Dishwasher with auxiliary, tough soil chemistry dispensing system

A method of operating a dishwasher including a washing chamber, a dish rack for supporting kitchenware to be washed in the washing chamber with the dish rack being movable between an extended, loading position that is at least partially outside the washing chamber and a recessed, operational position that is within the washing chamber, at least one spray nozzle exposed to the washing chamber and a fluid conduit system for directing washing fluid to flow to the at least one spray nozzle during a washing operation, said method comprising:

• loading a storage compartment of a dispenser, mounted to the dish rack, with a washing agent;
• automatically, fluidly connecting an inlet of the dispenser to a port of the fluid conduit system upstream of the at least one spray nozzle upon retracting the dish rack into the recessed, operational position;
• and
• directing washing fluid to flow through the fluid conduit system toward the at least one spray nozzle during the washing operation, with only a portion of the washing fluid directed to the spray nozzle being diverted into the storage compartment of the dispenser and subsequently redirected, along with some of the washing agent, into the washing chamber from the dispenser.
