to an arm which is moveable between at least a first position wherein the arm is adjacent the sidewall of the rack and a second position wherein the arm is adjacent the bottom of the rack.
