The present disclosure relates to a laundry treatment machine. According to an embodiment of the present disclosure, a laundry treatment machine includes a controller controlling a motor, during dewatering, to be driven at a first speed when a lift is at a first level and to drive the motor at a second speed greater than the first speed when the lift is at a second level greater than the first level, wherein the lift is a difference between a water level of a water introduction part through which water flows into a drain pump and a water level of a water discharge part through which the water is discharged out of the drain pump. Accordingly, noise or vibration can be reduced even if the lift is changed during the dewatering.

A laundry treating apparatus includes a cabinet for forming an appearance of the laundry treating apparatus, wherein the cabinet has a laundry inlet defined therein, a drum disposed inside the cabinet, wherein a drum opening in communication with the laundry inlet is defined in the drum, wherein the drum accommodates laundry therein, and a control unit disposed in the cabinet to receive a control signal. The control unit includes a touch portion for forming an exposed surface outwardly of the cabinet, a circuit board spaced apart from the touch portion and positioned inside the cabinet, and a spring unit having a portion on one side in contact with the touch portion and a portion on an opposite side coupled to the circuit to connect the touch portion and the circuit to each other. The spring unit transmits an electrical signal input through the touch portion to the circuit board.
