Abstract: A method for controlling a laundry treating apparatus includes a dry cloth sensing operation of sensing an amount of clothes put into a drum, a wet cloth sensing operation of sensing a washing load based on a moisture content of the clothes by supplying water into a tub, and a cloth material sensing operation of sensing a cloth material of the clothes put into the drum based on a rpm gap and a motor-constrained state where rotation of a motor is restricted. The rpm gap is a difference between a target rpm of a rotator in the drum and an actual rpm of the rotator.

Abstract: A washing machine and a method for controlling a washing machine are provided. The method may include sensing an amount of laundry in an inner tub, configuring an operation setting based on the amount of the laundry sensed, supplying water into the inner tub and obtaining a preliminary water supply time taken for a water level within an outer tub to reach a predetermined preliminary water supply level, spraying the water from the outer tub into the inner tub through a circulation nozzle by driving a pump and obtaining a change of water level within the outer tub as the water is sprayed through the circulation nozzle, adjusting the operation setting based on the preliminary water supply time obtained and the change of water level obtained, and performing a washing operation based on the adjusted operation setting.

Abstract: A method for controlling a rinsing cycle of a washing machine is provided. The method may include a primary rinsing by supplying water into the inner tub until a water level in the outer tub becomes a preset circulating water level, wherein some of the water is supplied through a drawer in the washing machine that holds fabric softener, and a remaining amount of water is supplied by spraying the water supplied from the external water source through the direct water nozzle via a direct water supply hose, a secondary rinsing by spraying water into the inner tub through the circulating nozzle, and a third rinsing by spraying the water into the inner tub through the direct water nozzle while draining the outer tub.
