Did a quick check of the pumbing and the bleed valves (both LH2 and LOX) aren't solenoids, but are in fact pressure actuated valves, feed pressure to open from a single solenoid. So if the solenoid didn't open, the LOX bleed would also suffer, which doesn't appear to be the case. So that leaves the LH2 bleed valve not opening... which would be picked up by the engine controller.IMO, that's probably debris or for some reason the bleed valve solenoid didn't fully open...
