System One no longer heating hose
You might also try separating the humidifier from the cpap machine and shutting everything down leaving it off, then reassembling it all and trying again. Just to see if you can get everything to possibly reset.

The final error code also indicates a defective hose, but as you've tried multiple hoses with the same results I did not post that here. I am just posting it here so if anyone in the future has this issues they are aware of the three issues that could cause it.

#1- Using the 60W power supply instead of the 80W power supply.
#2- A defective power supply.
#3- A defective climate line.
If everyone thinks alike, then someone isn't thinking.
Everyone knows something, together we could know everything.

So I detached everything from each other and unplugged the power supply from the wall and left it all sitting for a half hour.

I plugged everything back in and got the same results, so I'm convinced something is defective. I'll call the supplier and see what they want to do next. Hopefully insurance will cover it.

I was having the same issue - but when I used an 80w power supply, all the locks disappeared.

I've gone into the clinical menu and the options are locked and can't be changed.

I thought maybe my tube was bad, but I just got a new one that I tried and it also doesn't work. So I've tried three tubes including a brand new one and the options remain locked.

Does this mean the unit is not detecting the hose is heatable and won't unlock the option? Or is there some super secret way of turning off the lock.

The "system lock" option is already turned off and I can change other clinician options like pressure.

Go to the CLINICIAN setup menu by turning the selector to SETUP,
then simultaneously hold down the control wheel and the Ramp buttons until the machine beeps.
One again rotate the selector wheel to SETUP and then press the selector wheel on the System One downward.

Scroll through the options until you get to TUBING TYPE and select UNLOCK - note if it is "LOCKED" the machine will NOT automatically recognize the Heated Tubing!!

Select the temperature desired for the heated tube, I selected "5". If the air is too warm you can reduce this. If you select "0" the HEATED TUBE WILL NOT HEAT UP!!

Be careful not to change the pressure settings for your device - ask your clinician for your correct setting if you are unsure.

Hope this helps. I got really annoyed by my heated tube suddenly no longer working, and purchased a replacement tube for $52 that I -did not- need. It didn't work either.

Your humidifier light should glow amber while the tube is plugged in and the machine is ON. (See attached photos).
