A spray assembly for a dishwasher includes a fluid pump and a spray tower. The spray tower includes a lower stationary member and an upper rotatable member and includes a fluid cavity therein. The rotatable member has at least one spray opening adjacent its upper end. A spray nozzle directs a stream of washing fluid upwardly into the spray tower and moves the stream of washing fluid in a circular pattern. The stream of water engages the upper rotatable member of the spray tower and the upper rotatable member rotates in response thereto. One form of the invention uses a deflecting surface on the rotatable member for causing rotational movement of the rotatable member and for causing precession of the rotatable member. Another modification of the present invention utilizes a pair of intermeshing gears for causing precession of the rotatable member.
