An adjustable rinse additive dispenser is provided for a dishwasher having a washing compartment and a door pivotal between a horizontal open position and a vertical closed position. The dispenser includes a rinse additive reservoir mounted on the door. A conduit provides a fill opening for adding rinse additive to the reservoir. A knob assembly includes a shaft extending into the conduit so as to substantially seal the opposite ends of the conduit, and defines an annular chamber within the conduit. A trough is provided in the reservoir for holding a fixed quantity of rinse additive. A passageway provides communication between the trough and the annular chamber, and is normally closed by a plunger assembly. During the last rinse cycle of the dishwasher, the plunger assembly is moved to an open position so as to allow rinse additive to flow from the trough into the annular chamber. A leak path is provided in the knob assembly so as to allow a selective amount of rinse additive to flow from the annular chamber into the washing compartment of the dishwasher. The quantity of additive dispensed from the annular chamber can be varied by turning the knob assembly such that the angular position of the leak path is raised or lowered.
