    Alex Duetto III discussion thread

    Gene Cafe Coffee Roaster $850 - Free Beans Free Freight
    Hello CS'ers

    Herewith some information on the Alex Duetto III. First Australian stocks are due late Oct/early Nov.

    Changes are as follows:

    • brew boiler decreases in size to 580ml
    • new case and cup tray
    • PID display will be red
    • a price increase

    Australian spec. will be configured identically to our current Alex Duetto II stocks.

    For CS'ers looking for a bargain, there are a few remaining with us and our interstate agents, so if you like the old, you'll get the bigger brew boiler and a hefty discount as well.

    We expect current stocks will sell out in the next week or two and then there will be some time while while we wait for the new ones to arrive.

    Chris

    What do you see as the pros and cons of the new machine Chris? All cosmetic? Also, the reduced brew boiler size? Is that so they can have the room to mount the pump horizontally not over the motor? Cheers!

    Hi CoffeeBloke,

    The hi-res graphics I have (not yet published) certainly look terrific. The PID display also changes from blue to red. The external finish is improved.

    At this stage, I have not seen the internals. While the change in brew boiler size to 585ml is no biggie (supplied via steam boiler HX), I am uncertain as to whether the aim is to provide a larger tank or to change the orientation of the pump and motor. It's no longer a biggie as a capillary tube is fitted to the motor. In the event of a pump leak, water drains away. FWIW, we see very few issues with the machine- so it's all about refinement.

    Cons- the inevitable price increase. Our buy price is up significantly.

    It will be easier for those who don't plumb in to access the tank as the standard cup handles will assist.

    Some more info attached in a .PDF for those interested.

    Do you have any photo's that are not distorted as much as those posted.
    ( even the PDF pics are compressed vertically ?)

    Hi Chris:

    Other than making sure your water is soft, how often are you recommending owners in AUS to descale? Do you agree with the instructions on the coffeetimeuk site?

    coffeetimeDOTwikidotDOTcom/izzo-alex-duetto-descaling


    What concentration of citric acid do you recommend?

    Thanks in advance,
    Mark

    Hi Mark,

    DO NOT descale if you can possibly avoid it. In dual boiler machines- it is a specialist job in dual boiler mahcines. Instead speak with Bombora supplies and purchase appropriate filtration.

    Recommended concentration of Citric is 0 PPM. It is NOT to be used in machines unless they are reduced to a boiler and pile of components by disassembling them into their pieces.

    Alex Duetto Upgraqded to 15A

    Thought i would report on the upgrade to my Alex Duetto to 15A -Dual Heater simultaneous operation Chris has swapped over my PID controller and the plug to 15A which allows Alex to start up with Brew & Steam boilers blazing. ( Normally supplied models are 10A so the PID gives priority to the Brew boiler)

    I wanted this for 2 reasons;
    1. faster startup.
    2. Steam boiler to maintain better steam pressure/temp during steaming [ after you start brew, heater will come on pretty quickly and hold out steam boiler]

    The change over PID is RED so if you really like your blue one don't do it!

    Results: 1.
    Startup :WOW it has gone from about 14 minutes down to 6m30s for both channels to be up to temp ( maybe not fully stable but Im not that fussy on temp so start making my coffee then)
    Restart: WOW. I now turn off the machine straight after I make a coffee because the restart is really quick. I do this more as a way of remebering to turn off the machine and not leave it on for exteneded time.

    2. Brewing. Yep both heater can fire up together here so steam temp stays higher during frothing. Overall a great result and worth the extra spend. And I'm starting to like the red display [ although Luke my son reckons its lame ;( ]. see the pic and decide for yourself.



    Regarding 15A upgrade my electrician has changed over the dual 10A plug for a single 15A. The wiring from the switchboard is 2.5mm cable and there is a 20A breaker on the board. The main issue is what else you have on that circuit- if it includes a kettle and toaster you're in trouble, but this was a separate circuit with only a frig and the grinders.

    Good stuff Brett,

    NB your post should be in the Alex Duetto II thread though as this thread is for the forthcoming Duetto III

    You must like cold, sour , coffee ! ...the group & PF cannot be much above 50 C after 6-7 mins. !

    hardly! I flush hot water through the group & PF before i remove the Pf and load up with coffee. Seems to do the trick.

    Anyway seems anything coming out of my machine is 100% on what i can get on the way to work.

    You're right Brett,

    No restrictors are are required- so full thermosyphon effect. As a result, the Duetto group comes up to temperature very rapidly and unless you have asbestos hands there is no way you can do more than quickly touch the group at 7 minutes. It's the first to be ready on our bench- by the proverbial country mile.

    It does actually feel like the machine has been transformed- learning to love it all over again!

    I was before setting the steam temp to 128 and it would maybe drop to ~114. but now it's set at 122 and doesnt drop below 120 for a double milk shot jug. So I am getting much better result and more consistent as well.


    I also picked up a triple basket and now our double coffees are as good as our singles.

    The newies have arrived and we have a demo on the bench.

    We are impressed with the new mirror finish (photos don't do it justice) and even better internal layout. The Duetto III is now easily a match for the finish of Rocket gear.

    Thanks Chris,
    They look great although I am extremely happy with my D2 ( 1 year old) and not about to change
    I wonder - Is there any chance that you can get access to the handles that are on the D3 so I could attach to mine? I have looked and haven't seen anything nearly as "stylie" as these!
    Cheers

    Hi Dave. Too early to know. We don't even have a parts schematic yet!

    Most who want handles on their V2 head off to the local Bunnings etc...

    hi Chris, does this model still have the same clearance between the group and the drip tray as the duetto 2?

    I have recently upgraded to an Alex Duetto III thanks to Chris @ Talk Coffee and his patient advice and assistance. I have to say I could not be happier. The design, engineering, finish and most importantly, performance of the Duetto is superb and has permanently ended my 'upgrade-itis'. Although most other machines in this price range would have probably been just as satisying to own, the Alex is a perfect fit for me. Thanks Chris!

    Thanks for the update mrsixties. I am delighted that you love your machine.

    Meanwhile- for those concerned with space between the group and the drip tray....

    Alex Duetto III discussion thread

    I just came back from seeing one in the flesh at Cosmorex. The height is still pretty low but ok for most use cases I would suspect, except mine: pouring directly into a 16oz takeaway cup for 95% of my coffees. The only time I don't do this is when I have visitors.

    I still prefer the look and finish of the Giottos but I am biased perhaps. :-)

    Hi Guys, I'm new around here but thought i should say a few words after my latest addition to the kitchen…Well after 4 months of intense research (its a mine field out there!), both here on CS and many other sites, multiple phone calls to people like Chris from Talk coffee, banging my head against the wall (figuratively) and more research, i finally settled on an Izzo Alex Duetto 3 and Mazzer Kony E grinder.


    This being my first proper espresso machine i have a lot to learn, currently i can produce drinkable shots but with this setup I'm going to be the weak link in the chain for quite a while, but then i love a good challenge!


    Being based in Perth, it was Chris who put me onto Dimattina Coffee, the Izzo dealer over here and they have been fantastic!
    A big thank you to Simon at Dimattina for supplying the gear and barista course and Chris from Talk Coffee for bench testing the machine and answering my many questions, i can't recommend these people highly enough, cheers guys.

    473 mls wow! Would that fit under any domestic machine?
    I use a naked p/f on my Alex II, everything that I use fits under it. Unscrewing the spouts off a regular p/f
    would also work.

    Fits under my Giotto Premium Plus and I suspect under most others (albeit with a bit of a tilt)

    I have heard that the Duetto III has a thicker than usual 8.5mm gasket in the group and that there are no naked portafilters that fit it. I would like to use a naked portafilter primarily if I bought the Duetto. What possible solution might there be to this problem?

    Not true. We are happily using a standard e-61 naked in our demo.

    also, 8.5mm is the default seal height for E61. It's only on rare occasions that an 8.0 or 9.0 is necessary.

    Does the Duetto III have an auto shut off for low water level in the reservoir when using tanked option or just a beep alarm?

    Yes- all machines (or at least all I am aware of) at HX/dual boiler level cut power to the element/s

    Hi every body- I am researching Alex Duetto 3 and after my research I wonder if anyone could help with two things I still don't get.
    A) why was the size of the brew boiler reduced - is this an economy/ space consideration or actually have some benefit to user?
    B) how does it run both boilers simultaneously in the Australian configuration (8 or 10 amp) when the previous model needed to be upgraded to 15 amp to do this. Will there be absolutely no need to upgrade amperage in new model? thanks heaps

    Hello espresstrain,

    The brew boiler was reduced in size as it aids recovery and shot stability.

    Australian spec is 2 x 1000W as per our webpage. The .pdf file there lists specifications.

    You're welcome to make contact if I can assist with more information.

    thanks TalkCoffee - I read the pdf. So both boilers manage heat simultaneously at 8 amp with the brew element wattage increased slightly and the steam element reduced slightly?

    How does the Alex Duetto 3.0 machine compare to Giotto Rocket Evoluzione V2.
    Obviously one is a DB and one a HX but from a practical perspective which is better suited for home use making all kinds of different coffees eg espresso, macchiato, latte, etc. I just want best value for money.
    Also thinking of Mini Mazzer auto for the grinder.

    Hello liv80 and welcome to CoffeeSnobs.

    My advice is that if it's possible, sample for yourself and come to your own conclusion based on your specific requirements.

    I don't know of anybody who has purchased both machines nor swapped from one to the other. As a result, any discussion would be opinions, rather than real world observations.

    You are most welcome to make contact if you'd like details of your nearest Alex Duetto dealer. Most sell both machines.

    If you are remote from a dealer, I am only too happy to offer you some pros and cons in a phone discussion. These may help you come to a decision.

    Hi all!

    I'm a newbie, but was introduced to high end espresso through a friend who has a ECM giotto (about 5 years old). Anyway, I'm keen to take the plunge (no pun intended)!!

    I have a specially wired 15A dedicated circuit to a special spot beside the kitchen sink, and I was hoping to be able to get the 15Amp(ed) Duetto III to be matched with a Macap M4 Stepless (chrome).

    I'm in Brisbane. Can someone help me out with where would be the best place to go?

    Thanks!

    Brett

    Hello Brett,

    Your closest outlet is site sponsor Coffee Roasters Australia- on the Gold Coast.

    FWIW, I think that unless you're proposing very heavy load on the machine, you will be fine with the native Australian configuration without an element upgrade. The bottom line is can you pull 2 shots, texture milk for them and have the mahcine ready to go again when you return with the next portafilter. The answer is yes. I suggest you sample Mark's demo machine and you can then make a call from there. I guess it's a little like purchasing a V8/V12 car when you spend most of your drive time stuck in ttaffic.

    We can supply 15A configuration as a special order from Melbourne.

    Cheers

    Chris

    Thanks Chris. Is it that I'm asking for an upgrade for the element, or just not the default downgrade? Did the duetto II come by default with the ability to switch and they have now taken that away?

    thanks,

    Yes Brett,

    As we have refined the Australian specification, we feel that the optimum specification is with our current configuration which is both elements simultaneous. The ability to switch is still available in the PID and performance is excellent as is.

    Hi,

    Can someone who owns an Alex Duetto III tell me what their steam boiler bar pressure drops to (approximately) whilst they are steaming milk? And how quickly in seconds (approximately) the temperature of

    the steam boiler takes to recover to full after steaming a small quantity of milk? I think I have a problem and need some info to analyze. I know I have asked this question already in another thread but want to

    hear from someone who actually owns a Duetto III.

    Thank you.

    How often does everyone take the shower screen out to clean it and the machine above? Does regular backflushing get enough of the coffee oil out of behind the screen or do you need to remove more regularly than annual servicing?

    Hi Coffeebloke,

    I personally back flush at the end of everyday just using water, at the end of every week I do a chemical back flush using about 1/4 teaspoon of espresso clean backwash detergent (more detergent causes a very stiff lever in the group)
    I also remove the shower screen at this time and wash, and wipe inside the group to get all the oil residue out.

    Ok thanks. I do exactly the same I've just never removed the shower screen and gasket for fear it will get loose over time. It is replaced annually of course but I will start removing it more regularly!

    Does anyone struggle to get a good whirlpool going in a 600ml jug? Can't seem to get good microfoam unless I steam less on a 400ml jug. Maybe a change of tips is in order? I'm using the 2 hole it came with.

    Assuming your machine is operating correctly it is much more likely your technique bloop. Remove the steam tip and check it's clear as well.

    Might be worth removing the steam tip as there could be small pieces of o-ring (orange colour) blocking one of the holes
    This has happened to a few duettos, including mine.
