Thi error literally is related to the deagser. I think if you have checked for the obvious fluidic problems, but just check the lines from the degasser seem tight and there are no obvious leaks. AFter that you have a degasser chamber failure or this this is an electronics issue. I think this will need a ervice call to be made to your local ervie representative.
How did you resolve the problem? I just have same problem with you. Thanks!
It required a service visit to replace the degasser unit.
This sounds like a weak vac. pump on degasser. The degasser wants to see the vac. reach a certain level and maintain it. These pumps wear out with age. Check degasser vac. in console. Ideally you should see a reading of .9 or less. Also these pumps often begin to make a faint clunking sound as the bearings start to go.
If you do repairs yourself pump not very difficult to change out. Part # 700001352.
