Washing machine and controlling method thereof

Abstract

Provided is a washing machine including: a memory storing instructions; at least one processor including processing circuitry; a drive device configured to drive the washing machine using a motor; a water supply device configured to supply water into the washing machine; a drain device configured to discharge water from the washing machine; and a sensor device, wherein, at least one processor, individually or collectively, is configured to execute the instructions and to cause the washing machine to: perform a water supply cycle in response to a command being received, obtain acceleration data and water level data from the sensor device, obtain a first acceleration from the sensor device based on a specified event related to the motor occurring, obtain a second acceleration in response to a current water level of the washing machine exceeding a threshold water level, perform a first draining cycle in response to the second acceleration exceeding a threshold acceleration, obtain a third acceleration in response to a wash cycle starting after the first draining cycle, and perform a second draining cycle based on a difference between the first acceleration and the third acceleration.
