I have no idea.

The main reason for me to buy the bottomless (aside from the fact that it looks delicious) was because it’s hard to clean the original one. It gets very sticky under the basket and rinsing doesn’t change it. This is super clean I love it.

One thing at the time gents. :-)

Let’s worry about the real issues (locking the PF, leaking) and then we can worry about the subjective issues (cone extraction, etc…)

Remember, if it tastes good, then you are winning.

    LOL You’re right. I mean it’s not bad because I drink with milk but how much of the taste is due to poor grind I cannot tell. I will clean it up and have another go first and see what happens. I will report back

      erkal I drink exclusively latte too but I usually try to taste the espresso before adding milk. just to see if I get it right (and in most cases a chaotic extraction as can be seen by the bottomless pf does not taste right)

        delta76 do you find that low acidity and medium to dark roasts are better for milk?

          erkal to my taste, yes, mostly yes. People drink light roast for the unique flavor so it’s a bit pointless IMO to make latte with it, as milk masks a lot of notes. I usually don’t drink dark roast (medium dark is ok). of everything I tried (not a lot, and I don’t have great taste bud neither), I prefer the unique taste from ethiopian yirgacheffe roasted to medium. I recall that Ethiopian coffee in general has unique taste due to high sulfur content in the soil.

          but don’t be afraid to try out new things. only you can decide what you like best. :)

          Hello!

          So I got the Allen key, un screwed it, gave everything a proper clean, brass water dispenser, red ring, black gasket, everything is brand spanking clean. It was pretty disgusting actually. I then did a backflush with the cleaning product saches that came with the machine. I then screwed everything back on without tightening too much. I then went on to making a shot. The beans from the previous video were finished I had some Mexican and 19g of this one was way too little compared to the Indian from the last video which was almost overflowing. So I tried with 20g and unfortunately again there was some dripping, although very very minimal, I heard the *psssst as soon as the pump began following the preinfuse. Only a few drops seeped out, not even enough to see any drops fall but they were out on a closer inspection. I can upload the video but you cannot see it in there.

          So now its either puck being too full or maybe I might have screwed too tight again? I can see the shower screen screw has left a mark on the puck so maybe it is too much. I will try again with less coffee, I really hope thats the issue.

          Edit: I have loosened the screw a little more, just enough to stop the screen from turning when I push.



          You need to do that coin test as described a few posts above.

          Also, I can see coffee around the rim of your basket. You need to make sure things are clean - both the gasket and the basket lips, otherwise it won’t have a proper seal.

          Also, did you manage to remove the group gasket and gave the whole group and gasket a clean? And, is the gasket the right way up? (flat side facing down).

            MediumRoastSteam Yeah I noticed the coffee around the rim as well, I have no idea why thats there, it was almost new clean, I took it all out including asket and red ring and washed/brushed all parts with washing up liquid and wiped the inside with brush and cloth, then backflushed. There was nothing there. You can see the rim of the puck is also clean when I prepared it. I have no idea how that got there.

            Could you take a picture (hopefully with good definition and light) of the bottom of your group, without the portafilter in place? Thanks.

              My housemate just pulled a shot as well so its less clean now, but only 2 shots since cleaning it completely.

              try grind a bit finer, but with less coffee (interestingly if your grinder is time-dosed, then it will grind less if you go finer)

              you can also try to puck screen. I have a stainless steel puck screen and then now I am using paper filter (~10 eur for 400-500 pieces) . don’t want to go back, I don’t care about the improved extraction (actually if i have one at the bottom, I can grind finer so I assume it’s true), but the pf is so much easier to clean, and the shower screen is virtually clean after each shot.

                delta76 My grinder is not ideal unfortunately. It’s a Baratza Encore with Virtuoso burrs. I use scales to grind single doses. I will do another shot now with 18g, finer grind and try the nickel test as well.

                  erkal - is the gasket the right way up? - if it is (flat side, not bevelled) facing down, than the only thing I’d suggest is that your gasket has been worn out prematurely, or is damaged. Saying that, you said it doesn’t happen with the spouted portafilter, correct? - which then rules out the gasket theory, and the only possible explanation is that there must be something wrong with your portafilter, which I never heard of. Very strange.

                    I did the nickel (1p coin) test with 18g and there was a tiny tiny mark, not even a full circle. Pulled the shot anyway and tiny drops seeped out. I then pulled another with 17g and again some water drops seeped. My grinder doesnt go any lower unfortunately and it took 23 seconds to get 38g of espresso, including 7 seconds of pre infusion. So it’s pretty fast and it doesn’t taste that great either. I don’t know what else I can do :/

                    MediumRoastSteam Yeah I think so, the flat side of the gasket is touching the group head and the side with a slight groove is facing down towards the PF

                      erkal - no! That’s the wrong way! The flat side needs to face the PF - I.e.: touch the basket!

                      MediumRoastSteam And, is the gasket the right way up? (flat side facing down)

                      Needless to say, before you put the dispersion plate and shower screen back, take a picture please… 😉

                        MediumRoastSteam Really?! Why have a groove that looks just like the rim of the basket and have it facing the flat surface of the head LOL. OK I can change that easily
