Reservoir ran dry during the night
I have the Resmed S9 Elite machine. The reservoir ran dry during the night. When I went to refill it, the bottom was so hot I could not touch it. The inside of the machine was very hot too.

Does anyone know if I damaged the machine? I did refill it when it cooled down, but I was afraid to turn the machine back on.

Thanks!!

Hi sj80125, Welcome to the forum!

There should be thermal protection in your machine to prevent meltdowns. I now say "should" because another member just reported a meltdown of his machine. . . although his was from a different manufacturer. I'd say give it a try tonight, with a full reservoir, and see what happens.

Statistics prove that people who have more birthdays live longer.

I've done that because I forgot to put water in.
No harm done in my case.

It should be alright, your machine is designed to work in these situations.(no one could afford meltdowns)
If you do not want the humidity just turn it off, one less thing to worry about until you need it.Okay
Nice feature to have in dry climates

The machines darn well better be designed to not self destruct when they run out of water, because it happens to everyone occasionally.

However, it is best to avoid it by making sure you fill the tank, or by turning the humidity level down if you can't make it through the night with a full tank of water. BTW, if you have an air leak, including leaking air out of your mouth, that will use more water. You need to fix air leaks if you have them.

The air tends to get stinky if you run out of water, but that's from cooking whatever crud is left in your water tank once you've evaporated all the water. Sort of like when you boil a pot dry on the stovetop. It's not (usually) the machine itself burning up.

If it's midnight and a DME tells you it's dark outside, go and check it yourself.

I would think that if a machine melted due to a dry humidity tank it would be the manufacturer's problem, not the patient's! I am sure the Consumer Product Safety Commission, among others, would get involved. Houses burning down due to melting xPAP machines is not a good thing.

RE: Reservoir ran dry during the night
It's not a real big deal; I've run the tank dry on several occasions due to failure to check the water level before going to bed. Your nose, nasal, and sinus passages will suffer more than the machine from lack of water! Oh-jeez

Hi sj80125,
WELCOME! to the forum.!
Your machine should be ok, just make sure you have plenty of water in your humidifier chamber tonight.
Much success to you with your CPAP therapy.

RE: Reservoir ran dry during the night
I agree with the "don't worrys." It happened to me when I stayed overnight in someone else's home with very low humidity. The reservoir ran dry and in the morning I noticed the mask was warm and the reservoir, very warm. I asked ResMed about it and they said that there is thermal protection that will prevent damage to the unit. In any event, it has been working fine ever since.
