    Unhappy Mazzer Super Jolly dramas - not fine enough :(

    Hi all

    My super jolly isn't grinding fine enough. It is causing me much sadness

    I picked it up second hand, got new burrs and a service, but then had to put it into storage for a while.

    I pulled it out recently and can't get it to grind fine enough! (its also out of warranty repair period so can't take it back...sigh. And it's not a site sponsor cos I'm up in Bris)

    I've tried taking the top burr collar completely off, giving it a clean, and winding it back down again till the burrs are touching, then turning it back a notch. Even then, the pour comes gushing out.


    Any ideas are much appreciated. The fate of my coffee delight is in your hands my friends!

    Weird . Any play or movement you can detect indicating worn bearings? Check you have correct burrs installed to. Burrs can be made for clockwise or anticlockwise motion too. If you buy aftermarket you need to make sure you get the right ones. The normal caveats too if you installed them to make sure that no muck is behind them and all is tightened up.

    Iím no engineer but worn bearing will have friction, noise, maybe clicking sounds as well as movement. Just rotate by hand, it should all be silky smooth. It should spin up quietly and so on. Take out the burrs and carefully check the numbers match the bearings for your grinder.

    the shop I got it serviced at installed them for me. these guys should know what they are doing but I can't guarantee it! any particular thing I should be looking for in terms of burr installation?
    movement seems smooth?
    when you say "Take out the burrs and carefully check the numbers match the bearings for your grinder." what do you mean by that sorry?

    javaphile:
    using my normal freshly roasted beans I've always had. I switched from my old Bezzera grinder which got a perfect shot to this the next day with just gushers, so I don't think its' a bean problem.

    I agree if the shop installed the burrs all should be well. The best thing would be just to take it to the shop and get them to test it.

    unfortunately they want to charge me $88 to even look at it because its outside of "warranty repair period" and that's the labour costs. I'm not happy about this.

    going to take it to somewhere else if I can't resolve this myself.

    In your court then. Check direction of rotation, remove the burrs and make sure correct burrs were but in. Hopefully you paid for and got genuine Mazzer burrs.

    Remove the burrs and verify that they're flat and with no debris under them.

    Hi Iggy....did the shop specifically say / refer to that they ran some beans thru the grinder and pulled some shots with it?
    And did they give you the old burrs back?
    Said it's all good to go?
    If not they should have.

    I've got a SJ as well, and they might not be the absolute best grinder on the market, But they are rock solid and once dialled in to a fresh and consistent bean / roast IME are easily 'readable / adjustable'.
    The one thing I luv about mine is its repeatability. But then any grinder at this level or above I would expect will be similar.

    Try this ....Turn it off. Disconnect cord. ** Mark up your adjustment ring where it is currently adjusted at.
    Turn Adjustment Ring (AR) AntiClockwise till it locks up ( zero point).
    Now turn it back around 1hr 30min ( ie from 7 o'clock to 8:30 say) on the clockface.
    The AR has 10 numerals marked on it with 10 'notches' between each numeral around its circumference.
    1 1/2 numerals equate to the above
    That will be about where to start dialling in, if the grinder is serviceable and in good condition.
    And where my SJ is dialled into an E61 grouphead machine using fresh home roasted beans in a Behmore.

    If it is all lot less than that it could be the repairer has not repaired it to OEM stds.

    Iggy I'm in Brisbane as well. And having helped another CS member recently I'm happy to compare SJ's and try
    to diagnose whats going wrong for you.

    I've got a few ideas but will keep them of the forum here till it can be confirmed.
    Pls PM me if you cant find the issue, need some assistance.

    Hmmm...
    Big assumption, that.

    Very good instructions from EspressoAdventurer
    Just to add to that, make sure when you turn off the grinder, and go looking for the zero point, ensure that the grinder is completely empty. Especially in the grinding chamber. This is done by removing the top burr and cleaning it out.
    As you can imagine, you can't find zero point if there is a bean wedged in between the top and bottom burrs

    Thanks for all your advice everyone

    I've stripped it down removed the burrs, cleaned up everything and replaced burrs making sure they are flat. found the zero point and calibrated as per EspressoAdventurer's instructions but no luck :-(

    Any advice where to go from here?

    EA: your offer to help personally is very kind. I may have to take it up if I can't resolve this on my own!

    I've learnt a valuable lesson in not testing out a serviced machine straight away. sigh.

    Have you checked the part number on the burrs?

    First off - Well said by U2 in post above ...to true.

    Iggy, the Sj is built like a Mack truck... with new burrs installed there should be no issue.
    But its not.
    So assume nothing at this point. Start at the beginning and follow the flow chart.... so to speak, all the way to the end.

    1/ Check that the Burrs are sharp....run your finger nail across the face OF both burrs all the way around.
    Sharp? will feel like it wants to cut you. Old = dull rounded feel and of course chipped etc.
    2/ The SJ motor runs / turns clockwise....So with the bottom burr in place, its cutting face should face to the right
    AND the bottom burr opposite direction.*
    3/ Check again when you refit the top adjustment collar that the zero point is close or preferably matches
    the ID marks you placed previously. Just that consistency reinforces all is correct and proper !

    * Now as something weird is going on here ...
    The SJ runs 64mm flat burrs, and As The Mazzer Grinder Co. were a spin out of the 1st Gen of the Fiorenzato Grinder company and all its tribulations.
    And Fiorenzato (in all its many company setups over the years ) Run both Left AND Right turn 63mm burrs sets across the many versions of its branded grinders over the years. And AS well do many other companies.
    The 63,64,65 mm burr set seems to be the common dimension for the base commercial grinder setup.

    Now Don't discount that something crazy is not going on here .... ?? Like ....
    Like a left turn set of burrs have wrongly been fitted. ? Huh?

    I've seen most everything in my mechanics days.
    Wrong Part put back in the right (part numbered) packet. OR
    A first day on the job newb ....'aaahg jus fit these to this umm aggh whats it again you know aaagh grinder'.
    And then proceeds to fit a right turn bottom burr And the wrong turn top burr.
    Anyway just check it.

    Iggy my experience with the SJ, and others here who have posted many times over the years are that they are rock solid.
    So it can't be too much...Remember one day this will be the tale of many laughs as you sit down and enjoy a coffee with your friends.

    ps the offer is still there to put like with like side by side to help you work it out.
    pm me if it turns out ...as status quo

    When you do this, is this with the motor running or stopped?

    Have you tried grinding and turning the burrs finer until you can hear chirps? The grind coming out should feel quite fine, like gritty flour.

    The other thing I have done previously is turn the burrs finer (grinder off) and go beyond touching so they are forced somewhat (within reason) together. This helped an old grinder stop doing what yours is doing.

    Cheers

    Just a quick question (not trying to hi-jack the forum) but with the Super Jolly & a packet of new burrs can you fit either burr on top and either on the bottom?

    Or is each burr different? (one is made as a top burr, one is made as a bottom burr)

    I just fitted a new set without really checking..

    Cheers.

    With the obvious exception of conical burrs, in almost every other (flat burr) grinder the burrs come as identical pairs, and it doesn't matter which one is installed where.
    About the only exception are Cunill burrs, and even those are identical other than mounting method (top uses 3 x screws, bottom uses a bolt and washer to clamp the inner edge of the burr down).

    Hi all. quick update.

    Apologies especially to EA for not following up - the busyness of life really got the best of me so this was on the back burner (I was using my aeropress and hand grinder to tide me over)

    Due to time constraints I eventually decided to just pay and went to an alternative (and ultimately more trustworthy) coffee servicing place and they diagnosed the problem as a burr problem. They replaced the burrs and did some test runs and its good as new now!

    So in short I got swindled by the other place. They 'replaced' the burrs but they were defective. I'm thinking about following this up with them when I get a chance, but to be honest, I'm a little over it.

    Thanks for all the advice and help along this frustrating journey.

    Glad to hear that it is all sorted now though...
    At least, you know now what the issue was.

    Not going to say name and shame but you would think a simple burr change couldn't go wrong, when they said defective can you elaborate? old or incorrect?
