Abstract (en)

A washing machine (11) comprises a drum (28) for washing laundry therein, a drive motor (30) for the drum, and a drum receiving container in which the drum is arranged rotatably about an axis of rotation. Protrusions (42) are provided on the inside of the circumferential wall of the drum receiving container, each protrusion having a closable inside space which is accessible by openings (45). The openings can be opened and closed by controllable closing means (48). A washing machine control is connected with the pump (21) and with a drive motor control for the drive motor of the drum. The rotational position of the drum is exactly determined. An unbalance is detected and located exactly. By letting water out of one or more of the protrusions in defined manner, the unbalance can be reduced or even eliminated.
