The Alarm 18 typically is due to a self-locking joint on the revolver between the gear and the shaft of the revolver, normally this joint need to be replaced code 20892. You can check this problem, looking when error 18 is present if the locking piston of the revolver is aligned with the hole in the revolver or if it is shifted enough to do not enter in that hole. If yes 90 % is because of the locking joint. In case also read A18 annex.
- the alarm 14 is normally due to some different possible reasons; read please the A14 &A02 to have an idea about possible reason.
