Fendt 820 error A.1.F3

Hi can anyone point me in the direction to putting this error code right? Can’t unlock spools, was working fine then just went all of a sudden. There’s Plenty of oil in the hydraulic tank.
Many thanks

Could be a small filter blocked that is doing this. On the 22bar system.

Have u tried the 2 buttons on the dash. Cant remember which 1s it is but theres 2 u press simultaneously on an 820 i drove when the spools played up

I can make the error go away but still can’t unlock spools
