Help please!! S9 starting out on MAX pressure?!?

[Hellosleep34]

Hello all, thank you and advanced! I just recently cleaned my S9. I took off the case and lightly and blew it with an air hose softly to get off all dust. I put it back together and confirmed all my settings were still there. When I turn it on now it starts out at Max Pressure and unable to breathe through it. The pressure is so high through my nasal mask I have to take off because I can't breathe. It feels like 25 psi going through your nose!!. I disconnected it and even restored default settings. I even re-entered my min pressure at 4 and maximum pressure at 7. When I click the start button it instantly starts out on a max pressure and feels like 25. 
I could really use some help and unable to know what else to do?? I received this from a hand-me-down of my dad and have the settings readjusted for mine. I don't even know where to take it or what to do if I can fix it any help would be very much appreciated. Prior to this it's been working great and no issues.

Sincerely,

T

I bet you might leave it dirty next time. It looks like the case is coming off again. I'm guessing, but I hope it's just the flow sensor wire, that has been disconnected?
There are some strip down and reassemble threads and possibly videos on youtube.

Thanks for the quick reply Ajax! 
Right!!! Funny...Is this something that's connected to the motherboard then? When I took the case off the only thing that was connected to the motherboard was the power supply that I saw. There's a video on YouTube that kind of shows house do take apart and I did this extremely carefully. https://youtu.be/CsR_yXzaAGw

Ok scratch the wire idea, I told you I was guessing.
it's the two tubes off the flow meter, going into the holes and then going onto the motherboard. I think that is where I'd start and chase that area.

Youtube can be a dangerous thing. I nearly took my kidney out, to see if there was a cyst on it. After watching a medical one.

As the blower/fan is working, my best guess is one of the flow sensor pipes has come off or they are the wrong way round.
These thin pipes are very easy to knock off, even on older models it is so easy to do.

Hi Hellosleep34,
WELCOME! to the forum.! Hopefully, you wil be able to get your machine working.
Good luck with CPAP therapy, hang in there for more responses to your post.

I can happily report issue has been resolved! I took off the case again and took out the motherboard and reset it carefully so the two clear tubes aligned with the sensors or flow sensor. I put everything back together and test it out and it started out at the minimum pressure normal. Thank you everyone so much for the insight to redo this and get it done.
