1. A washing machine comprising:
a washing machine door;
a washing machine inlet configured to be opened and closed by movement of the washing machine door;
a door lock switch module provided in the washing machine inlet to prevent separation of the washing machine door from the washing machine inlet and configured to include a door lock bolt movable to an inside of the washing machine door, a first switch that is closed when the door lock bolt moves to a locking position in which the door lock bolt protrudes to an outside of the door lock switch module, a second switch that is connected in series with the first switch and is closed when a magnetic body, included in the washing machine door, approaches the door lock switch module, a third switch that is connected in parallel with the first switch and is open when the door lock bolt moves to the locking position, and a moving contact mechanically interworked with the door lock bolt; and
a processor configured to control the washing machine to perform a washing process,
wherein the first switch includes a first switch contact and the third switch includes a third switch contact,
wherein when the door lock bolt moves to the locking position, the moving contact is in contact with the first switch contact so that the first switch is closed and the moving contact is not in contact with the third switch contact so that the third switch is open, and
wherein when the first switch and the second switch are both closed and the third switch is open, the processor identifies that the washing machine door is locked by the door lock bolt and controls the washing machine to perform the washing process.
