Hi, I assume the mechanical pump starts when you click vacuum.
If it does, how many times did you try this? Last time I did it, it took me 3 tries to finally achieve the necessary vacuum to start the turbopumps. Our oil is near the lower mark of the mechanical pump. I think it is related.
I'm not saying this is the best way to go, maybe there is a real problem and unsuccesfully trying to turn on the vacuum repetitive times would damage your ICP. But for us it has been kinda always like that.
I suggest checking the IF/BK pressure while doing it.
