Topic: Bodum Antigua stop-start-stop (8 msgs / 335 lines)
1) From: Sharon Allsup
I've got an uppity Antigua ...
On every setting but the coarsest, it grinds for a second, then 
stalls.  Hitting the side of the unit causes it to grind for another 
second or two, then stall out again.  Holding down the little red 
arrow which marks the grind coarseness seems to help - when 
that's done, it only stalls once or twice while grinding enough for a 
vac pot full.
I've cleaned the grinder and burrs, so that doesn't seem to be the 
problem. It is (mostly) putting out a fairly even grind that 
corresponds to the setting chosen.  The coffee still tastes grand ...
Any suggestions?  The unit is out of warranty and the budget 
doesn't allow for a replacement - if this fails it's back to the 
whirlyblade until the old house sale contract closes.  Thanks!

When it stalls, does it continue to 'hum' or is it dead silent?  Dan

It's "dead silent", other than the timer.

Sounds like a loose electrical connection or a faulty on-off switch, even a
poor connection where you plug it in.  Ought to be easy to track down if you
open it up.  Please unplug it first, OK?  Dan

Mine does the same thing, but only at the very finest setting
This began after I modified it to get a finer grinding range for
espresso.   I solve it by holding down on the little red arrow,
or placing a book on the top of the hopper during grinding.
It is caused by a misalignment with the microswitch.  Since I
seldom grind at the finest setting now (after the mod) it is
not a big headache for me and I have not opened it up again
to see if the microswitch can be adjusted or if a bead of
hard plastic goo on the perimeter of the registration disk would
increase the diameter sufficiently to more easily throw the
switch.  Both are possibilities.
Now if someone can only remember the URL for the Solis
grinder modifications.  Otherwise you have to reinvent the
wheel.
The discussion earlier about the plastic mounting of the burrs
in a Solis 166 (same manufacturer) allowing excessive wobble,
led me to think that these two issues may be related.  Otherwise
simply pushing down on one side of the hopper would not cause
the microswitch to actuate .

I will write soon about my recent espresso experience in KC,
and my attempt to replicate it at home with the Antigua and
Krups, using the exact same beans as were being ground out
of the hopper at Bar Stephano.

Coincidentally, the following URL was posted just
today on alt.coffeehttp://www.kwilson.fsnet.co.uk/grinder_tweaks.htmThis is not the site I referred to when I did my modification,
but it is at least Antigua specific.  I'll post the other, more 
detailed, directions as soon as I find them.

Here's two more sets of grind modification instructions
I found via a google search.  I believe the second set is
a copy of the one I followed (but be prepared for some
faux pas).  I pulled something apart while the grinder was
upside down or something and was completely unable to
"take note of the red dot"  (I don't think the Antigua has
a red dot) or otherwise note the original position of the
white ring.
In retrospect, based on grind performance, I believe I
repositioned the white ring by 2 holes, but I don't know
exactly where I started from, only that it got better after
I figured out where the parts that fell off must have come
from.  Try to avoid that mistake.
Note also that the second description ends with a short
discussion of the microswitch.

Here's an older post I found:
Good luck - I adjusted mine as fine as it would go and it's still no
good.
<Snip>
and then have actually done it myself 2 or 3 times since then.  The
process is quite simple.  I will explain it BUT I will assume no
responsibility for damages!  :-)  Dismantle at your own risk!  If you
have any doubts call Kyle at 1-888-701-2020 and he can take you through
it himself.  Please forgive some of the "non technical terms" I have
used!
1. Unplug the Solis 166
2. Remove the Hopper assembly by turning counter clockwise (past the
coarsest setting) until it won't turn anymore and then lift straight
out 2. Remove the Grinding dial by pulling it straight towards you
(this can be done with bare hands and can be a little difficult).  Be
careful so you don't snap the dial and break it.
3. You need to remove the "cover" (big gray gray part of the grinder)
in order to gain access to the insides.  To do this you'll need to flip
over the unit over.  You should notice 4 slots (2 on each side) where
the cover and base meet.  You need to stick a small flat head screw
driver in the holes to release the cover locking mechanisms.  This part
of the process can be a pain but just be patient!
4.  Once you have released the locking tabs, slide the cover off.  Now
you will have access to the "insides" of the grinder.
5. You'll notice now that there is a brown colored cover (has the dots
on it that denotes grinding fineness/coarseness).  This is supported on
two sides of the grinder (diagonally).  This pulls straight off.  Pull
it off. 6. Look into the burr assembly.  You'll notice that the top of
the burr assembly pulls straight out (creme colored piece that is
straight edged on 2 sides and round on the other two sides).  Pull this
out.
We're almost done...
7. You will now notice a white ring that has 2 "ears" (as Kyle calls
them) on the top surface and 1 nub (my term :-) on the bottom part of
this ring. You will also notice that there are 4 places where there are
gaps where you can remove this ring.
Note: Make sure that this ring assembly is rotated completely counter
clockwise.
The 4 gaps should be approximately at 10:00, 2:00, 4:00, and 8:00.
This is if you keep the front of the grinder (the place where the
timing dial was) facing your chest.
8. In order to adjust the grind you'll need to stick a small flat head
screwdriver into each of the 4 holes to work free the white disk.  BE
CAREFUL that you keep the disk in the same place as you pull it free so
you can mark with a pen the original position of the 2 ears!  This will
help you return to your starting point if you adjust too far.
9.  Once you have loosened the white disk rotate the disk 1 or 2 holes
COUNTERCLOCKWISE (I would adjust no more than 2 holes at a time just so
I can adjust gradually).  Once you have done this, snap the ring back
down and reassemble.
That's all there is to it!  If you want to make sure you didn't turn
the ring too far, put back the burr piece and then the brown shield.
At this point try putting the hopper back in.  If it goes in great!  If
you can't get it on, you adjusted too far (this might help prevent a
headache once you get it back together...trust me! :-).
I hope this helps.  If there is anything I have written that is unclear
please let me know (or others feel free to contribute...) and I will do
my best to describe it to you!
Sincerely,
Mike
    I almost forgot...when reassembling and snapping the dial back on
(the last step).  Make sure the long straight piece is pointing
straight down at the "zero" mark.

alt.coffeeDate: 2001-04-13 05:20:07 PST Indeed, this modification is a lot
easier than it looks when you read it.  I have
a Solis 166, which is the same grinder.  I've made the modification, and
generally
grind at the second detent from the finest.  Over the last few days, I've
had to
gradually grind a bit coarser.  Last night, at my usual setting, I
completely
choked by Gaggia - as in no water flow at all.  Moved it one click, ground
some
beans, and voila! back to my normal ristrettos.  If this were a science,
they'd
make espresso machines that do everything for you.  (wait a minute... I
guess they
do...)
When you make the modification, make it large enough that you have some
adjustment
- i.e. you can go finer than your normal grind.  Some days, you'll need to.
Also, give up on using the same grinder for anything other than espresso.
Once
I've got it working right, the last thing I want to do is change anything.
Go figure...

Make sure the safety switch is pushed down fully on its mount.
The safety switch can be disabled by swapping the connectors. Replace them
on terminals 1 and 3, the normally closed position. But now the switch must
be removed from its mount and taped out of the way. The grinder will operate
with the hopper off, so pull the plug for any maintenance.
