Abstract

A laundry appliance, such as a washing machine, comprises a drum for receiving a load of articles to be laundered. The drum comprises at least two rotatable drum portions and a drive which can rotate the drum portions relative to one another. A controller causes the appliance to perform a laundering cycle which includes a spin cycle in which the drum is rotated at high speed. Before the spin cycle, the controller detects whether there is an imbalance of the load in the drum and, in the event of an imbalance, the controller causes the appliance to redistribute the load by causing the drive rotate the drum portions relative to one another. In the event of a continued imbalance, the controller can repeat the redistribute operation or it can limit the spin speed during the spin cycle.
