IPF8300 error 03130031-2F25

Hi all,
Today I replaced Carriage Relay PCB, Head Management Sensor and Multisensor because I had error 2F48.
After I put everything back I turned on the printer and I heard a strange sound in right side of the printer (crrr crrr crrr), the carriage started to move from middle to right and and threw the error 2F25.
Now everytime when I power on the printer, carriage is moving to the left a little bit then is returning back to home but is not locking, after I power off the printer I can push it to the left.
Prior to replace the Carriage Relay PCB I unlocked it manually.
Any idea what it could be?

By now what I found is the carriage is hitting, with the left printhead housing (printheads are not installed), into the purge unit (see photo).
For some reason the carriage was let down by 1-2mm. If I push down the purge unit I can move manually the carriage into the correct position. If I lift a litle bit the carriage I can push it back to the correct position.
Now my question is how to adjust the carriage position if I can not enter in service mode?
Should I put back the old head management sensor or multisensor?
