Reservoir Stuck

Haha!

There is a little ridge on the inside of the "garage". Feel inside with your hand and you can find it.
You can see the matching ridge on the outside of the tank.
When the tank is pushed inside, there is an audible click, as the tank ridge slips past the interior ridge.

My guess? The retention clip that holds the silicone connection in place inside the machine gets loose and drops down behind the ridge at the end of the humidifier tube and locks it into place. Or something

The only "clip" inside is flat, plastic, and quite secure.
The interior ridges are at the outside edge of two small indentations just inside the "roof" of the "garage"
The matching parts are two sloping triangular bumps on the top of the tank.
The bumps fit into the hollows, but only if the tank seal is correctly positioned.
If the tank is not squishy when you squeeze it vertically, the seal inside the tank may be out of line.

I'm talking about the flanges on the reservoir getting snagged by a fallen or otherwise out of place clip. If the setup is the same as mine, it's the only thing I can see that would cause this

Since the catches are at the TOP, gravity would keep any small loose/broken parts away from there.
A foreign object, maybe?
Are you wiggling the tank forwards and backwards while pressing it together and pulling it away from the blower?
I always hold onto the blower with my left hand for leverage while removing the tank.
It is designed to hold firmly, but some folks may not have enough strength.
Are you a leftie?

I am an old hand CPAP user but new to this machine. I’m a big strong able bodied guy with good grip strength. The tub sticks on me on occasion (like 3 times in the 3 weeks I’ve had it). It requires near super human strength to finally remove it (without tools). I’ve read all the responses here and don’t think any of the well meaning responses are correct. IMHO I believe there is some sort of suction that is locking the tub in place. I could be wrong. Has anyone talked to Resmed? The reason I think this is that everything is assembled properly, the tabs barely lock/click in, the tub and heater plate are clean, the tub mates up with the inside tubes, etc. AND the problem is only intermittent. Like right after it happens one can easily insert and remove the tub after you get it out once. Really annoying tho because I otherwise really like the machine. I don’t think replacing the tub is the answer either. It would sure be nice if there were an easy workaround or fix, like cycle machine on or off or something. PS Not that this adds too much to my credibility but I’m a 35 year Arch/ Engr. This is an old thread but I gots believe that this isn’t a super rare problem. C’mon ResMed! Bizarre that they’d get everything else so right and have a “simple” glitch like this.

this thrad started 4 years ago and has been resurrected a couple times. is someone still having a problem today? If so, what is the exact machine we're talking about?

Brand new ResMed Autosense 10. If this topic has been floating around for this long has the problem and fix been determined? Nothing about in the User Msnual Triubleshootin section.

Maybe there is no problem, except for a foreign substance on the nightstand,
that sticks on the reservoir bottom, then fuses when heat is applied.
Someone mentioned this earlier in the thread.
Until you have to get aggressive about controlling blood sugar,
a late night snack seems harmless--unless crumbs become glue!
(Or you find out how dentists pay for their boats.)

I went up to my machine to fill it before bed so I don't wake my wife too much and really looked how it attaches to the unit. First the tab on the top is not a release, its just something to give you a bit of a grip. The springiness of the catch is the gasket that seals between the two halves and there are 2 tiny catches on top that barely grip the top of the machine.

I removed the reservoir and there is nothing inside that would catch on anything. Just two rubber gaskets that seal against the reservoir. The culprit has to be the metal plate on the bottom sticking to the metal plate inside the machine that transfers heat to the water. Its a very flat smooth contact point.

I think the best practice is to not pull out the reservoir and set it on the table as soon as you wake up but let it cool down first.

Oh and my dentist sees my worn down teeth from possibly bad orthodontia 40 years ago and sees a 40 footer.

For anyone who cares or is following this thread... I called ResMed. they were barely interested, claimed no knowledge of prob but took machine serial no and basically told me to address thru HME supplier. HME supplier has some exp with this being issue, as in hard to remove as a normal matter of course but not to degree of neatly not removable. They did however say they’d take it up with their ResMed rep and/or set me up with new machine of necessary. I’d rather not, but.... maybe the condition will abate with time/use. I am not naming this up tho! I’d rather not have this be a prob.

Just a reminder, most people can eat anything they like before bed.
Just do not set your tank down on top of the crumbs.
As we get older, we can experience sudden weakness.
See the doctor if you suspect this.
Such problems may be serious, but to let it go is dangerous.

After 2 months of use this stuck resiviour issue has abated. I am thinking that where the Stickage occurs is the bottom of the res to the heating element. When it stuck a few other times I just persistently wiggled the bottom and it came free and hasn’t been an issue since. Believe me tho I wasn’t just making this issue up!

I do believe you, Bob.
Older hard plastic can develop smoother edges.
Most silicone stays flexible, though.

I have had this machine for 3 months now and I have had this issue every night. I am a strong guy and I can't figure out how to get this thing out without a struggle every time. I've tried everything. What seems to work best is pressing down hard on the top and pushing it towards the back. But it takes time. And as someone else said, I hit the on button frequently when struggling with this.

As noted earlier there are 2 latches on the top of the tank that lock the humidifier into place. If you look at the side plate that replaces the humidifier you see the same latches. Pressing down on the button of the side plate releases the latches. Pressing down on the humidifier tank collapses the gasket and releases the latch.

If something foreign gets on the heating plate it can glue the humidifier to the plate making the tank difficult to remove. Keep this area clean. Every time you refill, clean the bottom of the tank and clean the heating plate.

Another possible cause is that there may be manufacturing tolerance issues with the tank itself. A possible solution is to purchase a new tank and see if it works better.

My unit has a snug fit but I can easily remove the tank one handed.
