This is a good machine and has been used regularly since sept 2018. My issue is that I sometimes wake up with the mask blowing so hard it goes past the sealing rings. It clearly ramps up the pressure but doesn’t seem to return back to an easy pressure. I end up having to switch it off and back on again.
1) Is the machine likely to be faulty? Anyone else had this issue?
2) when do these need replacing in terms of years?
3) Also if I replace with a variable pressure machine which make would you recommend?
Apologies for all the questions but I have had terrible nights sleep with this issue.
