Headspace PCM flow error and unsuccessful Steam Clean.

I'm getting a PCM C aux flow shutdown on 6890 with G1888. I am not getting flow from transfer line. Last time we saw this error, there was a colum restriction so I baked the GC and it resolved the issue. This time a GC bake was not successful. I tried to run a "Steam Clean" on the headspace per Agilent's procedure, but it will only load the first six vials before waiting for "GC ready". How do I bypass GC Not Ready for Steam Clean & could my issue be something other than a restriction on the headspace?
