    Sunbeam emo450 damaged burr??

    Gene Cafe Coffee Roaster $850 - Free Beans Free Freight
    First of all Id like to thank everyone who uses these forums. Im a home espresso virgin and have found this website to be a great resource.

    I just bought my first machine and grinder on Thursday. Based on my research here I settled on the Breville Ikon and Sunbeam emo450 - my understanding is that these are the bare minimum to make decent espresso.

    The first thing I did with the grinder was take it apart to see how it works inside. I noticed a nick in the bottom stationary burr but decided that such a gross defect wouldnt have passed QC if it would cause a problem. So I gave it a go anyway but had a terrible time. On the recommended 12-15 setting the grinder was incredibly slow (I didnt bother waiting but it would probably take 5 minutes to fill a basket! that cant be right can it?? ;D).

    I have to run the grinder at the coarsest setting (way past the 25 setting) to get a 60mL/30sec shot (thats with a single walled/unpressurised basket and a light tamp).

    So Im just wondering if Im doing something wrong? Hopefully its just the grinder; Id like to get a refund and buy the shiny stainless steel emo480 anyway ::)
    Ive attached a few photos of the offending burr. I also noticed that the bottom burr is very sloppy; I know that these machines arent perfect but it seems way too loose. What do you guys think?

    Way too slow (I have one).

    Maybe its the sloppyness thats causing your problems.

    I took mine apart the other day for a different reason.

    What do you mean by sloppy?
    Movement up/down?
    Able to tilt off the vertical?
    Mine is fairly new and has no movement.

    It is sloppy side to side; tilts off the vertical as you put it.

    Im more surprised by the nick in the burr. Is that something to worry about?

    Im guessing the nick would cause a very minor variation with partical size but the sloppiness is obviously a bigger problem.

    Seeing as its new Id be taking it straight back and asking for a replacement.
    Check the replacement too before accepting it.

    Im guessing its not seated right somehow and you dont want to be voiding warranty when you dont have to.

    Took back the 450. They were going to give me a refund but I noticed a 480 on their shelf; even though when I was there on Thursday they insisted that they didnt have any in stock :-?
    I checked it in the store. No nicks this time but it too has the side to side movement in the lower burr. It was the only one they had so I took it anyway. Looks a lot better considering they only wanted an extra $20 for it.

    Only played with it for a few minutes but it looks like itll be a keeper. Probably will be using it on a 10-15 setting for espresso instead of the 30+ on the old one!

    As to the lateral movement Ive found this:
    http://coffeesnobs.com.au/YaBB.pl?num=1183436456
    "...from new these grinders have a lot of lateral movement in this shaft therefore resulting in an uneven grind..."

    So it looks like you must have been luck with yours 8-). I might try some of the modifications recommended above but I think Ill live with it for the time being.

    One more newbie question: when timing shots when do you start the clock? From the second the pump kicks in or from the moment you get the first drip?

    Cheers,
    Matt

    From the second the pump kicks in.

    You might get up to about 8 seconds before seeing the first drips.

    Gday matt84,

    Welcome to CoffeeSnobs mate.... [smiley=thumbsup.gif]

    Id take that EMO480 back too if I was you. Any movement as you have described is a fault and probably indicates that either the top motor/gearbox bearing has or is about to collapse, or that the bearing is actually a loose fit within its housing. Either scenario is an indication of failure though and would make trying to produce consistent particle size spectrum suitable for excellent espresso almost an impossibility.

    You never know, that grinder you saw on the counter may have been returned by another dissatisfied owner which the store staff forgot to send back to Sunbeam.... Who knows? There should be absolutely NO lateral or axial movement of either the rotating burr or the fixed burr. Any such movement makes it impossible to produce accurate, repeatable results. Maybe you should consider getting a refund and then talk to one of our Sponsors about an Iberital Challenge or a La Spaziale Junior. Either of these are very capable grinders and would provide you with years of excellent service.

    All the best Matt :),
    Mal.

    As I said in my first post,
    "Mine is fairly new and has no movement."
