In order to install the washer, you do not need to disassemble the grinder. After removing the upper millstone, the lower millstone is unscrewed from the shaft clockwise. In order not to scratch the millstone, place a rag on it and turn it clockwise with pliers. This grinder has a coarse grinding step. Therefore, it will not become an espresso grinder.
Thank you very much.
Hi can you do a video on that? Thanks for sharing anyway.
@@AKMAshrafuzzamanJitu Hello. I sold KG-521, it has too coarse grind adjustment step. It is not suitable for single bottom baskets. I bought a NEMOX LUX and installed a micrometric grind adjustment screw.
Thanks a lot for your video. I've just managed to successfully tweak my grinder - let's see tomorrow morning how the grind result will look like.
Just some learnings:
1. as suggested from someone else to get access to the washers from the top: I was not able as the upper millstone was tightened too strong (but now after dis- & reassembling it's a great shortcut to do further tweaking)
2. Washer: inner diameter of 10mm is important, but the outer diameter of 15mm is not as important (I think you could also install 20-25mm easily)
3. to remove the power button I needed to cut off the 2 barbs of it (but don't worry about it). otherwise you don't get access to the screw underneath.
4. at 4:46min it's hard to see, but you need to push the "plate" down to screw the nut on the threaded rod
5. at 5:48min: start with the front and don't pinch this sealing thingy from the buttons module. really take care that the buttons are properly working (mechanical feedback). double-check or you need to reopen everything later (like I did).
have fun tuning your grinder!!
hi thanks for your notes. u mean the outer diameter is ok? I installed a outer diameter around 16mm with one Ori washer my grinder seems to get stuck with beans and not grinding at all
@@wenkf I really thought it makes no difference cause there was enough space around. but unfortunately you proofed me wrong, I guess ... I'm sorry 😔
I’ve just undone this “tuning” made by previous owner. The large gear (the one with the nut) started to slip under load - this is what springs and balls are for - to protect the motor if the mill gets stuck or something. But the problem is that with extra washer the shaft becomes too short. The shaft has certain shape and it’s important that the shaft goes through both metal sides of the large gear. I don’t think I made it clear enough, but TL/DR is that it’s not enough to just put extra/bigger washer to have reliable setup.
Thanks, I did this. Few notes:
- After this, seems all settings above 5, the top part of grinder is shaky. I did not try grinding with it since it seemed scary, and i only need espresso.
- I dont know if I fucked up, but seems after this I cannot use the portafilter mode,,,,, I will try and hack container mode, but it is not as easy to start stop in that
- The grind setting of 4 gives me incredible grinding, works well with bottomless portafilter + EC685 (Previously setting 1 was watery!)
I got 10pc washers of 1mm, 1.5mm & 2 mm. I ended up using 1.5mm + One of the old (seems 0.5mm?) for total 2mm, seems good on first try.
what is the outer diameter? I think I got a outer diameter too big. and the thickness is 1.5mm. but my grinder got stuck with beans it cannot grind at all.
I put only 1,5mm washer and on grinding 1 got a perfekt grind.
so you only changed one washer into a thicker one? I thought there were two washers in that place, will it be better if I change them both?
Great video, this. This modification will make the grinder suitable for non-pressurized filters?
Would really like to know this aswell.

When removing the grinder axle, be very careful moving the motor unit, mine dislocated 6 springs 6 steel balls and a washer so I had to open the compartment and fix it...
Здравствуйте, а какой все таки из способов лучше для модификации?? У вас просто два видео на канале. И хотелось бы знать какой эффективнее и безопаснее??
After modification, you are still using a pressurized filter basket. will this change the grind enough to use a bottomless filter basket? can you send a link to where i can get the cup you are using?
All of a sudden my Delonghi grinder grinds a really rough batch of coffee, even on the finest setting. It's only a few months old
Any idea what could cause this?
Additionally, could you please make a video showing how to replace the milk frother?
Are you talking about the steam wand? There was a video that well known by now, search delonghi rancilio silvia.
Hey Mate, where did you find a dose cup that suits the 51mm portafilter?? Cheers.
I bought it from ebay, it's a 2 oz stainless steel cup.
@@ArtyHome is it possible to share link from ebay or amazon ? I also want to ask where did you get it :) by the way after your amazing videos i order delonghi ec685 and kg521 grinder 🤤
How to open the top cover? I find it so difficult.
Use 2 washer or 1 washer?
My Motor burned, that was too much. I did this optimization from 1mm to 1.5mm. And after straight 10 cubs the engine went even slower and warmer. So setting 3 with 1.5mm copper washer is to close and too hard work for the engine. So LOOK OUT!
i think me too 😢 do you have fix the issue ?
@@sizzlarrmaybe a polished stainless steel washer ( in german called Passscheibe) that adds around 0,25-0,5mm thickness should work well. It‘s important to use a washer material that doesn‘t add to much friction to the assembly. It‘s also important that after modification you start testing with a coarse to fine setting and not start from the finest setting to avoid direct contact of the milling parts
I was luckier as in my case the big gear with springs and balls started to slip after a minute of constant grinding.
Hi, are you adding another washer (together two washers) there or changing the existing one for a new thicker? Thank you
Put one old one and add another one up to 1.5mm thick.
Hi, nice video!!
Can you do another video with unpresured portafilter I want see if is good extraction 😉😉😉
I will do it next time. Stay tuned, thank you.
That's just what I need. Thank you for sharing this！
You're welcome 😊
Thanks so much
Thanks for the tips. When you say thickness is 1.5mm, you mean for the new or the old one ?
New, 1.5mm thick, but I think the thickness may be different on each machine. You may need to adjust more than 1 time.
So you have experiment with different thickness and found the optimum is 1.5mm thickness ? How about 2mm? Great video btw, have been looking for this for 2 years ! I also have EC685 and KG521 like you, modified the steam wand, but the grind is too course for non pressurized.
You can give it a try. Someone suggested an easier way to do it. " order to install the washer, you do not need to disassemble the grinder. After removing the upper millstone, the lower millstone is unscrewed from the shaft clockwise. In order not to scratch the millstone, place a rag on it and turn it clockwise with pliers."
Hello, what is the outer diameter? where to buy it?
15-20 mm. you can use.
can I add 2 washers at the same time to obtain a finer grind ?
The thickness might be too much. I recommend trying one piece at a time. 10mm Copper Washer - Oil Seal Sump Washer is an available option. www.ebay.com/itm/4mm-5mm-6mm-7mm-8mm-9mm-10mm-Copper-Sealing-Washer-Oil-Seal-Sump-Washer/284105929710?hash=item42260873ee:g:eLUAAOSw3Zpf66g0
@@ArtyHome I inserted a single 10 mm washer, but I did not have the right result for the espresso, I still need a finer grind, what i do ?
@@ayoubjaddad5756 You have to try to increase the thickness of the washer. But if it is too thick, it cannot be crushed. Someone suggested an easier way to remove the gear, try this. "In order to install the washing machine, you do not need to disassemble the grinder. After the top mill is removed, the lower mill is unscrewed from the shaft clockwise to avoid scratching, place a rag and turn it accordingly. Clockwise with pliers. "
@@ArtyHome i don't understand can you explain to me more and more or with a video please? I'm disappointed with the grind
@@-.-._.-.-._. i had same problem, you are not going to find it on the internet, you have to buy it from the drugstore, you put 2 washers of 1 mm
mine is block now 😢 i have no idea why 😕
the teeth of one of the motor wheels have broken so that the wheel no longer turns and therefore the crusher no longer works.
How to remove power button
I’m stuck here too...
Push the button out of the casing with moderate pressure from inside the grinder. Should pop out easily enough, those snap fits on each side don't need to be squeezed inwards to get it out.
It should pop back in easy too with some pressure
Sadly I have not managed to get the grind fine enough and have sent the item back for a refund. The search continues.
J'ai pas compris la vidéo ?????
Pourquoi une rondelles de 1.5mm???
Pour rehausser la "lame"basse afin d'obtenir une mouture plus fine
Keep interrupting 👍🏼❤️.
Before Shot looks better than the After mod. shot.
Just don’t do this. Try to sell it. If you want Espresso you will have no fun … even with this hack. The results are far from execrable.
I know good results do have their costs … but for espresso 100 bucks on top to get a real one.
what do you recommend?
Every Eureka Mignon is able to create Espresso. Also the cheaper option are in another level.
In order to install the washer, you do not need to disassemble the grinder. After removing the upper millstone, the lower millstone is unscrewed from the shaft clockwise. In order not to scratch the millstone, place a rag on it and turn it clockwise with pliers. This grinder has a coarse grinding step. Therefore, it will not become an espresso grinder.
It's a really easy way. Thank you very much.
If you just disassemble the upper mill, the nut and the washers on the other side will fall into the machine, which will be impossible to put back.
@@puzhao1639 Perhaps, but my shaft is tight and did not try to fall. Maybe the seat in your mill is already worn out?
Could you elaborate on this? I'm very interested.
I don't have a long screw driver, so I have removed beans holder, and the upper millstone, however I cant seem to spin the lower millstone. It doesnt budge at all.
I have tried using a rag but I can't get a solid grip on it.
Also, If I am able to spin the lower millstone enough, will the current nut fall into the machine?
@@mnmldev8636
It will not work to unscrew the lower millstone with your hands. On top of the rag, you need to firmly grasp with pliers and sharply, with force, turn clockwise. The millstone must break loose. Further, it should be easily unscrewed by hand. If you are afraid that the shaft will fall down, do not unscrew the millstone completely. Prepare the washer in advance and perform all further actions with your right hand, and with your left hold the shaft from falling down. Good luck.
