Abstract
A sequencing spray arm assembly includes a plurality fluid spray arms rotatably mounted on respective radially spaced carrier arms. The rotating fluid spray arms are in fluid communication with a fluid distribution manifold and adapted to distribute washing fluid throughout a washing chamber of the appliance. A sequencing diverter valve system enables delivery of washing fluid from the fluid distribution manifold to one or more of the plurality of rotating fluid spray arms. A fluid responsive rotating drive arm drives the rotation of a sequencing disk in the valve system between discrete positions and enables delivery of fluid to one or more of the plurality of rotating fluid spray arms in a sequential manner such that, for each discrete position, less than the total number of spray arms are supplied with washing fluid at a time.
