Abstract

A washing machine may include a tub; a drum configured to be rotatable inside the tub; a weight balancer coupled to the tub; a vibration sensor provided in the tub; and a controller, wherein the controller is configured to compare an unbalance value of laundry in the drum with a reference value based on a driving current applied to a motor configured to rotate the drum, obtain an angular speed of at least one rotation axis of the tub based on an output value of the vibration sensor in response to the unbalance value of the laundry being less than the reference value, and determine whether the weight balancer is damaged based on the angular speed of the at least one rotation axis of the tub.
