A method for controlling a multilevel converter having a plurality of energy sources and a plurality of power converter modules, each power converter module comprising at least two switching elements is described. The method can comprise: selectively switching (S1) at least one of the plurality of power converter modules and/or at least one of the plurality of energy sources into a diagnostic state; in the diagnostic state, charging or discharging (S2) the at least one of the plurality of power converter modules and/or the at least one of the plurality of energy sources at a predetermined charge or discharge rate until a predetermined criterion is reached; and when the predetermined criterion is reached, selectively switching (S3) the at least one of the plurality of power converter modules and/or the at least one of the plurality of energy sources from the diagnostic state into a non-diagnostic state.
