Arcam alpha one cd player

First time poster, my alpha arcam one cd has been in the loft for at least 5 years, today I powered it up and found it showed disc on the front panel
Took the lid etc off and I saw the disc was not being lifted, I did it manually and it worked
Any idea what I need to replace?
I have played a whole cd to make sure it reaches all parts and used next and previous
