Claim:
An automatic dishwasher comprising: a tub at least partially defining a wash chamber; at least one rack located within the wash chamber for receiving utensils to be washed; a rotating spray arm located adjacent the at least one rack and having at least one outlet emitting liquid directly toward the at least one rack to define a first spray zone that is directed into the at least one rack, at least one other outlet emitting a stream of liquid along a first path away from the at least one rack and radially beyond a circle defined by an outermost point of the rotating spray arm over one revolution of the spray arm; a disperser located within the wash chamber radially exterior of the circle and in direct alignment with the stream of liquid for at least a portion of one revolution of the rotating spray arm and where the stream of liquid is transferred from the at least one other outlet of the rotating spray arm to the disperser, and the disperser is configured to redirect the transferred stream of liquid onto a second path, different from the first path, toward the at least one rack to form a second spray zone directed to the at least one rack; and a liquid volume controller operably coupling the rotating spray arm and the disperser to control a volume of the stream of liquid that is transferred from the rotating spray arm to the disperser.
