13. A dishwasher comprising:
-
a cabinet; a tub located within the cabinet and at least partially defining a treating chamber with a bottom wall having a liquid outlet; a sprayer located in the treating chamber above the bottom wall and having a plurality of spray nozzles through which a liquid is sprayed into the tub, with none of the spray nozzles spraying directly onto the tub liquid outlet; a housing physically separate from the tub and defining a sump to receive liquid sprayed into the tub, the housing having an inlet fluidly connected to the liquid outlet and an outlet fluidly coupled to the sprayer to define a recirculation path for the sprayed liquid; a filter located within the housing and fluidly separating the housing outlet from the housing inlet to filter liquid passing through the sump; and a wash pump, having an impeller, fluidly coupled to the recirculation path to pump the liquid from the sump to the sprayer; wherein the sump is located within the cabinet and remote from the tub such that the filter is not directly exposed to the tub and wherein the filter is mounted to the impeller of the wash pump to effect rotation of the filter. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20, 21, 22, 23)
