A laundry treating appliance having a drum, defining a treating chamber, with a lifter and a balancing system having at least one balancing ring and a reservoir located in the lifter and a liquid supply system fluidly coupled to the reservoir. Liquid may be supplied to the ring and to the reservoir through the ring to offset an imbalance in a laundry load located within the drum.

A method of determining static and dynamic imbalance conditions in a horizontal axis washing machine utilizes a number of dynamic algorithms to automatically determine the total load size, the magnitude of any static load imbalance, and the magnitude of any dynamic load imbalance for any given load in a given washing machine based on power measurements from the washing machine motor obtained in predetermined speed profiles.

A method for controlling the spin cycle in an automatic clothes washer. The clothes washer comprises an imperforate tub, a perforate basket located within the tub, a bearing assembly carried by the tub, a drive shaft rotationally supported in the bearing assembly and coupled to the basket to define a rotational axis of the basket, a drive assembly rotating the drive shaft, and a controller operably to the drive assembly, with the controller controlling the drive mechanism to control the spin rate of the basket according to a spin cycle. The method comprises sensing a moment acting on the bearing, and controlling the spin rate of the basket in response to the sensed moment.
