Abstract: Disclosed are a laundry treatment machine and a method of operating the same. The method of operating a laundry treatment machine includes rotating a drum at a first velocity, forcibly vibrating the drum using a forced vibration generation signal during a first velocity rotating section, and determining whether to accelerate or decelerate the drum after forced vibration. Through this method, laundry position may be determined.

Abstract: Disclosed are a laundry treatment machine and a method of operating the same. The method of operating the laundry treatment machine includes performing a primary sensing of an amount of laundry within the tub, supplying water to a first water level within the tub, sensing the level of water within the tub, performing a secondary sensing of the amount of laundry within the tub, and judging whether the laundry includes dry laundry or wet laundry using the primarily sensed amount of laundry, the secondarily sensed amount of laundry, and the sensed water level value. This method ensures efficient implementation of sensing of amount of laundry.
