A nozzle for a liquid dispenser that incorporates a cleaning probe capable of removing foreign debris from a nozzle discharge passageway. The cleaning probe is moveable between a retracted position that permits fluid flow to a discharge orifice terminating the discharge passageway and an extended position in which the cleaning probe extends into the discharge passageway. As the cleaning fixture advances from the retracted position to the extended position, foreign debris present in the discharge passageway is displaced and ejected out of the discharge orifice.
