Claim 5:
6. The method according to claim 1, wherein, in switching positions, in which an operating-mode setting device is on “filling and cleaning the eccentric screw pump”, pressure changes detected by the at least one pressure sensor up to a limit value are ignored by the control device and, in said switching positions of the operating-mode setting device, the drive unit is operated at a constant rotational speed or a constant power which is greater than 0% and at most 50% of a rotational speed or power with which the drive unit operates in a normal mode and, in said switching positions of the operating-mode setting device, the drive unit is switched off if the limit value is measured at the pressure sensor or at one of the pressure sensors.
