Izzo Alex Duetto II discussion thread

[Ausnadian]

Just had a revelation, <face palm>, I put my finger over the low water sensor to cover it completely with the tank out of the way, and no alarm went off, so I guess I have a dead sensor!

[Ausnadian]

I am having issues with the low water alarm, I take it that it is a light sensor that when covered by the little white level marker sets off the alarm. I just recently did maintenance on the machine and removed the water tank to clean, since putting it back in the low water alarm isn't working (I know the switch at the front and have never touched it to make the alarm sound) and then it has issues sucking water into the boilers, which letting them cool a bit seems to resolve.
Does this makes sense, I have tried a number of things like pulling out the water level marker and putting it back in, but so far to no avail. Any one else had issues like this they could fix?

Thanks for the info. Much appreciated.

20g perfect in the duetto.

[CoffeeBloke]

Sure do! Within 18 to 22 is fine in the cup but I find with my duetto the bigger doses flow more consistently to time and the puck is dry on completion. I normally use the 20g either for two medium strength small lattes or a short macchiato pulled as ristreto and it is brilliant. Like the rest of the VST threads on this site, I do agree that they're very sensitive to technique but the flavour is better than the stock duetto baskets in my humble opinion and when used with a fitted tamper, they're easy and consistent. I also find my 20g VST easier to use than my 14g if that helps.

[Pete39]

Thanks CB. That's the answer I was getting from the measurements I could find, but it was pretty close!!

Do you use the 20g? What dose do you find is good?

Pete

[CoffeeBloke]

The 20g just fits

[Pete39]

Thanks Chris - I remember that you are VST free and I haven't fully decided to get one yet. Am keeping your EP HQ baskets in mind, just exploring the possibilities. Borrowed an 18g VST from a local cafe here not long after I got the Duetto and got lots of nice pours, but nothing amazing flavor-wise. The wheels continue to turn ...

Hi Pete,

We're a VST free zone so I can't be 100% certain. That's said, none of our other triples fit, so I'd doubt it.

Cheers

Hi All,

Do the 22g VST baskets fit in the standard duetto ii spouted pf?

Thanks,

Pete

Hello bb, the response was fro specialpants.

It could be wear to the group pistons or to the cam. Once lubricated (food safe high temp grease), lubrication should not be required for quite some time.

When backflushing- 1/3-1/4 teaspoon of chemical only.

hi guys, thanks for the response. Yes when i took it in i mention the problem and he did a good lube job and said it's all fine, after taking it home i did a few shots the problem reappeared and i have since contacted CRA again and i need to take it in to get it throughly checked out. But in the mean time i just wanted to see if anyone here has seen or heard of the problem before and maybe have a answear??? Chris was this meant for me

(Group service including cam lube and a check of the cam followers on the group pistons is also a routine part of a typical service and one we always do.)

[Pete39]

Hi BigBully,

Surprising it came back with the problem still there. Just wondering, did you mention it when you tool it in? Have you contacted CRA again?

At 2 or 3 years dependent on use, the expansion valve may well be deteriorating. It's in the heat side of the machine, so it's definitely worth a look.
