Saeco Royal brew unit?

I have a Saeco Royal Professional coffee machine. It said brew unit block so I followed a video of how to remove the unit and replace but I cannot put the brew unit back in now because the gear is in the wrong position. How do I move the gears to the correct position? On their video(different machine) they held the button down with folded paper to make the machine think the brew unit is in then put the drip tray back in, shut the door and turned on. You could hear the gears moving. My machine does not do this.
