error code 23

I'm not new to the cpap world, but new to this site. I have just returned from vacation and when I plugged my machine back in it registered a error #23 message. I have gone on at least 6-7 trips with this machine, through various airports, and the machine always worked when I plugged it in after the trip. I have an older model Respironics Model #1005961 REMstar pro with C-Flex. It has over 15000 hours, but it still seemed to working well. I hope someone can tell me what the error code #23 means and it is easily fixable, but I also realize it may be a serious problem. It's late for me and i'm going to bed with out the machine for the 1st time in years. HELP?????

No idear here. Here's the only reference I found online http://www.apria.com/manuals/Respironic ... 0users.pdf which basically says to call your friendly helpful DME.

Sorry I can't be of more help, but a backup machine would be good to have, especially since you've gotten so much mileage out of your current machine.

There were two generations of the REMstar Pro (before they introduced the Pro 2 in early 2005).
There was the first one and then the one with the serial numbers above 2 million

This one is for the oldest model:

23 - Boost voltage too high - The boost voltage exceeds a limit of 60v for more than 30 seconds - Replace main PCA

This one is for the one with the serial number above 2 million:

23 - Pressure offset - Check for leaks or kinked internal tubing - Replace main PCA
