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?

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

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.

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).

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.

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

When you do this, is this with the motor running or stopped?Originally posted by iggs View PostI'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.

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.

EA

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.

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 [emoji4]
