A wash arm arrangement (20) for a dishwasher is disclosed which has a central arm (21) adapted to be rotatably connected with a first shaft (23) through which liquid under pressure is fed into said central arm during operation. A satellite arm (22) is rotatably connected with a second shaft (24) arranged on the central arm, and which is arranged separated a first radial distance rcs from the axis of rotation of the central arm. The second shaft supplies liquid to the satellite arm during operation. To provide the liquid to a washing area of the dishwasher, the satellite arm comprises at least one outer nozzle (25) for providing liquid to a washing area of the dishwasher. The centre of the outer nozzle is arranged at a second radial distance rn with respect to the axis of rotation for the satellite arm which is at least equal to the first radial distance rcs minus half the width of the nozzle in a radial direction, and at most equal to the first radial distance rcs plus half the width of the nozzle in a radial direction. Thereby, an alternative and improved wash arm arrangement which has a high coverage of the washing area is achieved.
