Claim:
1. A dishwasher comprising: a first tub at least partially defining a first treating chamber; a second tub at least partially defining a second treating chamber and where the first and second treating chambers are fluidly isolatable from one another; a recirculation system comprising a first recirculation circuit for recirculating liquid for the first tub, a second recirculation circuit for recirculating liquid for the second tub, and a single recirculation pump having an inlet fluidly coupled to the first and second recirculation circuits and an outlet selectively coupled to the first and second recirculation circuits; and a single bulk treating chemistry dispenser having multiple charges of treating chemistry, located between and fluidly isolated from the first and second treating chambers, and fluidly coupled to the first recirculation circuit via a dispensing conduit, wherein the treating chemistry is dispensed into the first recirculation circuit, and the recirculation system directs the dispensed chemistry to the second treating chamber by selectively coupling the outlet to the second recirculation circuit.
