              Despite what the guage indicates compared to mine, the timing and look of the pour suggest way too fine a grind.

              Where are you located sampan?

                  im in Perth WA mate



                  Can you guys compare my results to your own owns include time settings etc?



                  below I did A simple water test if you could please compare with your results (flow, quantity, pressure etc) as well;

                  1 cup roughly 250ml of water using 2 cup single floor (ie the big filter with tons of holes) filter with 2 cup pour spout running continously completed in ~35seconds from button press to button press

                  attached is just the beginning and the end if you would please.

                      yep, your gauge is quite different to mine (end of your yellow is pretty much 12/1 oclock and a very short brown zone). I suspect you will have to grind coarser.

                      It has been said on here before and cant be repeated enough -

                      Start with Freshly roasted beans (if you cant find or cant be told a roasting date, most likely they wont be fresh)
                      Change only 1 variable at a time
                      Try and get your routine set so that that 1 variable is grind fineness

                      Grind into the double shot, tamp so that 1/2 the tamp is above the rim of the basket and try your shot. If too fast, grind finer, too slow, grind coarser, but next time you run your shot (with coarser or finer grind) make sure that your tamp / dose method does not change (IE still 1/2 tamp above the rim of the basket). Rinse and repeat until you find your mark.

                      Once you do this, you can then experiment with dosing (have been reading on home barista how down-dosing but grinding finer can significantly change a shot) and / or tamping techniques.

                        If that was my steam wand I would beat the user with a wet RAG...

                        1: Watched all avis..

                        As has been stated by just about every CS to date.

                        A: Too fine and or over tamped.
                        B: Even when it starts to run it is not good and thick etc  looks like channelling but restricted.

                        Conclusion -  BEANS / Grind and Tamp.

                        Your water test proves nothing as to the issue with your coffee.

                        Forget what the gauge settings were in the class...

                        Focus on the Grind, Tamp and aim for about 50 - 60 ml in aprox 30sec then when you can repeat it... Check the gauge... It will be about 12:00 or Maybe 1:00 at worse case on your. unit..

                        Quality of the crema etc will be a direct result of the quality of the beans..

                        From here, there is nothing else that I or others can do for you, unless you follow our instructions to the letter.

                            right thanks yall.


                            Im now waiting for my fresh colombians to come in.


                            then I will repeat and see what happens and update here. hopefully all will be resolved.


                            however how many on here did that gauge cal check ? how manys ended up being between the yellow and orangish? how many ended up being brown etc?



                            angermanagment; why was it that all the machines at the school were all at about the brown spot?
                            and Could it be just me or could i be right in saying that im sure the pour and flow was better when i first got it?
                            finally could there be something wrong with the machine?????
                            because if i when i get the new beans and still dont get the results ?

                            compared to the flow at school and those vids at youtube mine doesnt do that even at its best flow (based on your gauge cal check)

                              Have you made your grind more coarse? :-/

                                Can I prompt you to, rather than asking the same questions and getting the same answers over and over that you wait for your fresh beans to turn up and try it again. Once youve done that, we can start looking at other things.

                                I have a 6910 that is now about 4 months old, I have done the coffee school fairly recently (October) and my pour was about the same (on and off) as the one as I got in the coffee school - I still get the odd chanelling but this is to do with my tamp more than anything and my grind setting when using a new lot of beans.

                                However I had, and used, fresh beans once I got home from the school and not the dried out, stale old prunes that mask themselves as beans in the Supermarket or that are sold in GJs, Micky Ds, etc. These are nothing like the ones you use in the School (did they go through and show you a container of stale supermarket beans to sniff test as opposed to fresh beans...yuck to the old beans!) and you will never - I repeat, never - get the same results from a supermarket bean as you will from 3 day old fresh beans.

                                I would suggest you start on a grind of about 12 when you get your fresh beans and move up/down from there. My machine requires about 16 on my grinder and chokes up completely at 12 on fresh beans, but they all differ a bit.

                                Once youve done this, start comparing to our results. You will find that very few that have a 6910 and are posters on this suit use supermarket beans (and hence need to use the pressurised portafilter baskets) so we cant really give you a comparison.

                                However, we can once you have the fresh beans...
