gurgling sounds and water squirting out everywhere

I have had a ResMed 10 Autoset for nearly 6 months and use the DreamWear, under nose nasal mask. About a week ago I began getting a gurgling sound (too noisy to sleep) which seems to come through the connection at the top of my head. When I remove the mask water leaks everywhere, but then it will work correctly for awhile. The machine always says I have a good seal. I have tried changing the tube and have repeatedly checked all the connections. When this is occurring the machine also will not shut off like it should and the mask will continue leaking water. I finally have to unplug it to stop running.
My nose is very dry from the treatment and use to keep the setting on 8. Have now turned back to 6 because of the leaks......Any ideas? Very frustrated!

What you describe is called rain out in CPAP circles. It happens when your humidifier is set too high. The air cools as it passes along the tube, causing the evaporated water to condense in the tube. That's where all the water in your mask and tubing is coming from. There are a few approaches to fixing this. You can turn down your humidifier a step at a time until the rain out stops. You can use a heated tube to reduce the condensation. Wrapping your tube in a scarf to insulate it and tucking it under the covers with you to keep it warm can also help. Lastly, you can try placing the CPAP machine lower down so that the condensation drains back into the humidifier rather than toward the mask.

May be rain out as sleeptech noted but if you overfill the tank, you will get the same issue... I didn't pay any attention to the max fill early on and ended up with a face full of water...

That it true. I forgot to mention that. I have seen it happen.

Thanks...I do not overfill the tank , but things are better since I switched from humidity of 8 to 6. Will try the heated tube also.
