MAHLKÖNIG - E64 WS

Thank you this is really helpful. I have not had a similar experience and gbw on my grinder has always been roughly above 0.3-0.5g, even after calibrating multiple times with a 1kg weight. Reaching out to Mahlkonig currently to see what they think. It wasn’t a flag for me initially bc I thought the grinder needed to settle but I’m finding that the gbw system should be extremely precise out of box and even after calibrating.

So, the grinder is setup and grinding. Coming from a Eureka Specialita Turbo no tears yet. Look, I enjoy gatekeeping from time to time as much as the next guy. I get it, it's not a $3K Mahlkonig, it's not built as robustly as commercial machines, and the location of final assembly is different. Having gotten that out of the way, if given the choice of a $750 Libra on a flawed Mignon platform, or this for a few hundred more, you will have to begrudgingly agree that the choice is rather simple. Eureka charges > $1K for the Atom, same flawed platform, same sparse features. You get most of what makes the big boys great, the OS, DDT, local cell, GBS, in a price that is palatable for the average home user. And to be fair, you also get the retention that comes with a flat burr hopper fed grinder. Frankly, I think the price point is right on the money. Unless you are the proud owner of a E65 and still making payments on your credit card, I really don't understand your obsession with railing against this product. My complaints with it, for others who may be interested, are exactly the same as other posters: 1. The manual is terrible. That's because you have to scan QR codes to get into the detailed software and hardware manuals. The included books are useless. 2. The chute slides to its lowest position during the grind causing the grinds to fluff up on the upper fork. Not good. I have to jam something behind the chute as another owner did. F

Hey. So, the E64 is doing great. Excellent GbW, nice aesthetics, gorgeous large screen, and tactile scroll wheel. Used the onboard app to dial in a new bean, not rocket science but it got it there quickly. Overall a really nice, relatively quiet grinder, with excellent countertop presence and aesthetics.

I am SN 130 I would try another one. The other two grinders are nice and I’ve considered the Fiorenzato, but don’t have the UI large interface GbS and trick tech. Coming from a Eureka this is a step up, but then again so is the price tag. Mahlkönig has a 10% code as well.

I'm also an owner, yeah the Disc Distance Tech ("DDT") is very space tech. You change a the distance and then hear a slight high-pitched buzz as the discs adjust. What's interesting, to me, is how it's able to adjust for a finer grind, with left over ground up beans inside the burr chamber. I don't hear the burrs crushing any beans as they adjust.

Hey. I just unpacked my black E64WS. Grinder is great, light years ahead of Eureka's grinding platform, but noise wise, these two are pretty comparable. The Mignon series really were quiet. My biggest complaint is that the silver grinds chute will slip and revert to its lowest most position during the grinding process. This causes the fluffy grinds to clump up on the upper fork, and not neatly in the PF. I have to hold the chute with a finger to have the coffee clump in the PF only. My serial number is between 100 and 150. Another owner stuck something back there, and it looks like I will have to do same.

Just got my E64 WS today and it spits grinds all over the place. A rather obscene amount that persists no matter the beans. 😣

Thanks. It is a big disappointment that this is happening. I guess this is what I get for compromising on my initial quest for GBW Italian made grinder. I wasn't aware of the Mahlkonig manufacturing being done outside of Germany for the E64 WS. But now I am. lol

After reading all of the trash talking because of the secondary manufacturing I was expecting a cheap-ish build quality. I was pleasantly surprised with it being quite the opposite. I opted for a refund while the bugs get sorted out. I'll look to go with something different. The Mazzer Mini G and Fiorenzato F64 EVO Pro are the two that I'm leaning towards. What is the manufacturer date of your E64 WS? Mine was 11/2025 with a unit number of 195.

I am stepping up from a Eureka too. The Eureka Oro Mignon single dose. Prior to stumbling upon the E64 WS I was leaning heavily towards the E65W GbS. Totally overkill for home use, but YOLO.

Ahhhhh funny you mention the Ceado Rev. For a hot minute that unit was top of my list. Since it wasn't available at the time I ascended deeper into the rabbit hole in search of GBW grinders. Fortunately I have no height restrictions on my counter so my options remain wide open. Decisions. Decisions.

The newest models from Mahlkonig - grind by weight, home grinder. E64 WS. 😇😇😇😇 Absolutely beast of a machine. Still needs time to get the software up to date etc. it’s only a 3 or so weeks old. I absolutely love it.

E64 WS :) the newest home model grind by weight from Mahlkonig. Just came out less than a month ago

I had two grinders - Mahlkonig E64 WS which does all the espresso. Timemore 078s for decaf. And I have two had grinders - kingrinder K7 for pourover and a kingrinder P1 for aeropress. But let me tell you, I’ve only accumulated this because the Timemore Sculptor I’ve been trying to sell but don’t know how to, so just kept it (if you’re looking to buy in Paris lemme know 😂) and the hand grinders have been travel ones that now serve a purpose at home, though, they’re primarily for my travelling.

I never turn my own off. It just goes on to standby and the screen turns off but it never turns fully off :) my gripe is that the cloud doesn’t work. MK didn’t fix that before sending it out. So I can’t create recipes and push it to the grinder. Other than that, it’s great.

Received mine over the weekend. I’m really struggling to get the manual GBS working and to prompt me for the brew time. In the recipe I have Brew Time Input enabled with a time of 28 seconds. However after grinding finishes it just goes back to the main screen. Nothing prompting me to enter the last shot time. Could you share your recipe setup. The two options I have are Enable GBS or Brew Time Input. If I select GBS I don’t get any option of a manual mode so I’m guessing that it’s the Brew Time Input. TIA

Prob the biggest peeve at the moment. All my recipes stuck in pending for last 2 week

Been playing with mine. It’s a beast! Calibrate with 1KG weight weekly for best accuracy on loadcell per the manual. I’ve been getting accurate up to .1g every shot. The “manual GBS” mode is sweet!!! It’ll ask you to input the real shot time for the last grind and will auto adjust for your next go. Edit recipe, choose recipe, brew time input. You should enter the standby time in the settings. It’ll auto standby and can choose an LED color to notify you of standby mode. The screen also shuts. To use it, just put the portafilter in and it starts within a second.

Edit recipe , scroll down to input brew time. That’s the “manual GBS mode”. And it ask you after every shot for me with that toggled on

I went through the calibration with a 1KG weight. Out of an abundance of caution, I did the calibration 3 times back to back. And it accurately doses my target amount immediately to .1gr

There’s decent torque to it, it is not on a grinding non slip mat. It’s directly on the counter for me. And portafilter doesn’t move when grinder starts. All torque is transferred directly to the table top.

I’d join in on the good build quality! The entire case is metal. Only plastic is the buttons/knob, catch tray and hopper. I love that the burr mechanism is similarly built to their cafe level E65/E80 GBW models. Kind of a quick disconnect system. https://preview.redd.it/7xy32cl6mqeg1.jpeg?width=3024&format=pjpg&auto=webp&s=163cfe14148c16bf61aedd01d20db37ba94a31eb

Hey y'all so I got my La Marzocco Micra a few months ago, and I felt like the main limitation to my workflow has been my grinder. I ordered the Mahlokönig E64 WS around the same time I received my Micra, and the wait was worth it. Not only the grinder extremely quiet for home use, I love the high tech interface. It's quite snappy and the grind is so precise compared to the Baratza I was using before as a temporary solution. Only small nitpick on this grinder is, the load up time takes around 20-30 seconds for the OS to boot up, and additional for home use the power button should be somewhere on the front of the unit not the back. Loving this setup nevertheless.

Based on your comment I just leave it on now and that's perfect 😅 when I first got it I thought I'd have to manually turn it on and off everytime.

When I used it, it spits out the retention first, then you empty the portafilter then put it back in and it grinds. Seems to work pretty good for me.

It works great you can adjust the grind size and it does it in literally one second, you use the scroll wheel for precision. Seems to work great.

All of the top baristas I've talked to (even mentioned what I bought to some people in Florence Italy during my trip) said it's a great buy due to low retention and great quality burrs. Part of the reason I went with this over the Pico is because of retention. You can adjust the chute however you want so I'm very happy with the build quality.

I use a Breville smart grinder at work and it works great. I have a Mahlkonig at home and it works better. 

I have the Mahlkonig and am extremely happy with the results, if you’re looking for recommendations.
