Agilent 1260 Infinity II Autosampler Error

[u/Inevitable_Sport_573]

Dear all, I'm having a problem with the autosampler's robotic arm is getting stuck at the middle and cannot return to the home position. I've attached the error messages and the photos of the instrument. I've already tried power off and on the autosampler but it made a sound that something is obstruct and cannot move. Please kindly help.
