    To achieve the same flow rate a lower dose needs a finer grind

    Ha! I've just bought the em7000 and use the breville smart grinder too. I just spent 90 minutes and 20-30 odd shots to come up with the same combo as you've said, 7/8 onthe grind and 18-20 sec time, give approx 19gms of coffee.... wish i had read more first!. I'm finding the pressure gauge is quite 'tamp' dependent too - hard to keep the tamp pressure consistent, c.f dose, grind etc... If i want less coffee, ie 16gms, should i use a courser grind? it's late and im getting confused....

    A spice grinder is a terrible way to grind coffee. You will get a very inconsistent grind size, leading to inconsistent extraction (the smaller grinds will become over extracted much faster than everything else while the big ones will be underextracted), leading to awful coffee.

    The advice offered here is generally pretty good and given for a reason - there are few shortcuts to good coffee!

    If you get good results from preground coffee it is a fluke and wont be repeatable the next day.

    You really need a grinder and freshly roasted beans.

    Thats interesting. I took some ground coffee (have purchased some small bags, different brands, that have been ground in case I get lucky) and put it in a spice grinder to try and get a finer grind out of it. Unfortunately the first one had the pressure gauge go straight to the red and the 2nd one just poured like every other coffee we have got so far - No crema and horrible tasting.

    The Sunbeam EM0480 is on sale at Myer at the moment for $160, was tempted to try it.

    Really packed in the coffee and got a better result. Only slightly better but it was so hard to get the group head on that I thought I might damage the machine + when it poured, water came out from above the group head so there was way to much coffee packed in. Think I need a more course grind.

    Any suggestions on the grinder - Ive been reading about them for a few days but there is so many conflicting opinions out there.
    You are correct, you will damage the machine packing that much coffee in. You are incorrect about needing a coarser grind, you need a finer grind.

    As for grinder, depends on how much you want to spend / how long you want it to last. At the cheaper end a Sunbeam EM0480 or Breville BCG820 will do the job but won't last forever. At the other end a Eureka Mignon, Macap M2M or Compak K3 Touch will do the job a bit better and outlast your machine. This Macap M2D is currently for sale on CS: http://coffeesnobs.com.au/coffee-har...nder-used.html

    Previous machine was a Sunbeam and it lasted 10 years. Made average - great coffee depending on different factors. Used every type of store bought ground coffee beans and it would still give you something drinkable. But with the Sunbeam EM700 I fear I have entered a world of pain.

    Using ground coffee from Coles, 2 cup basket (that came with the machine) and the coffee has no crema and is bitter. Tried a 1 cup pour on 2 cup basket + a manual pour. On the 1 & 2 cup button push pours the Pressure Gauge does not move. On the manual pour the gauge moved a few millimeters but only once the cup was full to the brim of coffee.

    So if we are talking beans + grinder to solve my problems (if thats the problem) I would have thought if the EM7000 is so sensitive there would be information in the using manual about not only using a grinder and beans but the actual setting for the grinder.
    No grinder is a precision tool that has settings based on exactly how far apart the burrs are etc, not even commercial grade grinders. Even if they were telling you a setting wouldn't be accurate as the grinder setting needed changes with the beans, also as the beans age. Commercial grinders will usually have a range they normally produce best results in, but it's not a super narrow range.

    Were you using the pressurised (or dual wall) baskets with your 6910? Are you now using an unpressurised (or single wall) basket? That would explain the change. With pre-ground coffee you really need to use pressurised baskets. Espresso is a science, but there is an art to it because everything changes with the beans.

    As somebody about to purchase my next machine and due to various factors explained in a different thread the comments above are a little concerning as I was thinkning that the EM7000 was the most likely candidate. I have had a 6910 for 10+ years and it has served me very faithfully. So is there a recognised issue with the reliability of the Sunbeam machines I am not aware of (apart from the difficulties of producing a good shot that is described in this thread)?

    An update: I returned the machine today :/.

    I thought I was over the hump: With all of the great advice here, I managed a couple of days of pretty good coffee in a row. I was pretty $#%$#% pleased with myself, had the process sorted. Figured I could then just make tiny tweaks from there to get to great coffee.

    BUT then doing all the same things as the 'pretty good coffee' days, I got '%$#^%$^ bad coffee. Again. Low pressure: watery & tasteless or right pressure: still watery, really bitter.

    Yesterday I bought more fresh beans in case the beans that worked the previous days had suddenly gotten 'too old' (WTF, come on!). This morning: Crap coffee AGAIN.

    So yeah, I give up.

    On the upside: HN took the machine back no problem (I bought it in early May, returned the first one after two weeks thinking there was a problem with it, have been trying with this one for another month).

    My EM9610 currently makes a noise like an airplane taking off as soon as I turn on the power (I don't even have to turn on the machine, it's like magic!), so not sure it can be fixed, but I'll give it a go.

    @Porca: I kind of hate you right now.

    Appreciate all the patience and advice regardless, so thanks.

    No swearing yet, I seemed to have fluked a few good ones in a row

    As the owner of the Sunbeam EM6910/EM7000 series of beasts for many years, I am here to defend the reputation of the beast. Of course there have been many issues with reliability (Quality Control) with these machines, but once you have a working machine, then making a drinkable coffee should be relatively easy.

    For me, the key to success with this beast is to :
    * Grind your own beans (I will let you determine the relevant Brand and freshness of the Beans)
    * Fill the Basket until it forms a slight mountain above the lip of the basket and then use your finger to tamp it down into a slight hollow
    * Complete the filling of the basket and then tamp with a good quality Tamper (one that is the correct size for the basket...the Sunbeam one may not be)
    * The final tamp should leave you just below the lip of the basket equal to the thickness of a 5 cent piece

    Focus on the things that you can control first (the dose/amount of Grind & the pressure of your Tamp)...the coarseness of the Grind is the variable that you will need to experiment with.
    Ignore the settings that others suggest on their Grinder (not that these settings are wrong....just irrelevant for you)


    As a side note, as others have said, I was surprised how different the EM7000 was from the EM6910. As another side note, the EM7000 was advertised for $499 at JB Hi-Fi today....not bad if you can get a working and reliable one.

    The double basket did it. Had a few good shots in a row now. Won't bore with the details of grind etc as that is different for most but a 30 second extraction is tasting great. Very happy now.

    When someone does that it just proves one of two things:
    1. They think they deserve the credit for fluking it first go; or
    2. They have no palate
