Question about Gaggia MDF Electric Burr Grinder

1 Answer

MDF very coarse grind

After 25 years of flawless operation my MDF started misbehaving. No matter how I turn the dial the result is the same - very coarse and uneven grind. No change in the motor sound though. Any suggestions would be appreciated.

Re: MDF very coarse grind

Several possibilities loom:

1. Same burrs for 25 years? don't be cheap replace them!

2. Dirt in the threads of the burr carrier, or the threads that recieve it?

I have a Gaggia burr grinder, Brevetti Gaggia SA Model MDF, s/n 7262. The handle that you flick back and forth to let the grinds come out broke off inside the unit.fixable? 707=837-8916 Thanks Anne

Look inside the grinder, The lever is attach to a SPRING .
May be the lever is disconnected (unhooked) from the spring.


It cost you about $15-$30 for the parts.

Ground coffee does not come out

Try this, unplug grinder, vac out all beans, then turn grinder towards fine until you cannot turn the big nut in the center of the burr chamber with your fingers. Now turn adjuster towards coarse until you can barely move the middle nut(you should hear and feel the burs touching) now if you look around the edges of the adjustment ring you will see notches, pick a spot any spot just remember where you started, then turn 14 notches towards coarse, your grind should be almost perfect.

How to calibrate my Bunn grinder.

It would be easier to pick up the manual in the commercial section under products from, rather than me explaining it.
You have to loosen the nut on the adjustment wheel, then pull out slightly and turn towards coarse a few numbers, then push back in and turn grinder on and slowly turn toward fine, until the burrs slightly touch, you will hear a little metal on metal, at that point turn the grinder off, back off about slightly, then pull out adjuster and turn it to Turkish and tighten screw.

Does not grind evenly When I try to grid a coarse grind for french press coffee I get a lot of small grinds.

I was a little confused at first but where ir says coarse on the adjustment "wheel" is actually the fine setting. If you want coarse you need to turn it the opisite direction. If you look cloosely you will notice there is an arrow beside where it says coarse pointing to the right and beside where it says fine there is an arrow pointing left. It kind of makes no sense, but I guess since they've been making it for like 70 years they figure why fix it. I hope this helps, I had the same problem the first time I used mine, and the manual doesn't really mention it.

Parts and Grind Selection

The current Kitchenaid A9 burr grinder glass jar is interchangable with the original Hobart/Kitchenaid A9 glass jar; therefor, the gasket should also interchange - contact Kitchenaid customer service to order a gasket.

Setting the grind is accomplished by grasping the body of the ginder in one hand and the grind-selector ring (collar that the jar screws into) in the other. Hold the base tight and turn the selector ring clockwise for a finer grind, counterclockwise for coarser. Be careful not to completely unscrew the selector ring; if you are not sure how much adjustment is left, screw it all the way clockwise until it stops (finest grind); then, back it off, up to one full turn to make the grind coarser.

The selector ring has the words coarse, medium and fine cast into it; these are rough postition markers. There is a triangle cast into the body of the grinder, just above the brand name, that can be used to diral in a preferred level of grind. I use a medium-coarse grind for drip coffee makers; to do likewise, position the selector ring so that the triangle is pointing midway between the words coarse and medium.

Grinder setting stops at drip. Can't turn further to espresso.

Another suggestion is while the grinder is off, turn it up side down and rotate the bean hopper from coarse to fine a couple of times. This will clean out grounds that have gotten into the threads and it will prevent the bean hopper from not turning to a finer grind.
If you start to get a clog in your grinder, open it up to a coarse grind for a few seconds. The coarser grind will clean out the chute and then you can turn it down again while it is still grinding.

Grind setting

This grinder is really pretty crappy, I have the same one. If you want anything less coarse, you will have to grind it multiple times. My Grandmother tried using this and it ended up spitting out a few half and whole beans even after grinding. The best you would end up getting would be a drip coffee grind. Check this out, it might help understand the problem:

Love your 'handle'!

I'm thinking that there is something in the burr in the unit. Empty the unit and remove the burr. Usually, this is done with a counterclockwise turn. Note how hard it may be to'll have to reverse this when you put it together. Now, clean out any coffee debris you find. Then, turn the unit over and tap it on a firm surface covered with newspaper. Reassemble and return to service.

It could well be gummed up with years of coffee bean residue

Very simple to take apart. There are two screws holding the cannister. They are hidden under 5mm round rubber covers that you have to pry off. Then remove the two screws holding the plastic cover. Mark the position of the numbered dial relative to the brass burr assembly then remove it. Once exposed, you should be able to figure out why it is locked. Scrape away as much gunk as you can.
