Thank you for your advice- where can you get a schematic of the resmed S9 and S8? is there a maintenance book available or a website that shows how to disassemble and repair these things?

I have a service manual for the S8 series VPAPs if that would be of any interest to you. I have not seen any service manuals for the S9 series ar later and I do not remember where I got this from.
Thanks for your advice- will plug the card in the computer and see what the
sleepyhead says. Still suspect a seal, maybe the seal on the humidifier lid.
A leaking seal would not cause the pressure to spike, unless it appeared to the machine as a breathing problem (i.e. it f sounded like snoring). I think you would notice something like that long before the pressure went up. A leaking seal would make the machine increase the flow to compensate, but it would not show a pressure increase.
reading the OP... You ran the S9 when the H5i tank had broken snaps?
The water level mark is near the top of the metal bottom.
If you did, my guess is water splashed back into the blower outlet where the pressure and flow sensors are located.
If so, the machine is running open loop.
And, the machine is toast.
Try this: Remove tank. Depress latch on back of machine; and separate S9 blower from H5i.
Hook up a plain 22mm hose to the blower and sleep one night without humidity.
If the pressure still runs up above the set pressure, the blower unit is fried.

millman, if you wind up getting to the point of having to decide between repairing or replacing your S9, this may be of some help. Early this year, my S9 Autoset went in to ResMed's repair facility in San Diego. When it came back, it appears that I had a new machine inside the old case. They had to replace the main PCB, the blower motor and chassis as well as provide a new power cord and 90 watt power adapter. With an hour's labor (they also cleaned out moisture and lots of dust inside), the bill came to $272, which was lower than I expected.
I had taken the broken machine to my DME, and they arranged the repair trip and shipping.
