Hey, in the driver you can right click and do a manual needle wash (to wash the outside of the needle) outside of the method with certain samplers. What module number do you have GXXXX? Flushing the flow path would need to be done by manually changing the composition (to for example a higher organic percentage) to clean the injector.
