Help Please: Gaggia syncony compact digital problem

[srv]

My machine had a blocked brew group message and slow motor. It finally turned the brew group enough to remove it. I then replaced the power transistor and a burnt up MOV and the motor turns normally however the brew group gear doesnt return to the home position. I replaced one of the two gear box microswitches and the gears are not broken. Replacing the microswitch didn't change anything. When turned on the brew gear turns till it hits the microswitch reverses direction but goes too far by a mm or 2 and the brew group cant be installed. Any suggestions on what this could be would be helpful. I was thinking the motor is running too fast or the main board is bad. I am not sure if the second microswitch would cause this issue.

thanks
