Subject: Mazzer Mini E
Hello fellow coffee lovers,

I have been owning a Mazzer Mini E Type B for almost a year now and
generally am pretty satisfied with it. The only thing that has been
bothering me for a while now is the enormous energy that is required
to change the grinder setting. The grinder dial is so difficult to move that the "stepless
adjustment" becomes more or less a stepwise one - small adjustments
are at best very difficult. I have read in other places (guess it was
on coffeegeek.com in the review section) that other people are
reporting that it takes a good amount of strength to adjust the
grinding setting, but is it really meant to be that difficult?

I guess I have two questions in this context:

- is it (a) my weakness or the (b) grinder?
- in case of a or b: how do I improve the situation? I once had to
take apart the whole thing and noted that there was some kind of
grease on the thread, but it wasn't really evenly distributed. Should
I apply some more and what kind of grease would I use? Somebody I know
suggested plain old vaseline.

Thanks!
Oliver

The problem with Mazzers is fine grounds becoming stuck in the threads
over time and making the mechanism progressively more difficult to
move. Changing settings between say espresso and french press grind
probably makes things worse too since dust is more likely to be trapped
between threads on going back to the fine setting. The simplest answer
is to regularly disassemble the burr carrier and make sure all traces
are removed from the threads and carrier assembly. Depending on your
usage, once a year is probably not often enough to do this; once every
three months would be better if you can face it.

Unfortunately, applying grease or other wet lubricant to the threads
exacerbates this problem since it encourages more grounds to stick to
the threads. At least one altie uses no lubricant at all on the
threads to avoid the problem, while others have recommended using a
food-safe lubricant. I use some pure graphite (obtained from an artist
materials supplier) that gives some lubrication without stickiness.
The mechanism seems smoother than with no lube at all but probably not
as smooth as when newly greased.

Unless you are very old and or have severe arthritis, it should NOT be
that hard to turn.

Too late now, I guess, for warranty work, and unfortunate indeed that
you spent big $$$ for the "E" gimmick.
