Dialysis machines comprising a feed arrangement to supply a dialysis fluid to a dialyzer during dialysis treatment and a return arrangement to remove the dialysis fluid from the dialyzer during dialysis treatment and forward it to an exit; a feed recirculation circuit to allow a fluid of the feed arrangement to be re-circulated in a fluid loop path comprising, at least a portion of, the feed arrangement and the feed recirculation circuit and a return recirculation circuit to allow a fluid of the return arrangement to re-circulate in an auxiliary fluid loop path comprising, at least a portion of, the return arrangement and the return recirculation circuit. A controller configured to perform disinfection by re-circulating a disinfectant and/or a heated fluid through said fluid loop path and/or through said auxiliary fluid loop path. The dialysis machine further comprises a feed forward arrangement connected to the fluid loop path and arranged to enable a fluid of the feed arrangement to be forwarded to the exit by-passing the auxiliary fluid loop path.
