Cpap machine Service Required

I have been using Respironics Remstar Pro
C Flex + for 7 years.
Last week my cpap machine started showing error messages Service Required and stopped working.
Does anybody know whether it can be fixed or not and also where it can be fixed/repaired

Thank you

Respironics used the term "Remstar" in several model lines since time began. So it doesn't really tell us much.
Back 7 years ago the newest was the PR System One model line but there's no guarantee you got the System One.
Even if you did...to be honest it's going to cost more to fix it than it's worth but you can call up these people and ask them approx how much. They will need to know the model number though.

Welcome to the forum. I have used acbio.com...good people there.

Probably, a seven your old machine should be replaced. The newer ones have the latest technology.

You should get an automatic (either a DreamStation Auto CPAP or a "ResMed AirSense™ 10 AutoSet™). In your case, probably the latter, as that's the brand you have now and you're happy with it.
