Need to calibrate your Mahlkonig EK43 or EK43 S? See the quick and easy steps in this video, as Ryan demonstrates using the tools that come with the grinder to properly calibrate an EK43.


Hey, guys. Ryan from Prima Coffee equipment here. Today, I'm gonna tell you how to calibrate an EK43 or EK 43S. One of the most common questions that we get in customer service regarding the EK is will it be calibrated for espresso? Can I pull a shot when I get it out of the box? The answer is maybe. They're set pretty close. Some of them are set a tiny bit differently. Fortunately, with the included tools, it is super easy to make these changes by yourself for either a finer range or a more coarse range. I'm going to show you how to do it. In the box, you're gonna find an Allen wrench and that'll be included in the accessory bag. And what you're gonna do first is just loosen the set screws on the adjustment knob. And you're going to turn them counterclockwise. Okay. There's two. So, just turn this a little bit, get to the other one. It should only take just a couple of turns.

Okay, now once that's loose you're ready to turn the center shaft which adjusts the distance between the burrs. So, I've got a pretty wide flat head screwdriver, I'm going to turn the grinder on. Now, what we're going to do is very slowly turn the center shaft until we hear those burrs meet and they'll make a really apparent chirping sound. And we don't want to leave it at that point. Once we hit it, we're going back it off just a touch. So, this is what it sounds like. And as you saw, I backed off just a touch. Once you're there, you're set up for grinding for espresso.

Now before we re-tighten the set screws, go ahead and just make sure the knob is in the finest position so that it matches the actual zero setting that you just set. Okay. And now we're going to go ahead and re-tighten these. Okay, there's one. And two. All right, and that's it. You can also do the opposite. If you do want a coarser range with your grinder, you just turn that center shaft to the left instead to get a wider range of coarse grinds. And that's it, that's how you calibrate an EK43.
