Low air pressure has given me that message several times, and the fault has always been mine.

I have also had trouble with the drawbar solenoid needle valve lock nut coming loose, and the needle backing out.
The round, knurled, lock nut would suggest finger tightening.
The third time it came loose, I used pliers to tighten it and have not had another repeat of that problem.

I wonder if you have a similar problem with your tray solenoid valve?

I have a feeling that you're right.
The guy that I bought the machine from, is coming over next week and (hopefully) we'll find the problem.
I did mention what you had said and he seems to think that might be the problem.
I'll let you know.
