Res med S9 issues

[Ian Canada]

Hey guys, i have the resmed S9 and I'm having a problem

the machine was working fine until a few nights ago. When It starts you get the initial build up of pressure then it calms down to normal flow. But it keeps cutting in and out with initial pressure. Almost like the cpap is breathing on me sorta. this will either just continue( stop and start) or the machine will stop the flow all together. this makes it too annoying to use.

anyone encounter this before? any help would be amazing

Can you tell us what model machine it is--Elite, Autoset, or whatever? S9 is a SERIES with many models.
Also what are your settings, how old is the machine, and has anything unusual happened lately?

Did you change hose size? Do you have the correct hose size selected in the machine menu?

How old is it? Still under warranty? Maybe you need to take it to the supplier for checking?

I have the exact same issue. I couldn't even figure out how to state what it was doing. And it's only occasionally. I've changed nothing about my set up or system. I'd really like to know what causes this too.
