Abstract: The present disclosure relates to a laundry treatment machine and a method for controlling the same. A pump motor may operate according to the steps of starting up the pump motor when operating or stopping the pump motor. Upon restarting, the pump motor may be controlled to start up after being on standby until the rotor stops, and therefore the pump may run normally even in case in which the pump repeatedly stops and runs, and the drainage performance may be improved and wash water may be drained by the operation of the pump regardless of the lift level.

Abstract: The present disclosure relates to a laundry treatment machine. A pump motor provided in a drain pump is controlled to correspond to the operation of the main motor and the water level, so that the pump motor slows down based on the speed of rotation of the main motor and the water level and keeps operating at low speed. Therefore, the pump motor is able to keep operating without stopping operation, and the amount of noise caused by the start-up of the motor is reduced, and the time taken to align the rotor of the motor in position is reduced, thereby reducing drainage time and improving the drainage performance of the drain pump.

Abstract: The present disclosure relates to a laundry treatment machine and a method for controlling the same. An increased amount of wash water during dewatering is introduced into a pump by decreasing the speed of a pump motor provided in the pump and increasing it again based on changes in the speed of the main motor during dewatering, and the wash water introduced while the speed of the pump motor is increasing is drained. Thus, the amount of noise generated during drainage may be reduced, drainage performance may be improved, and drainage time may be shortened.
