    No that's not normal, you should be seeing circa 9bar on extraction.


    Beauty of the Alex Duetto is that the pump pressure can be easily accessed and adjusted from the outside of the machine.


    Give Dimattina a quick call

    Thanks Anthony, I'll give them a shout.

    Not sure if it's just a stuck gauge or something because the extraction is fine but even with a blind in when I back flush the gauge just sits on zero.

      Just realised I never gave an update... Happy to say the machine fixed itself.

      We know the guys at Dimattina pretty well so sent them a video of the machine in operation and they confirmed it appeared to be a stuck gauge and the machine seemed to be operating fine so said I could keep using the machine and bring it in when I had time. About two days after that the gauge seemed to unstick itself, but the pressure was a little low (needle stopping around 7 bar)... another chat with the guys and they told me how to adjust the pump pressure. Great how simple it is to do on this machine. No need to fiddle around removing panels, there’s a convenient cut out on the side where you can put your screwdriver to adjust it.

      Now getting 9 bars of pressure and pouring great coffee. Also think I've got the hang of the steam pressure now and pouring latte art again... although not at the same level as the better half

      The machine has been a joy to use and really enjoying my coffee making again now and have even gone back to drinking more espressos.

        My Duetto III I used to own was ready to use in 7 minutes thanks to having no thermo siphon restrictors. Has this changed with the new model?

          I've seen a few of these and owned a current one one as well. Full steam boiler pressure in 7 min? Sure thing...

          Hot group and thermostability- they're really quick but no way. It's more like 15 minutes verified by Scace device. Best not to give peeps unrealistic expectations.

            An E61 group head up to temp in 7 minutes, unlikely.

            You are possibly referring to the boiler pressure

                The reason I sold my Duetto III was because the steam was too wet. Have they improved that on the IV?

                  Not been on the forums for a while so just seen this now. No issues with the steam here on my IV

                    I upgraded to a Duetto IV about a year and a half ago from a La Lavoni Professional and I have to say it is a really great machine that has treated me well during the lockdown here in Melbourne.

                    One thing I have struggled with though is getting good microfoam. It seems as though I have tried everything, however I still can't get close to what you would get at a cafe or I was able to produce with my La Pavoni. I worked at cafes for about 4 years throughout uni and was able to produce good microfoam back then, so I don't think it is to do with the Duetto having more power. I seem to get the best results if I use the two hole tip and block one hole, however it still isn't close to what you can get at a good cafe. Does any Duetto users have any advice on how to achieve better microfoam?

                      Hi Bob,

                      I dont have this machine any more as i upgraded to something different. However i clearly remember when i first got the machine i struggled the first few times and found going with a 3 hole tip was the better option for me. Its been a while since I had this machine and i look back at when i wrote the review so prove me wrong if i am but the steam tips with the least amount of holes are going to provide more pressure than those with 3-4 ( i forget what they go up to). The ones with 3 or 4 distribute the steam more evenly?

                      Cheer,

                      Chris

                        Thanks Chris, the 3 and 4 hole tips feel more powerful than the two hole with one hole blocked with the end of a toothpick. The milk based drinks I make normally do not have very much milk in them so I find this setup gives me the most time to stretch the milk etc.

                        I saw a post on home barista a while ago that the sproline knife single hole tip works well, however I can't bring myself to spend the $150+ on it. I guess I will just keep practicing and testing my technique for now.

                          Well after years of trying different espresso machines and being dissatisfied, I went back to Duetto and am pretty much back to making my favourite lattes. Wow, 7 years of disappointing espresso! The IV plus is an awesome machine. I can highly recommend it. Here are some pics.

                          Seriously slick, would love to see a writeup as to why you moved away from the DE+.
