Sleeplay doesn't honor warranty

I ordered the ResMed Airsense 10 a few months ago from Sleeplay and the water chamber has started to rust. I called Sleeplay to get a replacement and they denied it. I then called ResMed and they said they couldn't do anything about it. I use distilled water and dry it after every use.

I was beside myself. I'm very well aware that Customer service has gone down over the years but I find this to be ridiculous. Anyone else have this problem?

By the way this was replacement for a ResMed airsense 10 I bought 8 years ago. During that time the water chamber never rusted. Being that it is the exact same device, I did notice that they did cut corners in the build quality of the water chamber.

I have a ResMed AirCurve 10 and have been using it for a couple of years now. The water reservoir for the AirSense 10 and for the AirCurve 10 are exactly the same. It's impossible for your tank to rust as there are ZERO parts made using ferrous (iron) materials. No iron no rust.

The metal used in the tank is either stainless steel or aluminum. Don't believe me? See if a magnet will stick to the bottom of the tank. If there isn't any iron present, the magnet will not stick.

Conrad, I think you've got your chemistry wrong. Stainless steel (like all steel) is primarily iron. In addition, it contains carbon, chromium, nickel and traces of other additives. It definitely contains iron. (Note - Some few stainless steels have their iron in the form of austenite, which is a non-magnetic form of iron). My S9 VPAP Adapt had a tiny pinhole in the stainless and that developed a tiny bit of rust (almost microscopic). I've checked my AC10 ASV, and a magnet doesn't stick. My old S9 is in the back of the cupboard, so I won't go pulling that out.

In addition, the AS10 and AS11 have very different water chambers: they are not the same.

To the OP - how bad is the rust? A pinhole or two won't hurt anything. If you have insurance cover, you might be better going through your insurance company.

" I think you've got your chemistry wrong. Stainless steel (like all steel) is primarily iron."

Nope, I don't have my chemistry wrong, you do. You may want to do a bit of research on this before speaking up.

High grade stainless steel has ZERO iron content and is nonmagnetic. Some types of stainless are ferromagnetic and do contain iron.

"Austenitic stainless steels are generally non-magnetic, while ferritic and martensitic stainless steels are magnetic."

Gilpv22,

Any chance that that water chamber is not a genuine Resmed chamber? Does it have the Resmed logo on it? There are a bunch of non-Resmed AS10 water chambers that can be found on Amazon and my own DME unless I specify, has at times tried to substitute non-branded supplies to maximize their profit. This likely may not be the case, but worth asking.

Have you ever washed the chamber with tap water? My well supplied tap water contains minerals and iron which has at times left a discoloration on the metal of the chamber which could look like rust.

I assume the 'rust' is inside the chamber and not the outside(?)

If the 'rust' is minimal, can it be cleaned off and see if it returns? Tooth paste on a brush may work adequately and leave the chamber 'minty' fresh.

Any chance of posting a picture of the the 'rust'?

How many months? The warranty is 90 days.

Of course SS has iron. Might be in the form of ferrite, but you can't make ferrite without...

You also need to do some reading on this subject.

Not all types of stainless steel contain iron/ferrite and are magnetic! Got any stainless-steel screws in your house? Check them with a magnet.

Austenitic stainless steel is one of the five families of stainless steel (along with ferritic, martensitic, duplex and precipitation hardened). Its primary crystalline structure is austenite (face-centered cubic). Such steels are not hardenable by heat treatment and are essentially non-magnetic. This structure is achieved by adding enough austenite-stabilizing elements such as nickel, manganese and nitrogen. The Incoloy family of alloys belong to the category of super austenitic stainless steels.

This is all beside the point. A magnet will not stick to the bottom of the water reservoir; therefore this part is NOT made with an iron containing metal, period. So, the metal can't be rusting and if rust is present, it's coming from something other than the metal base.

The only thing I was wrong about was thinking you would have figured out what you're talking about by now.

No no no no no no no no no no no no no no no

Keep reading this till you understand it:

https://getmetals.com/blog/is-stainless ... n-magnetic

All stainless steel contains iron, which should theoretically make them magnetic. However, not all stainless steel has a ferritic or martensitic crystal structure. Some have an austenite structure, which makes them non-magnetic.

I can't let this one slip by (my original degree was in Materials Engineering - a Doctorate in Nuclear Materials from MIT)... Stainless Steel ALWAYS has Iron - that is what the "Steel" part of the name refers to. Whether it is magnetic or not - or whether it "rusts" or not depends upon a lot of other factors. The Wikipedia entry on Stainless Steel ( https://en.wikipedia.org/wiki/Stainless_steel ) starts with "Stainless steel, also known as inox, corrosion-resistant steel (CRES), or rustless steel, is an iron-based alloy..."

While Wikipedia is not an academic reference - my personal goto for all things Metallic is the 1948 Edition of the Metals Handbook (published by the American Society for Metals) - the 40 page chapter on Stainless Steel will tell you everything you need to know about it. Of course, there are more recent editions, but I have a personal affinity to this one.

This portion of the discussion is, IMHO, a red herring.

Thanks but all the heavy lifting has been done already.

Ok then, I'm wrong.

All stainless steels contain iron, but not all stainless steels are magnetic. Happy now?

The bottom of the water tank is either non-magnetic stainless or aluminum. Either way, it's not rusting.

Wrong again, but I'll let Mr. Metallurgy handle that one.

I believe that would be Dr. Metallurgy to you.

How am I wrong this time?


Apologies to Gilpv22 for the thread-jack.

Yeah, I know, that was meant to piss you off. Dr. Spock is just collateral damage.

For my next trick, I'm gonna make you roll over.

That was my eyes rolling.

My trick will be to make you disappear, from my view anyways...

Watch this.
