DS560 "clicking"

[stephen N]

Gidday all,

My 14ish month old DS560 has started to make a soft "click" every time I inhale or exhale.

I am guessing there may be some type of non-return valve in the machine that is either coming loose, worn, or needs adjustment.

Any idea if this fault can be a DIY fix?
Are parts available if needed?

I have emailed the company I purchased the machine from, and expect a reply pretty soon [they have been excellent in all dealings]
I just figured it couldn't hurt to check with the crew here too

Thanks,

stephen

There are no DIY fixes to a machine unless it is hopelessly out of warranty. I've never heard the click, but the machine changes flow and pressure rapidly during the transition from inhale to exhale. I'd wait to see what the DME is going to do.

Same soft "click" every time I inhaled / exhaled last night,

Tried another hose and mask - no difference.

Machine has 2947 hours, and was purchased from the USA, so warranty probably will not be recognised by local distributors.

I will wait for the USA supplier to reply before I open my machine and start tinkering.

I need to show a bit of restraint and watch myself - Tim Taylor has nothing on me.
With my history, if I "fix it" it will end up looking like it has been crossed with a 6-71, and be capable of inflating the Hindenberg in seconds

and.........I'll be sleeping in the shed.......again

You might send a PM to member "accurate". Ian is head of Supplier #27, an authorized repair facility.

Thanks Sleeprider - I sent accurate Ian an email, and look forward to his reply.

I have not received a response from the USA supplier I purchased the machine from.

Over the last few nights I have -
- tried the machine with different hoses and masks - no difference.

- tried without the humidifier - no difference.

So, this afternoon, to keep the Wife happy I delved into it's innards and messed about a bit more,

- stripped the machine [very carefully], could not find anything obvious, put it back together [no leftover bits for once!]

It usually takes a few minutes for the click to start - so we will see how it goes tonight!

I kinda like to tinker myself, so It's good to take a look to eliminate anything loose or obvious. I'm always pleased when there are no leftover parts as well. Good cause for the banana celebration! :LOL: Hopefully you'll get some answers soon, although Ian is probably off for the weekend. I'm just at a loss as to what the click could be.

I'm guessing that there aren't many cheap backup used machines that come available in Au.

[stephen N]

You are right - no such thing as "cheap" machines around in Australia.

Second hand high hours machines listed for sale on "Gumtree" [similar to your craigslist] are usually well over what we would pay for a new machine from the USA.

Last night the Sandwichmaker didn't hear the click - but she reckons there is a high pitched squeal every so often.

I didn't hear it - I was sound asleep at the time,
but I wonder if the impeller of the air pump might have excessive end float.
Maybe the clicking was from the impeller sliding backwards and forwards due to changing back pressure when I breathe?

My opening it up and putting it back together may have altered any play in the shaft - stopping the click, but resulting in the squeal every so often?

Not knowing the finer details of the motor and impeller design make it difficult to figure out - and I don't want to do a complete tear down to find out!

Since I opened up my machine [and put it back together] it has been behaving!
Apart from the first night where my wife was hearing an intermittent squeal or squeak, there has been no funny noises to report.

Still - I will be paying attention to anything that might occur in the future, and my wife will be quick to poke me in the ribs too.

no reply from the original supplier or accurate ian - but no problem for now.
---------------------------------------------
anyone know what is inside the gizmo that resides in the back of the humidifier [connects the output of the air pump to the humidifier tank]

Wondering if there might be a loose baffle or something inside it that could shake loose or jam in place every so often

thanks all

You may want to check the 2 seals on the humidifier box. One between humidifier and the hose. And the other between humidifier and machine (it's the baffle like thing at the back wall of the humidifier body.

These are fairly cheap to replace. Supplier #1 carries them.
