Claim 5:
6. The laundry treatment machine of claim 1, wherein while the speed of the washing tub increases before the washing tub motor is rotating at the constant speed, the controller is configured to control the drain motor to operate in a fourth period during which the speed of the drain motor increases, in a fifth period including a period in which the speed of the drain motor decreases after the fourth period, and in a sixth period during which the speed of the drain motor decreases after the fifth period,
wherein the controller is configured to control the drain motor such that a magnitude of the falling slope of the speed waveform in the fifth period is less than a magnitude of the falling slope of the speed waveform in the sixth period.
