Abstract: A dishwasher may include a washing chamber, a door having a detergent dispenser, and a wash arm arrangement with a rotatable first wash arm and a second wash arm which may be rotatably attached to the rotatable first wash arm. The second wash arm may include a spray nozzle arranged to expel washing liquid in a direction relatively the second wash arm. The second wash arm may be arranged to bring the spray nozzle along a circular path with a radius in a plane during a rotation cycle of the second wash arm. The direction may have a first angle in the plane relatively the radius and a second angle relatively the plane, and the spray nozzle may be arranged to be directed in the direction towards the detergent dispenser during at least a portion of the rotation cycle to cause the washing liquid to intersect with the detergent dispenser.
