S9 H5i not heating Please Help!

[oscar98]

I did a search and read previous threads about this problem and any solutions found there have not seemed to make a difference.

I used it on the first night and woke a couple times with a very dry nose and throat. I just assumed I must have been mouth breathing and went back to sleep.

On night two I was having trouble falling asleep and noticed the air felt cold and dry even though I had the humidity set to 3.5. I felt the water and the heating plate and both were ice cold. I turned the pre warm cycle on and it warmed the water. I started the cpap and woke a couple hours later bone dry again with cold dry air. Felt the water and plate and again ice cold.

No matter what humidity I have it on it will not warm up. Is it broke? Or, is this a symptom of the climate control thingy that senses the temperature and humidity in the room? I tried changing the climate control from auto to manual and that didn't help.

I'm using the regular slimline tubing that came with it.

Any ideas???

thanks

Dear Oscar,

When you went to the little icon with the drop of water, did you hold down the circular button for 3-4 seconds so that it would start warming? If you did, did it say "warming"? Ours does - using a slimline for now also.

Yep, did that and it did warm. But once I started the therapy it stopped warming and got cold again. The only time it warms is when I manually start the warming mode. Once it has finished the initial warm-up then it doesn't get warm again at all and I wake up all dried out with the inside of my nose burning.

On the first night I filled it to the lowest line and even on 3.5 it has used a very small amount of water after 2 nights. It seems to only be working like a passover humidifier and instead of heated.

does the orange light come on when you are prewarming it? I seem to remember reading somewhere that it wouldn't heat the water under certain conditions IE room already having enough relative humidity. Although i'm not sure on that one. I highly recomend getting the climate line tubing though as it actualy heats the air as it goes down the tube so when it gets to your mask its nice and warm. I have mine set at 80 degrees and it is wonderfull.

The orange light does come on, but it also comes on when I turn the machine on without pre-warming. Even though it comes on when I don't turn on the warming I positive it is not heating unless I tell it to warm. I was wondering what the difference between blue and orange lighting was.

I think I will go pick a climate hose up on Monday, but in the meantime I'm wondering if I should ask the DME to exchange my humidifier. I've read everything I can find about it and so far nothing has seemed to explain whats going on.

thanks for the replies

If your DME will replace the humidifier I would say go for it. I will say that before I got my climate line tubing the air did feel very cold coming out but I could feel the humidity also. The air did not feel warm at all though before the climate line tubing.

I just switched to this DME and they have been really good so far. They even went as far as to offer to replace a mask the my husband recently got from the old DME. I think they would replace it without a problem. I don't so much mind the cold air but the lack of humidity is a problem.

I just went in and messed with it some and notice something. When I turn it on without warming the orange light came on. I took the tank out and turned in on with the lid open so I could feel to see if the plate warmed up and it did but of coarse the machine got mad at me for having the lid open and shut off with a lid open warning.

Next I turned it on with tank in and lid shut and I had my hand on the bottom of the machine to feel for warmth. Right about the time all the lights go out I could feel it starting to warm but as soon as the light went out it immediately stopped warming and cool right off. I shut it off and felt the plate and it was not warm at all.

So it appears that as long as the orange light it on it is warming. Light goes out and no more warmth.

My orange light doesn't come on after it finishes warming but the air also never felt warm. I think it only heats it enough to produce the right amount of humidity and thats it. Of course I don't really know of a good way to test if it is putting out the right humidity or not short of getting a device that tells you the humity that is in the air and maybe putting the mask over it to see what it reads. Not sure if that will work or not though.

I really can't say for sure. I don't know if what I'm noticing is a difference in how this humidifier functions or if its and actual problem. With my s8 escape if I had the humidity on 3 the air was not warm but I could feel the moisture in the air. With this one I've had it at 3.5 and the air feels bone dry.
I'll try cranking it up to 5 or 6 tonight and see what happens.

We have discussed this before:

Yes, turn up the humidity setting and test it out.

My setting is 4 now, and seem to work fine. Every night used about 1 level of water.

Yep that was the thread I found in the middle of the night when I had a problem. I had tried everything in there and still wasn't getting any humidity. I had gone up as high as 5 and still nothing.

Last night I cranked it up to 6 and did get humidity. It didn't feel like much at first and I'm sure getting a climate hose will help with that. After about 3 hours I had a bit of rainout and dialed it back to 4.5 for the rest of the night.

I wouldn't even have noticed the rainout except for that my hand was near the vent and when I exhaled it was spraying my hand with cold water.

It was just a bit humid here the first 2 nights and perhaps the humidity in my room is what cause the lack of humidity in the cpap. I'm not sure I like that option. If I tell it I was humidity of 4 then that's what I want, not what it thinks I need based of room humidity. Last night it was much drier and the humidity was obviously working.

It looks like I just need to get used to how this machine works differently the the last one.

Thanks for all the help and suggestions.

I believe the heating is for regular the amount of humidity only, not provide warm air - that is the job for the heating hose.

Correct, but the problem was that I had none of either (warm air or humidity). All I had was cold dry air with my humidifier up as high as 4.

With my escape on a setting of 2.5 I cold feel the moisture in the air which had the sensation of being warmer although it may not have actually been. With the S9 it works differently and takes some adjusting to.

Judging from the number of posts about this issue it seems several were unsure if there humidifiers worked or not. I'm still not convinced it is working correctly but will keep testing it out and ask my RT tomorrow as well as pick up one of those nifty heated hoses.
