Agilent 6890 Faulty Pneumatic Board

[oscar.oyola@upr.edu]

Hi, I have a Agilent 6890 with MS detector, and I have problems with the EPC.

The message that display is : Pneu Error 0158
PCB Cmd Error: 2003

Anyone knows how to fix this?

Regards,

EPC's are a known weak spot of the 6890 and can be an expensive repair. From Agilent a new board is ~$2000. If you can remove the board there are 2 or so places that will fix them for under $1000 WN technical I believe is one.
