There is no listing of what specific error codes mean, but it appears that it's a component failure. If any water got into the electrical parts of the machine, it could have shorted out, and if that's the case, you need that component replaced - no amount of button-pushing will solve the problem. There's really not much you can do, other than call your DME supplier who gave the machine to you. Trying to fix it yourself or opening up the CPAP housing might void the warranty.

ResMed's machines come with a 2 year warranty, and all repairs are supposed to be handled through their vendors (the DME) or home health care provider who set you up with the machine. If they give you trouble, call the ResMed customer service line at: 800-424-0737.

Wish I could provide more help, but this looks like a problem that only a ResMed repair facility can fix. Only other thing you might want to try is to disconnect the humidifier and hose from the machine, take all filters out, unplug it, and let the CPAP machine dry out completely (maybe in front of a fan) for several hours, then start it up and see if the problem persists. Mostly likely, this will not solve the issue, however, but it might be worth a try.

i got mine in sept 2009, so its been more than 2 years

Ouch, You may have to get another one from the provider though

I got an error on mine one day too, they came and picked it up and gave me another one.

*hugs*

Tora, contact ResMed. Do NOT mention anything about water or humidifier or anything like that. You'll shoot yourself in the foot by mistake and you'll regret it.

Another resource is Apria Healthcare. They are respiratory techs who sell DME equipment. They have locations throughout Indiana.

Funny how these things happen shortly after warranties expire, eh? :P But I agree with the others: Don't take it apart. You will void the warranty.
