When I press the Start-Stop Button or Foot Controller, my machine makes a whirring noise, but the needle bar does not move.

Please check the Bobbin Winder.
If the Bobbin Winder shaft is moved to the right hand position (bobbin winding mode), the needle will not move.
Please return the Bobbin Winder Shaft to the left hand position and press the Start-Stop Button or Foot Control to start the machine.
