    Sunbeam Em0480 Grinder setting.

    Gene Cafe Coffee Roaster $850 - Free Beans Free Freight
    I have recently aquired a Sunbeam EM0480 grinder and have had a few issues with the grind. I have to have the setting on a few notches right of the Course 25 number so that my Sunbeam EM6910 pressure guage does not go into the red (and the coffee in the basket turn to mud); anywhere in the mid range and the grind is considerably too fine.


    I am using Lavazza Il Perfecto Esp. beans

    Re: Sunbeam Em9480 Grinder setting.

    Are those model numbers right, or do you mean Em0480 Grinder and EM6910 Espresso Machine? :-?

    Re: Sunbeam Em9480 Grinder setting.

    I have 2 EM6900s the previous model to the EM6910, the pressure gauge isnt all that accurate. On one the gauge sits just into the dark brown area and the other sits nearly half way into the Red area. Apparantly on the appreciation course they recommend having the gauge sit half way into the Dark Brown.

    With the muddy puck, you may find you need to updose (put more grinds into) the basket. The Sunbeam baskets are quite large compared to commercial ones. I use a LM basket sourced through Greg Pullman from Pullman Tampers, a site sponser.

    Dont take too much notice of the pressure gauge, basically you want to get the extraction to last around 25sec, just change your grind till you get this and everthing else should be fine.

    I hope this helps.

    There is a lot of information in other threads about the EM6900/6910 machines that you may find more info in.

    Good Luck with the journey.

    Re: Sunbeam Em0480 Grinder setting.


    Runfast, my grinder is much the same. But only after I moded it.

    When I first got it, the right spot was somewhere about the middle mark (between the "coarse" and "fine" markings), but after not very much use it wore quickly. Seemingly it got blunter and I had to set it finer and finer to achieve the same grind. Eventually, it was not fine enough any more, so i had to mod it.
    I added a thin rubber washer underneath the central conical burr, lifting it up a mm or two. Since I could not find a washer quite thin enough, the adjustment resulted in it shifting way to the other end of the scale and on the coarsest setting it ground a fine espresso grind. At the "fine" end it produced moon dust.
    After making a slightly thinner washer, and doing the mod again, the ideal spot for an espresso grind is now two notches to the right of the "coarse" mark (still off the scale, but with a few notches to play with to adjust coarser or finer". Since doing the mod, I have not had the problem of blunting or the grind changing over time.

    Ideally [as it states in the manual] the em0480 should be in the espresso zone in the 12-16 range.
    25+ is too high and indicates a problem.

    There are may posts about these kind of problems in the em0480, and ultimately its up to you whether you return it under warranty or try and mod it.

    Have you tried pulling it apart and reassebmling it?

    One other thing though, the 6910 can be operated with pressurised baskets or non pressurised baskets.
    For true espresso, you need to use the non-pressurised baskets.
    If you are using the pressurised baskets, then [assuming your grinder is operating correctly] an "normal" espresso griind setting in the range of 12 -16 would be far too fine for the machine.

    Re: Sunbeam Em0480 Grinder setting.

    When you refer to pressurised baskets do you mean the dual floor baskets?

    Re: Sunbeam Em0480 Grinder setting.

    yup

    Market research/experience shows that the "average" coffee machine buyer is not interested in developing proper coffee making skills, buying fresh coffee or owning a grinder.
    Hence the manufacturer needs to make the process as fail safe and easy as possible

    Pressurised [dual floor] baskets are generally used in lower end machines and make it possible for people who dont want to learn real coffee making skills and prefer to purchase stale supermarket preground coffee to get a good looking crema enhanced shot.

    Sunbeam have sensibly [from a marketing POV] provided both basket types with the EM69** range

    True espresso requires non pressurised baskets and the correct combinaton of grind and tamping pressure to create a a "coffee puck" that will yield a 25 ml extraction in 25sec at a water pressure of 9bar.....or thereabouts.

    Pressurised [dual wall] baskets usually have a tiny pin hole that creates the pressure [rather than the coffee puck] and it squirts out the extraction.....rather like shaking up a can of soft drink and putting your thumb over the top.

    You have a great machine & grinder, so you probably dont ever want to see/use those naughty dual walled baskets again.
    Hopefully, if you were using them, that may be the cause of the problem you reported.

    Re: Sunbeam Em0480 Grinder setting.

    Actually, they didnt have pressurised baskets with the original EM6900 and this caused a lot of disappointment for the normal users when they found their new $700 machine made inferior coffee with preground than the cheapy single thermoblock machines they had upgraded from.

    I had quite an involved discussion with Corey on CG about this (vs tampers) and it seemed someone at Sunbeam either came to the same conclusion as me or read the discussion and took up my recommendation with the later EM6900s and EM6910s.

    Re: Sunbeam Em0480 Grinder setting.

    Thanks,

    however i have been using the traditional basket with the grind problem.

    I have followed the advice from your post from a previous thread - take it apart - make sure adjustment collar is fully anticlockwise when the top burr goes in etc -

    the problem continued - at the post 25 course setting it was ok for espresso - any smaller number and it is moon dust!

    i only bought it yesterday at Myer - are they obligated to change it or do i have to send it to Sunbeam?

    Re: Sunbeam Em0480 Grinder setting.

    Others have had this problem [very high grind setting] and have opted for replacement.

    Sunbeam have a easy replacement policy, so Myer will be happy to replace it for you, perhaps just check by phone with the store to make sure they have a replacement in stock.

    Myer are pretty good at replacing things, but be firm/assertive in your description. ie the grinder does not work in the 12-16 zone as described in the manual.

    Once you have it all sorted, I suggest you try some beans via a site sponsor like Veneziano or Coffee Hit [both sell over the internet] they will be much better than the Lavazza.

    Good luck

    Im now on my third EM0480 (replaced twice). *The first two had the opposite problem, where gradually over the space of 4-5 months I had to lower the grind settings past the recommended zone to the point where it was on setting 1. *
    Now with the third em0480, it wont allow water to pass through the filter basket at setting 20 and lower. *Ive had it now for 2 months now, and the grinder is only marginally better than it was originally working in the +25 setting. *I checked the assembly from the instruction booklet.
    Im using with a Sunbeam EM4800 that has worked perfectly for the last 4 years. :)
    Thank goodness for the Myer replacement policy where they fully refund me first, then create a new purchase receipt (resetting the 12 months warranty each time).

    So, back for another replacement!

    Re: Sunbeam Em0480 Grinder setting.

    Well I rang Sunbeam and they went through it with me and decided that the calibration was out - told me to take it back to Myer for replacement; which I did. They were great - gave me a brand new one; the lady even owned one herself so she knew exactly what I was talking about.

    Got the new one home and vola, perfect grind first time.

    I am meaning to get my hands on some different beans.

    Thanks for the advice.

    Happy brewing ; ::)
