<p>A laundry treatment machine (100) and a control method thereof are provided. The laundry treatment machine includes a device driving unit configured to control a lock device (110) including a lock element (112), which locks or unlocks a lead assembly (30) and a top cover (20), and a lead (116), which moves along with the lock element (112), when the lead assembly (30) and the top cover (20) are coupled, wherein the device driving unit (240) includes a position detector, which, if the lock element (112) is moved from its initial unlock position to a lock position where it can lock the lead assembly and the top cover (20), determines whether the lead (116) is moved from its initial position to a predetermined position and outputs a first detection signal as the result of the determination, and a device controller (246), which determines that the lead assembly (30) and the top cover (20) are locked and outputs lock information if the first detection signal is received, and which determines that the lead assembly (30) and the top cover (20) are not locked and outputs lock error information if the first detection signal is not received. Therefore, it is possible to easily determine whether laundry is stuck between the lead assembly (30) and the top cover (20) and whether the motor (114) is broken by locking or unlocking the lead assembly (30) and the top cover with the use of the lock element.
