Abstract A dishwasher having a holder for holding silverware to be washed rotatably mounted on a dish holding rack in the washing chamber. The silverware basket is rotated on the dish holding rack so as to permit subjecting silverware carried thereby to a spray of washing liquid, with the spray striking the silverware in different angular positions as the silverware basket revolves. The spray itself may have movement relative to the dish holding rack and silverware holding basket, and in the illustrated embodiment is provided by a rotating spray arm. Further, in the illustrated embodiment, the rotation of the silverware basket is effected by a supplemental spray acting against vanes on the rotatable silverware basket.
