A beverage preparation machine (1) has: a housing (5); a duct (10) with an outlet (15); a conduit (20) upstream the duct and connected thereto; and a waste liquid collector (30) arranged to collect waste liquid from the outlet. The duct has: an operative position for circulating beverage through the conduit and dispensing said beverage from the outlet outside the housing above a user-receptacle filling area (35); and a cleaning position for circulating cleaning fluid through the conduit and evacuating said cleaning fluid from the outlet inside the housing to the waste liquid collector. The duct is pivotally assembled about a pivoting axis (11) to the conduit for pivoting the outlet between the operative position and the cleaning position.
