Yes, it was stuck on the seat of the solenoid and wouldn't allow it to seal and shut off the gas flow. Even turning the gas supply off and on during the ascent and after surfacing wouldn't dislodge it. I had to remove the solenoid and take the entire thing apart to remove it. There is an inline filter that can be installed by ISC that is supposed to prevent this but I don't have that filter installed. It's on my short list of things to have done right along with the latest software update. I'm also going to install an inline shutoff on the O2 injection hose, like the one on the ADV, so if something like this ever happens again I won't have to mess with feathering the tank valve. I just shut off the slider and use the manual add button.
