Abstract
A device and method for controlling a washing machine detects an amount of eccentricity of a tub of the washing machine and determines whether the degree of eccentricity is acceptable. The degree of eccentricity is measured by causing the tub to rotate at a substantially constant speed, and counting the number of times that the rotational speed of the tub changes during a predetermined period of time. The device and method determine whether a degree of eccentricity is acceptable based a comparison of the determined degree of eccentricity to one or more of a plurality of predetermined eccentricity reference values, and based on a number of times that the determination has been made unsuccessfully. The eccentricity reference values are selected based on a compensated laundry volume level. The compensated laundry volume level, in turn, is based on a detected laundry volume level, and a laundry volume compensation index that represents the number of times that the determined eccentricity value of the tub exceeds a predetermined eccentricity value during a predetermined time period.
