The Gaggia MDF Coffee Grinder is a commercial grade burr grinder equal to those found in Europe’s espresso bars and restaurants. Automatic dosing allows a premeasured amount of ground coffee to drop directly into the filter holder. Pull the lever once for one cup espresso, or twice for two cups. Precision-machined grinding burrs can be easily adjusted for 34 different degrees of fineness. The large hopper holds 10 ounces of coffee beans. Easy to use and perfect results are achieved each time. Please note that most grinders are tested at the manufacturer and coffee grounds may be found in the grinder as a result. All machines sold are new unless otherwise clearly stated. Available in Black or White.


Features & Benefits: Coffee

Durable Construction

The housing is made of impact resistant plastic to help reduce noise and increase durability.

34 Grind Settings

The Gaggia MDF can grind fine enough for any espresso machine and coarse enough for drip coffee. To adjust the setting just turn the bean hopper and you can visually see what setting you are on through a display on the front of the grinder.

Heavy Duty Motor

The 100 watt motor on the MDF is connected to the grinding burrs through a gear reduction system. This gives the grinder more than enough torque to handle any high volume home use.

Top Quality Grinding Burrs

Like the other grinders in this price range the MDF has commercial quality grinding burrs that will last for years. They are 50mm in diameter and made of tempered steel.

Easy to use Controls

The MDF has a standard on/off switch that is located on the bottom right side of the grinder.

Large Capacity Bean Hopper

The bean hopper can hold up to a maximum of 10 ounces of beans. It is made of smoked plastic and has a tight fitting lid to help preserve the freshness of the beans.

Dosing Grinder

The ground coffee container for the dosing section is made of smoked plastic and can hold up to 8 ounces of ground coffee. Each pull of the plastic handle will dispense about 7 grams of coffee from the ground coffee container. Use one pull for single shot and two pulls for a double shot.

Is the $30 special available on this unit?

Jeff G asked:

I used grindz to clean it, but it left such a large amount of residue that I need to open the device to clean it out.  


I lifted off the protective rubber pieces hiding the screws inside the hopper, then unscrewed the screws and the hopper would not come off.


Can you please help?


Answer by Sanfam:

The hoppers on these can be fairly stubborn to lift out, especially if you haven't done so before.  I would suggest giving it another go, making sure that all hopper   screws are removed.  

Pat F asked:

I just got a Gaggia MDF and it is almost impossible to get the lid off the bean hopper.  I know this sounds stupid, but my husband and I worked for about 20 minutes just to get it off and now I'm afraid to put it back on.  Is this something that will work itself out, or do I need to return the machine?

Answer by Sanfam:

Just to verify, are you referring to the black plastic lid on the clear bean hopper, or the half-circle lid on the grounds hopper?  In either case, both simply sit loosely into place; Neither should be firmly held in or secured in any oither way.  

I have a Gaggia MDF that I have used for almost two years without incident -- until today.  It seems the switch to the machine has failed.  But I cannot remove the switch.  The screws attaching the base plate have an unusual head on them, and I don't seem to have any screwdriver or similar device that can fit them.  Is my best or only option to send the grinder back to WLL?  Has anyone else encountered this problem with the switch?  I noticed that the switch area seems to attract coffee grounds, which affects the "fit" of the switch in the on or off position.  Any guidance would be appreciated.

Answer by Todd Salzman:

I have to assume that the grinder is not working at all.  Most likely the problem is a fuse that is attached to the motor and not the switch.  It is a little difficult to get to but if you want to try you can go to home depot and get a set of Torx wrenches and use them to remove the bottom of the grinder.  Then you will see a control attached to the side of the motor. This control will pull right off and on it you will see a fuse holder.  Radio Shack will have the fuse.  Or you can send it in to us and we get it fixed up.

Answer by Christian Haugsby:

I did as you suggested, got Torx bits, removed the base plate, and replaced the fuse.  Machine does not turn on, so I have to believe that the fuse was not the culprit.  Would the next logical step be to purchase a replacement switch for the MDF, or do you suggest that I box up the grinder and send it back to you for repair?

DLK asked:

Is this a good grinder for a pot of coffee?  thanks

Answer by Erik:

Yes it certainly is.  This machine will work equally well for espresso, drip, french press or pour over!

dmbre25 asked:

I am usually pouring 2 double shots a day using my Gaggia MDF grinder, Gaggia Classic espresso machine, and very newly degassed beans locally roasted. The results are immaculate.  I am looking to expand my horizon to include Turkish/greek/boiled coffee (whichever name you prefer).  I have bought an Ibrik imported from Turkey that is a nice copper design and very traditional. My question is, if I zero in my Gaggia MDF grinder will that result in a grind that is powdered enough for a perfect turkish coffee?  I have read many reviews about the MDF that claim it can but all turkish coffee drinkers claim that the powdered texture necessary can only be achieved through hand grinders or using a mortar.  Any input would be very much appreciated!

Answer by ShaneAncefsky-Sales:


Although, I have used the MDF to do a turkish grind, I would not suggest it, Like most grinders in the home range, I find it does an ok job.  As you have found though.  A good hand grinder will do a better job of this.  That and you wouldn't be trying to recalibrate for an espresso shot or have to clean the doser of the powder.

Jeff G asked:

Hi all. We are looking for some buying advice. We are considering the Gaggia MDF grinder, but also the Breville Smart, and Baratza Virtuoso Preciso (possibly refurb). We will use the grinder almost exclusively for espresso. We have a Gaggia Baby we got from WLL last month. (not to make it more challenging, but if I could get a Rancilio Rocky refurb, I'd consider that as well.) Thanks in advance for your insight!

Answer by John Seymour:

I used the Gaggia MDF with my Gaggia New Baby for over a year. It is a great little grinder. You can get a good grind for espresso with it. The others I have no experience with. I would say read the reviews of the different grinders on the Whole Latte Love website and get the best grinder you can afford. The grind is very important for great espresso.

Anis asked:

I re-calibrated my Gaggia MDF last week-end so that 1 matches a notch over 0 (when Burrs touch). I am only able to get a good espresso grind with setting 2. I hear the recommended setting is "6" and I just don't understand how it is possible to get a decent espresso grind with that number as for me it is just too coarse. Does that mean I need to replace the burrs ? I've only had the grinder for a few months and don't heavily use it.

Answer by techkathy:

Sometimes the grinder can seem like the burrs are touching when they really are not. Listen for the sound after you clean out the grinder and run it for a second to check calibration. If the grinder is at the absolute zero point the sound will stop immediately. If it is not at the absolute zero point then the grinder will make a sort of winding down sound.

Answer by Brian:

I experienced the same thing...my MDF ground at 3-4 out of the box for a good espresso. With the coffee I am currently using, I am at a 1-2 for a good shot, although 1 can choke it if I tamp up to 30lbs.

On a side note, my grind is something like 30-45 sec for 14-16g. Is that normal?

pjay24 asked:

Hello. My MDF doser lever spring broke. Two questions, is the spring part available from WLLL, and does WLL have instructions on how to replace the spring?

Answer by mjackson:

It is available and if you call our tech support line they will be able to help you get the part and send an email on what to do.

philip asked:

how much beans should i grind for 2 shots of espresso on the MDF grinder, I just dont want to leave extra coffee in the doser. I have a gaggia classic.

Answer by A:


The starting point for a double shot would be 14 grams of coffee. The way I always use the MDF is this:
Let it grind for 10 seconds
Pull lever to dispense ground
Every second or so pull again until portafilter is just about full
Turn off grinder before your last pull to fill the portafilter
Give it one last pull to top it off

That should keep as much ground coffee out of the hopper as possible.

Jason asked:

plugged a gaggia mdf which I bought from whole latte love during thanksgiving with 110V into a 220V socket and I suspect that fuse may have blown. please help, new machine that i hope to repair myself.

Answer by Sanfam:

While it's possible the fuse may have blown, it's also possible that the motor may have been damaged by the higher-than-expected current. The machine can be opened by removing the four screws from the lower base, then removing the fuse from a black holder mounted to the motor's control board. These fuses are presently available from Radio Shack, listed as Part Number 270-1052 (Fast-Acting Style). For this sort of service, I would advise calling into the Technical Support department to discuss how to resolve it safely if you have any concerns.
