Abstract: A washing machine includes a controller. The controller perform switching processing, by moving a moving part in an axial direction so that the moving part is switched from a start state in which one of a rotor-side fixing part and a stator-side fixing part engages with the moving part to an end state in which a remaining one of the rotor-side fixing part and the stator-side fixing part engages with the moving part. The controller is further configured to perform an adjustment operation before the end state of the switching processing starts. In the adjustment operation, the controller is further configured to adjust an engagement position by changing a rotation phase of rotor so as to allow an engagement position of the moving part with respect to the remaining one of the rotor-side fixing part and the stator-side fixing part to become a target engagement position.
