Abstract
A washing machine and method for operating a washing machine having a suds container for holding washing liquid, a non-ribbed drum rotatably mounted in the suds container for holding laundry, a motor for driving the drum, and an open or closed loop control device, wherein the method has a step for rearranging the laundry in the drum. The drum is caused to execute a right-left motion by means of the motor so as to cause a rocking motion of the laundry at a rocking frequency, the predetermined rocking amplitude of which is adjusted such that a laundry fall is implemented in which the laundry falls from a first region of the drum into a second region of the drum.

A method for operating a washing machine having a suds container for holding washing liquid, a non-ribbed drum rotatably mounted in the suds container for holding laundry, a motor for driving the drum, and an open or closed loop control device, wherein the method has a step for rearranging the laundry in the drum, in which the drum is caused to execute a right-left motion by means of the motor so as to cause a rocking motion of the laundry at a rocking frequency, the rocking frequency having a predetermined rocking amplitude which is adjusted such that a laundry fall is implemented in which the laundry falls from a first region of the drum into a second region of the drum, and wherein the rocking frequency is adjusted in the range of from −50% to +20% of a calculated rocking frequency stored in the washing machine, wherein the calculated rocking frequency stored is calculated using the following formula (1),
- f
- =
- g
- r

- π
- (
