Claim 13:
14. A laundry treatment machine comprising:
a washing tub;
a driver to drive the washing tub;
a drain pump;
a motor to drive the drain pump;
a converter to output a direct current (DC) power;
an inverter to convert the DC power at a DC terminal into an alternating current (AC) power based on a switching operation and to output the converted AC power to the motor; and
a controller to change a dewatering entry time point based on a level of a lift, in response to drainage being completed,
wherein the lift is a difference between a water level of a water introduction part through which water flows into the drain pump and a water level of a water discharge part through which the water is discharged out of the drain pump,
wherein the controller is configured to perform power control of the motor in response to the drainage being started, and
wherein the controller is configured to terminate the power control of the motor in response to a residual water level being reached.
