Abstract:
1. A method of operating a dishwasher having a tub at least partially defining a treating chamber, a filter fluidly coupled to the treating chamber, and a rotatable sprayer located in the tub and spraying liquid in the treating chamber with at least one nozzle directed so as to pass over the filter during the rotation of the rotatable sprayer, the method comprising: spraying liquid from the rotatable sprayer within the treating chamber; recirculating the sprayed liquid from the treating chamber to the rotatable sprayer for subsequent spraying to define a recirculation flow path; and controlling the rotation of the rotatable sprayer to linger at a location relative to the filter where the at least one nozzle passes over the filter, as compared to rotation of the rotatable sprayer where the at least one nozzle does not overlie the filter, such that at least a portion of the sprayed liquid is focused on the filter within a single revolution of the rotatable sprayer.
