A peritoneal dialysis machine has a machine housing and a drain pan for receiving one or more solution bags for storing consumed dialysate. The drain pan is connected to a weighing cell such that the weight of the drain pan can be detected by the weighing cell. A damping system prevents the occurrence of undue force introduction into the weighing cell. The damping system has a damper to which the drain pan is directly or indirectly fastened, and the damper is connected to the weighing cell such that the weight of the drain pan acting thereon is transmitted to the weighing cell.
