The present disclosure discloses a washing machine and a method for fault determination for a stirring mechanism in a flocculation treatment process. The washing machine comprises a flocculation container (1) for flocculation treatment on washing water; the stirring mechanism driven by a motor (6) to rotate is arranged in the flocculation container (1); the motor (6) is provided with a current meter for detecting working current of the motor (6); and the stirring mechanism is provided with a rotating speed sensor for detecting the rotating speed of the stirring mechanism. The method comprises the following steps that when the washing machine executes a flocculation program, the stirring mechanism is driven by the motor (6) to work, working current I and/or power P of the motor (6) are detected, and rotating speed V of the stirring mechanism is detected; and when any one of detection values is beyond a corresponding setting range, a fault alarm signal of the stirring mechanism is given out.
