ABSTRACT:
A washing machine includes a perforated washing drum with a contact rpm at which items of laundry in the washing drum come to rest against a surface of the washing drum due to centrifugal force. The washing drum is intermittently driven in alternating rotary directions (reversing mode) during washing and/or rinsing, for accelerating the washing drum in one of the rotary directions to a first rpm being markedly below the contact rpm and accelerating the washing drum in the other of the rotary directions to a second rpm being markedly above the contact rpm.
