  • Sunbeam em7000 coffee pressure gauge

    Hi all, first time poster. Just purchased a refurbished "as new" em7000 from Sunbeam outlet. First one was returned as hot water tap on machine turned on water to the group head. Second machine seems fine. I have pre ground Lavazza coffee at home and am using pressurized 1 and 2 cup filters. The coffee pressure gauge only makes it about half way to the optimal orange zone. I've tried slightly different doses and tamping softer or harder but still no luck. Is this still do with grind size? Or do I have another dud machine?

    There's your problem. Use non-pressurized baskets and fresh roasted coffee ground immediately prior to brewing.

      Did I make a rookie error and think the pressurized basket will fix all? Is freshly ground THAT much different?

        Yes, and yes.

          Freshly ground AND freshly roasted (less than 2-3 weeks since roasting).

          Cheers,

          Matt

            Okay, Got the grinder. You're right, fresh ground got to correct pressure no probs. However, now I'm slowly going nuts trying to get the right consistency when pulling shots. When the pressure is bang on, the coffee coming out is a tiny trickle, adjust grind to coarser comes out better with slightly less pressure but i can't seem to get that nice thick crema. It doesn't ooze out nicely like the youtube vids I've seen. Ive been persisting with Lavazza whole beans, do i need to up the quality of my beans to achieve that rich crema or is is it a grind and tamp issue???

                I was reading along feeling sorry for you because I know what it's like chasing the crema, then I read the word "Lavazza" and thought that'll do it. If you're not sure where to get beans, get them from here on BeanBay. Start with the Espresso Wow, see how that goes.

                  Thanks, I really appreciate the info.

                    Don't get too fussed if the creama does not ooze out. With fresh bean there should be a nice head of creama. Then there is the taste test. Timing of a ratio of 60 mls in 30 sec is sort of the starting point for grind, tamp and extraction pressure.

                          I joined to follow the thread because I've been having this problem as well: I cannot make a decent coffee with this machine after 3 weeks (I've had the EM6910 for 6+ years without a problem, so I'm really surprised and disappointed).

                          I've trawled the internet for advice, including the really long thread in this forum about it, but after 100+ attempts with different grind/dose/tamping, I can only get under-extracted and weak or over-extracted and bitter out of it.

                          I'm using supermarket beans also, with an EM0480 grinder. I appreciate that using fresh beans is better (of course), but if the machine is so precious that I need fresh beans for it to even work, I'll probably take it back.

                          Really looking forward to the results.

                            Supermarket beans are hit and miss. If you are using Vittoria mountain grown, throw them out. They pretend to be a $38/kg bean but Coles and Woolies have regular half price sales. My results with Vmg are exactly as you describe. Try Aldi $12/kg and Coles $5/250g, they actually work and taste reasonable.

                              Tried my first shot of Espresso WOW today after delivery...i was fairly rushed just to see if i could taste anything different. Was disappointed, I'll tinker some more but so far I'm happier with the taste of Lavazza with a pressurised basket (i can hear minds blowing already). I hope to get better results tomorrow.
