Airsense Autoset error, blockage in tube

[Possum]

My machine has been regularly stopping in the middle of the night, and an error message flashes on the screen saying that the tube is blocked. I check the tube and nothing seems to be wrong with it. There aren't any kinks that I can see, usually not even any significant moisture buildup / rainout.

Has anyone had this type of issue before or have any ideas about what could cause it? As usual my supplier is mostly useless when it comes to troubleshooting.

Pull the tank and check inside to see if there are any obstructions with any of the outlets. Circled in #5 in pic.



Check the diffuser vents in your mask for blockage and when you run the machine with your mask on that you have venting. If all that looks good, it could be an problem with the internal pressure sensor.

I would also check your inlet filter on the left side of the machine. Chances are if that was blocked you would get flow sensor error and not a pressure sensor error but worth a look.

Wow, great tips! Everything checks out, but sometimes I get a lot of condensation in my P10 nasal pillow mask and the diffusers get wet. Sometimes it's so bad that I wake up because I can't breathe well enough, but I've still never gotten this error. Do you think that could be part of the problem?

Possibly, if the vents in the mask are getting clogged. What are you running your humidity setting at? Also, probably not the problem but make sure you don't fill the tank up too high.

Should fill to the green line, not the red line.



If you use less than half the tank in one night, you can fill to the yellow line and still be okay.

I have been keeping humidity at 5, hose temp at 84. The temperature of my bedroom is in the 60s. As I said, I've had issues with rainout before but never got this error.

Try another tube, to rule out the fault is with the tube
If you get the same message, more likely the machine is faulty and need to be replaced under the new machine 2 years warranty

Thanks for the link, but I've actually alreadly seen that thread, and it is regarding a different issue. I'm pretty careful about reviewing current threads before posting a new one..

When they first came out this error message came up with a lot of machines, first they though it was faulty tubing, but it ended up being a software issue Resmed pushed out a software upgrade through the modems.

I was getting the blocked tube message as well when condensation occurred in the mask line. That's why I referred you to that link.So, I do think its either a faulty climate hose or rain-out\condensation in the mask tubing. If you follow the tips on getting rid of rainout\condensation and you don't solve the problem then you have eliminated that as the issue and I would return the machine for a new one. Good luck.
