Subject: Braun 3045 burr grinder disassembly and cleaning
 

I've had this old Braun 3045 grinder for years, and it's finally started producing unacceptably coarse/uneven grinds at even the finest espresso setting.  So I decided to clean the burr heads....

The grinder appears to have no visible or hidden screws, and frustrated my initial attempts to access the interior. 20 mins searching the web for help on how to disassemble the grinder produced nothing but suggestions to run rice through it (which I'd tried).

Here's how I managed to access the burr heads (which I'm posting here for anyone else who searches for how to clean this grinder).

1) Remove the bean hopper (it pulls up and off easily).
2) The plastic grind adjustment ring can be removed by placing a flat head screw driver in the three slots around the inside lip of the ring, and gently pushing the tabs hanging down outwards and pulling up on the ring.  You may want to mark where the ring below the adjustment ring matches the adjustment marker, so that you know where to re-attach the adjustment ring later and keep the preset min/max adjustment settings.
3) The ring below has about 50 plastic teeth and locks the adjustment to each grind setting.  I can now be removed by simply unscrewing it counterclockwise until it comes loose.

I found that what was wrong with my grinder wasn't oil or grind build up, but rather that years of grinding had worn the blades down somewhat, and so that the minimum grind setting wasn't fine enough to make espresso grind.

I cleaned the burr heads and then screwed on the lower ring down until it was almost tight.  I then backed it off slightly and then reattached the grind adjustment ring so that the adjustment marker was set at it's min-point.

Hope this helps anyone else who's attempting to clean this model

(and yes, I know that I should probably replace this old grinder since the burr blades have been so seriously worn, but it's been relegated to our vacation house now anyway :) )

Thanks Scott, your post was very helpfull I've had the Braun KMM 30 (3045) for about ten years not and never did figure out how to take it apart. I did get it apart thanks to you and found about the same results as you the burrs were wore quite a bit but not really any excess coffee build up. When I pulled it apart Idid forget to mark and check how far the burr carrier was tighened down and I got the burrs just a little to close however it was quick and easy to adjust. Good thing I did just get a Baratza Virtuoso just right before I tore this Braun apart its really been a good depenable grinder but theres not parts to rebuild it and I glad I got the Baratza it much quiter and alot faster and more consistent.

Thanks Scott for the instructions.   With the new adjustment, I hope to get some more mileage from the Braun till I can justify buying the Rancilio Rocky to go with my Rancilio Silvia.  Hopefully none of my friends would like coffee from the Braun 4085 drip coffee maker.

This is really funny. I wasn't even looking for this information but just happened upon it while lurking. I too have had this grinder for years and I tried to open it up when I read this instructable about how to mod a Cuisinart grinder (which I also just happen to have) so it would yield a super fine grind. I ran into the same problem and stopped at removing the hopper (and spilling beans everywhere :) ) and instead concentrated on modding the Cuisinart. The difference is striking. I get an incredibly fine fluffy grind that almost (almost!) rivals that of my Major with an accompanying taste improvement. I don't really want to try it on the Braun but I'm hoping maybe one of you will be inspired by the instructable and try it on your Braun. BTW I'm the one who used the brass washer approach. That's where you'll probably get the most mileage. Please report back if you try this.

Thanks Scott for the instructions on taking the Braun apart.  I would add that the slots are the big slots along the edges, that you can see gear teeth thru, one at a time push out the tab and lift that tab over the ledge that it catches on.

And now I am happy to say I have solved an oft reported problem with the Braun, that it doesn't grind fine enough.  The solution is just to screw the upper burr down tighter when replacing it.  I went some more clicks, just until there was a bit of contact when spinning the lower burr (running the motor), then backed off one click.  Then set that as the finest espresso setting when reassembling.

Now it takes a really long time to grind!  Like, a minute to grind a double shot at the new finest setting.  It's a fine soft powder that I think is even finer than the Lavazza pre-ground espresso (ugh, that stuff tastes horrible) that I got (to verify my hypothesis that my grind was too coarse -- which before it was.)

Now, I have plenty of crema on my fresh-ground espresso!

Thanks Scott.  Your info worked and I may never have figured out how to disassemble the grinder.

I would like to add that you can cut off the two rectangular tabs that hang down from the ring that perform as stops between the fine and course settings. That way you can simply unscrew the whole bean holder assembly from the base WITHOUT going through the disassembly Scott describes each time you want to clean it out. This is exactly how the previous model works. Shame on the Braun engineers for redesigning the grinder so it cannot be cleaned thoroughly without Scott’s instructions.  It was amazing what an accumulation of bean residue I found when I got the grinder apart. New life for my venerable grinder. Thanks again Scott and Artichoke.
