It's correct for the Serial Number according to SIS. Fits everything up to 9XG1824. The machine itself dates from 1997.KS is that schematic from a 615?
Actually the Air Dryer Gp is listed as an Attachment (option) so it might be that this particular machine doesn't even have one. The system isn't exactly specific regarding whether it does or not.
That may have something to do with the problem. Who knows.?And if it does have a dryer, I seriously doubt it's ever been serviced.
