Abstract: A washing apparatus is provided. The washing apparatus includes a main body having a door, a spin basket disposed inside the main body and rotating about a rotary shaft, a motor providing power to the rotary shaft, a spring clutch including a first core rotating in conjunction with the motor and a second core rotating in conjunction with the rotation shaft, and selectively transmitting power of the motor to the spin basket, a processor, and a sensor that measures revolutions per minute (RPM) of the spring clutch, and when the driving of the motor based on an input signal is completed, the processor controls to stop the driving of the motor, and after stopping the driving of the motor, controls the motor to be re-driven for a preset driving time based on a measurement value of the sensor.
