ABSTRACT:
A laundry appliance comprises a drum for receiving a load of articles. The drum comprises at least two rotatable drum portions and a drive which is capable of rotating the drum so as to cause relative rotation between the drum portions. A controller monitors and controls operation of the appliance. The controller is arranged to determine when there is an overload condition on the drive during a period when the drum portions are being rotated relatively to one another and, in the event of an overload condition, causes the drive to operate in a manner that alleviates the overload condition. The drive can abort the current drum action and begin the next drum action in the sequence and, after a predetermined number of overload conditions, can suspend counter-rotating drum operation. The user may be provided with an indication when an overload condition occurs.
