I was looking at CCS's Duetto II page on their site, and they do advertise, ""NEW" alarm switch", which explains the different responses here (weight based v magnetic float).  You'll have to check which one you have.  I can tell you, I got mine in December 2011, so if you got your since then, you'll have the magnetic float, like me.  If you got it before that, Chris' may need the production date from the machine to help you.

It'll be interesting to hear what they have to say.

Good luck!

Issue resolved.  Apparently the magnet sensor was stuck on the plastic piece within the tank.  I should have noticed this but I guess I over looked it.  Easy fix, I just unstuck magnet floating piece with my finger...feeling pretty dumb right now :-P

Thanks for all the help guys!

glad to see you got it fixed so easily!  This knowledge will probably come in handy in the future, when someone else has the same problem.

No doubt but it's a little scary that you could run your machine dry i would keep a really good eye on it

 
Yes i have a reason for leaving SCG off my list, yes it is my opinion, yes it is subjective as opinions are by definition, no don't start a flame war because you disagree.

I have a mkIII and the low water sensor isn't working :-(  I have pulled out the water tank and cleaned it thoroughly, and even removed the magnet from the tank and manually placed it over the sensor, but no alarm :-(  It did work previously and I'm just not sure why it doesn't now!  Machine is about 3 months old...

Thanks in advance if anyone has any advice!

So I figured it out.  When I started using my machine, I saw a rust mark starting to develop on the magnetic float in the water tank.  I realised that it was actually some sort of metal filing which had become attached to the magnetic float and it was rusting.  So I pulled the float out and cleaned it up.  When I reassembled it, I didn't realise that the float has a specific orientation which must be preserved.  For my machine (and likely all of the MkIIIs), the orientation of the magnet in the float needs to be facing out and at the top.  Once I changed this, then the sensor started to work again...

A beautiful machine!!  I love it.  Teamed with a Macap M4 stepless grinder :-)
