Hi !

Please help. My Resmed s9 Auto select prompted me this morning "High Pressure Fault - consult your provider." Since you have a clinician's manual, can you please find out what that means? My cpap machine refuses to work any more.

Many thanks.

Narcoleptic,

I do not find any explanation or list of error codes in the clinician's manual. Following Mapnea's suggestion to pose your question in a thread of its own is a good idea and will probably produce more information

What does this mean? How to fix this? I can't find it in the troubleshooting manual. I hope there is a kind soul out there
willing to share his experience.

Thanks.

Hi, Narcoleptic,

I just googled "High Pressure Fault" ResMed S9 and came up with an answer for you - but I have no idea how to "copy" the answer. SO.. google what I just googled and the "answer" (I think) is on page 26.

Hope this helps - even if it is for a VPAP. Might give you some clue.

A high pressure fault is when the pressure sensor indicates a pressure in excess of 25 cm-H2O.
It could be a machine failure... like failure to close the loop on pressure control; which would indicate a need for service.

Or, a sneeze into the mask while running could over pressure the machine.

Gotta ask Zonk -- why did you go to temperature when the OP was for pressure?
Not a criticism, mate --- just curious.

Two things
1- This thread is a split thread, when I was posting in the other thread got a message saying something like 'this thread does not exist'.
I had to start all over again and the switch temp/pressure occurred

2- If something can go wrong, it will .... Murphy's Law

Anyway, the S9 user guide ink provided in post #6 , has your answer .. scroll down to "trouble shooting"
