1. A method for operating an air jet spinning machine having a spinning unit with a spinning nozzle for producing a yarn, the method comprising: during operation of the spinning unit, feeding a fiber composite to the spinning nozzle through an inlet and in a predefined transport direction, wherein the fiber composite within a vortex chamber of the spinning nozzle receives a twist with the assistance of a vortex air flow, such that a yarn is formed from the fiber composite and leaves the spinning nozzle through an outlet; monitoring the yarn leaving the outlet with at least one sensor system with regard to defined yarn flaws; interrupting production of the yarn upon the detection of a corresponding yarn flaw; between detection of the specified yarn flaw and interruption of the yarn production, performing a cleaning process for a specified period of time during which an additive is fed to a location either within the spinning nozzle or upstream of the spinning nozzle and is applied to one or more of: (1) the fiber composite; (2) the yarn produced from the fiber composite; or (3) parts of the spinning nozzle.
