790 E pump won't de stroke

dimanche 6 septembre 2015

I have a 790 elc and we can't get the pump to completely destroke. We had the DP sensor go bad and as soon as we put in a new one everything went south. We consulted with the dealer and thought it could be a bad sensor, so they sent another.
We've checked everything (sensors,wire continuity, etc ) according to the shop manual, but no change.
The one thing that we can't confirm is the code on the PVC. It's flashing rapidly and continuously,and the book has no description of this message.
Does this mean the PVC is toast.
Does anyone have any experience with this situation?
