Disconnect from electricity source, then re-connect.

Sleepster offered a good solution and sometimes completely un-plugging and re-starting the machine will help... however if it doesn't help, look at zonk's solution.

Go to the link zonk suggested-- take a look at that full thread (here) and you see further down instructions for taking apart an old REMstar like the one you have.

Most likely is that one of the small rubber hoses (seen in the picture below) has either come loose or grown brittle and has cracked with age, creating a small leak, which will cause this error message.

The solution is either to re-attach the rubber hose, or if it's bad, somehow find a rubber hose of the same internal diameter and replace the bad one. Have no clue where you might find a small length of that type of hose local to you, but I've gotten similar hosing via a local hardware store in my city (Ace Hardware). If it's cracked just on one end, you might have enough length already there to cut a few millimetres off one end and re-attach it so that the cracked end is no longer used.

Here's a pic where you can clearly see the small sensor hoses:



NOTE: If you replace or fix the hose, afterwards you may need to re-set the circuit board so it doesn't continuously give the error message. In some cases this is as simple as resetting via a jumper on the motherboard. Although a CPAP motherboard is not exactly like a personal computer motherboard, the concepts of re-setting the CMOS chip are similar. You can either take the small watch-style battery out for 24 hours and then put it back it, or do it quickly by using the board's CMOS-reset jumper pins. A video on how to do that here:

Hope this helps, let us know how it goes!

newbie here, with a simple question:
my BiPAP machine (Respitronics Pro2 Domestic) recently showed 2 error codes. one was error 25, the other error 47. my husband found this forum and took the machine apart, and the hoses were in good shape, but had water in them. he cleaned the water out, and put it back together. im still getting the error codes, but i was able to get the machine to turn on. he is talking about resetting the CMOS, but were both worried about loosing the settings!
my question is, will resetting the CMOS loose the settings? my machine has a card that needs to be inserted , but im not exactly sure what its for? does it have my settings??? can he reset the CMOS and insert the card, and were as good as new???

thanx for your help!

No idea! It may reset the error codes and clear them from the system. If you have the clinician's manual, you can easily set the pressure bit yourself.

The error codes are here:

Or you can get a new machine. Supplier #2 has open box and gently used machines.

Just to add a bit to Paula's info, resetting the CMOS will not harm anything - it will only clear out any settings (and most likely any error codes), restoring your machine to factory default settings. You'll simply have to put your pressure and other settings back into the machine. You can get a copy of the Clinician Setup Manual HERE via email request, which will show you how to set up the machine. You'll need to know what your pressures should be.

The card is for the ability to read the data remotely. You don't need it in the machine at all unless you're attempting to read data. Also, it's possible that the error codes are recorded on the card, so re-setting CMOS would not clear those out if you put the card back in and the errors have been recorded on the card.

EDIT: also, I'd look into getting a newer machine, as Paula suggested. There have been a TON of improvements since your machine came out, both in comfort and effectiveness of therapy. A CPAP machine has an expected lifespan of approximately 5 years max.

[Sleepster]

Sometimes the doctor or DME will put the pressure settings on the data card. If that's case, inserting the card will cause the machine pressure to be set at whatever is loaded on that card.

I think that you can just go ahead and set the pressure to whatever you want after that. Not sure, though.

Hi kayjaz, WELCOME! to the forum,! and I hope you are able to get your problems straightened out.
