cpap makes noice

my weinmann machine makes high noice sometimes at night and it disterb my partmer. it seems the machine "decided" to make high pressure for me, but forgot to calm it down when it was not nececery any more. what shall I do?

How old is the machine - you might be due for a new one. Have you taken it to the dealer to look at?

It's no clear whether this is a fairly new machine, or if it's an old machine that just started making noise.

Did anything in the environment change (especially the surface that the CPAP sits upon)?

If it's an older machine and nothing else changed, noise could be a sign that the machine needs to be replaced.

Please come back and answer some of our questions.
We would like to help, but there could be many causes.
