Subject: Alex Duetto II mk3: Alarm Sensor
 

Hi Guys,

I'm using the internal tank in my Alex, but the Alarm Sensor does not seem to be working.  I have it turned on but when my water gets real low, to the point where I would think it would alert me, nothing happens.  

Does anyone else have the problem or a solution?

Thanks!

OK, I have not been inside your machine but if you give me (us) a little more info, I may be able to help anyway.

How is the low water system supposed to work? Is it a weight/pressure over a micro switch type system or is it sensor probes in the water tank and it detects water level by electricty?

Is your tank removeable? If you have the weight type system and the tank can be removed, what happens when you lift the tank off the bottom of it's well?

What indications are you going by for you to think that it should trigger the warning system? Look of the water level, dry tank?

The Duetto has a magnetic float that sits in a side channel, near the "switch".  When the float drops too low, the machine shuits off and the alarm beeps with a low frequency, low volume sound every second or two.  Sadly, I know this from experience.  I had vowed never to find out, personally, but I did this past weekend...shame on me.

To troubleshoot, make sure the float floats when there's water in the reservoir.  Now make sure your reservoir is installed correctly.  The float should be at the right side of the machine, when you're facing the front.  Make sure the water intake switch is set to reservoir. Make sure the switch to turn on the alarm beep mechanism is in the correct position (yeah, I know this is a no-brainer, but sometimes we forget to turn out brain on, so just double check it against the manual, please).

If it still doesn't work call your dealer.

Thanks for the recommendations guys.  I'll test it again tonight and let you know.  I know for a fact that there is no beeping when I pull the tank out.

The beeping might only be active when the magnet is near the sensor, rather than being a binary process (on or off), so pulling the tank out might have the same effect as filling the reservoir.

When my alarm activated, it shut off as soon as I started pouring in the water.

By no means am I disputing what happens with someone else's machine but my Duetto has weight based switch as many do. If you press down gently on the jug you can feel it click. I had mine stick in the up position so I am sure your's might be stuck in the down position. It's actually more like to be stuck down i would think. If you pop off the outer cover you can see it the switch I am talking about. I suppose it could be the alarm bypass switch if yours is equipped with one.  In fact prior to the little alarm bypass the recommendation from CC when switching from tank to plumbed was to put a handful of glass marbles in the tank for weight to shut the bloody thing up.

 
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.

Well, there you go!
So, it is a floating magnet system? Can you get a long pointie thing and push the float down? When it hits the bottom, the system should trigger.

ER, while I was typing the above, more answers came in, saying something different. SO, at this time, boys and girls, I am going to take a seat against the wall and watch before I dig a hole any deeper than I have already here LOL!

Same thing happened to me - make sure the reservoir is seated all the way down.  Mine looked like it was installed but wasn't seated properly placing the magnet too far from the sensor to trigger the alarm.  Jiggle the reservoir around and make sure it slips firmly down into the chassis.

Still haven't figured out the issue why it doesn't alert me.  

Going to call CC soon.  I'll let you all know what they say!
