Mine did this and would not clear the "no discs" error
Tried the take it out and tap it but no luck
So used clean hover pole , with smallest taper end into multi disc player taking care not to touch anything, after 30 seconds of suction took it out and gave it a blast with computer compressed air cleaner into multi disc unit . Repeated the Hoover suction again
Worked fine I think it must have got dust debris in there or got stuck and air and suction helped clear it
