Büchi vacuum controller B-168 error 3

Hi everyone,

I try to repair a vacuum distillation unit (B-172) from Büchi. I solved a lot of problems but the last is the controller (B-168). When I was dealing with the other parts, the controller seamed to work (I haven't tested, but he didn't said any error message). Now, he says "error 3" when I turn on the apparatus. I'have tried with other Solenoid Valve, from an other vacuum unit and it said "error 3" to. So I think that the problem's only the controller and not the other thinks that I had repaired. The manual is unfindable on internet.
Did any one know what "error 3" means or have the manual?

Thank you and have a nice day.
