I was having issues with my expressos just extracting too quick and suspected the grinder was the culprit. I have this grinder and wanted to try the mod to see if I could get better expressos. Unfortunately I didn't have any spare washer but I used (dont shoot me) a PAPER washer cut to the appropriate size. It worked well and I'm getting now incredible crema like I've never seen before. I know its a very temporary fix, but now that I know it works, I'll get a proper washer. The difference is just INCREDIBLE. Thanks for the video.
I did this mod. Thank you!!! Worked great. I ended up only using 1 copper washer, and 1 original washer. The motor frooze when I tried 2 copper washers. Just a tip if anyone else runs into the same problem.
Exactly the same for me. 1 original and 1 copper 1mm ended up being perfect. On grind setting 1 after the modification I have been able to produce fine enough grounds for genuine delicious espresso with a single walled basket.
I also did the hack. I used 1*original and 1*1mm so total is 1.5mm. I ground in setting 1. I hear a metal noise but I don't think it's a big stress for the grinder. Time will show the outcome :P. Thanks for the video!
I strongly don't recommend people to follow the modification in this video. This could cause seriously damage to your machine. I'll try to explain why. I followed the steps in this video to unscrewed the burr at the top and put it back on. At a moment, I thought it worked, but shortly the burr just stopped but I could still hear the motor was still running. I was wondering whether the coffee bean stuck at the burr and caused blocked. Then, I left no choice but to open up the machine completely like the steps in the other video and checks out all the unit inside. The motor looked fine and somehow the burr was running again. After a while the burr just stopped but the motor was still on. I decided to open up the motor as well. When I dissected the motor unit, I found that one of the gear inside was broken. That gear was directly linked to the motion of the burr. The problem is, the gear running the burr underneath is a metal unit, but the gear inside the motor unit is made of plastic. So, when you brute force the burr by unscrewing (or even put it back on) as per the video, the force could shear off the spike of the plastic gear of the motor unit by the metal gear of the burr, i.e. a flat plastic gear just wouldn't turn other parts at a point. This is also the reason why the video mentioned it needs to unscrew with a force, and why it looks the burr is locked. That's because the gear underneath was tightly together. Yet, metal parts could tear down the plastic when you apply a force on it at a reverse direction. Now, I could do nothing but to throw this broken machine away. I tried to look up a replacement for the motor unit, it cost almost like more than half of the machine and not really easy to find. All in all, if you want modify your grinder, you'd better to open it up at the bottom, making all the way up to the burr.
A similar modification is being made for the graef cm702 and has very effective results. This model looks very elegant and I came across your video while researching if this modification can be done. The good news is that it can be done!
Advice for those struggling to unscrew the blade: I used folded paper, something lightweight like newspaper, but I folded it many times for better grip. If you don't fold enough, the blades will cut through the paper. As a female with limited strength, it took me a while to try, but it eventually worked. Good luck everyone.
EDIT: I have tried this and it seems my lower grindstone/burr is either too tight or too loose for this operation at 4:00 to work. After attempting to loosen the burr from above, all that happens when I turn it is it rotates whole thing. Rather than loosen it, I just wind up spinning the motor, so in the end I had to disassemble the thing from the bottom up. Much more work, though it's manageable. What a beautifully simple mod! Push the lower Burr just a hair higher than it was before with a washer. Thanks for posting this with such clarity and detail. Pro-tip: watch this at 1.5X speed.
I recently bought a used Delonghi KG520 precisely for the purpose of trying to carry out this update, and in reality what I've read in some comments happened to me: I couldn't fit the two copper washers, I could only fit 1 plus the original one, but the result was positive. What happened with the two copper washers was that the motor spun on its own and wouldn't hold the grinding wheel. I tried one more time to fit a copper washer and the two original ones, but the same error still occurred. So it only worked with the 1 copper washer plus one original washer.
Thank you for the tutorial, and also from other people. I ended up using one 1.2mm thick and one washer with the #2 setting. The #1 setting for me sounds like the grinder is struggling. It was fine enough for me, a lot finer than #1 stock. Thanks again. You saved me a lot of money. Was going to buy the Breville Smart pro.

So long as you have something that is 10mm diameter and not so big outer diameter it should be fine. So, I went to a nearby hardware store. I followed this video exactly, removed the 2 small washers, put 1x of my own and put back only 1 of the small washers out of the 2 from before. I think you should experiment as well. Just be gentle with the machine and remember how it was placed before. Good luck!
Hello! I just finished mine. It puts a lot of strain on the machine. I tried a washer + a factory one but it's still tight. I finally put the two thicker ones back on and it's still straining. Also coffee does not have any amazing effect. I'm very afraid that apart from the grater, the pipes of the coffee machine will also be strained, so I say to end up with a factory setting.
Mine works with 2 washers 10mm and 1 original washer to get to the finer grind ^^ and I broke the paddle wheal bc I used the wrong typed of pliers when I tried to unscrew the gear XDDD I had to have it 3D printed because Delonghi doesn't sell that parts =.= really thank for your tutorials!!

@@brendan4663 There's another method where you need to disassemble the whole grinder from the bottom. This is a lot more tedious (and you need a humongous screwdriver), but eventually it worked for me. Even though I seem to have somehow messed up the grind setting ring assembly a bit. It's harder to turn that before, but it still works.
@ArtyHome Is there a difference between KG521 and KG521M? I tried these instructions with KG521M, and when I turned clockwise, the burr was not locked as in your video.
Just did this mod. Grinds like babypowder. Makes a big difference when using a non pressurised Portafilter. One question. When tightening the burr back on, I only tightened it till the motor gave resistance. Obviously I couldn’t tighten it further. I assume that’s enough
Hi, thank you for your amazing videos and valuable information! I just got the Dedica Barista Set and want to modify my grinder. Should I get a washer with 1mm thickness or 0.5mm thickness? Thank you for your help!
Finally got around to doing this mod. Until I receive my non pressurized basket I am using a trick with my pressurized basket into accepting very fine grind by putting a little bit of courser grind in the bottom. Works like a charm! Definitely got more out of the dedica.
My burr was way too tight, I couldn’t budge it So I came up with a simple solution. I filed about a millimetre off the lugs that rest on the rail. My grind is now fine enough, and works very well with my Bellman too.
One thing i observed, the default grinder setting "1" of Dedica suites to pressurized basket of EC685, for non-pressurized basket then it will be more watery and lesser time even you tamped it to the highest level.
Great vids.... Are you showing 2 ways to do the mod or is it different for the KG521 and the KG521M? Also, why would i want to use the container mode with the filter holder?
Always a pleasure watching your videos. On your previous video regarding modifying the KG521 M Grinder for a finer grind last Oct. 30, 2020., is today's video an easier way to modify the KG 521? @Arty Home
I was able to unscrew the burr very easily using a short length (about 20cm) of PVC drain pipe 32 mm od, 28 mm id. The burr bit into the soft plastic pipe so I was able to get a good grip without using tools. Using the pipe also eliminated the risk of damaging the burr. After removing the burr, I cleaned it using a stiff brush to remove small fragments of PVC.
Thank your video, KG521 is make me crazy, I can’t use it to make a great coffe. Is the thickness of two new rings 1.5mm? Or each new ring 1.5mm? Expect your answer. Thank you very much!
Interesting, but I'm not sure that the protective felt seal is still in contact with thicker washers. A gap will be a problem. What about it one year later ?
Thanks for the tutorial! I been looking forward to proper tutorial on how to modify my KG521 for awhile. Since there are no narrative to explain each step, so I have some questions here: (1) are you replace both of the ring inside the machine with oil slump washer ring?; (2) Understood the inner diameter of the washer ring is 10mm, however the whole diameter of the ring? Or any ring with 10mm inner diameter will do? (3) Is the thickness of the ring preferably at ~1.5mm as mentioned on your last tutorial? (4) is there any material specific for the ring? Thanks in advance and wanna let u know, I enjoy watching your video
Thank you very much for watching the video. I will try to answer But i'm not good at english 1. Use 2 washers. 2.This washer is the same size as the original, it works. 3.Yes, it's about 1.5mm thick. 4. Should be metal or brass.
Thank you for the video, i tried it by myself and wasn't happy about the result, i noticed that if you are putting washers under the grinder, you reduce the axial play of the shaft and you increase the friction wich leads to heat and in the long term you damage the motor. To avoid that, you need to put another washer with 10mm outer diameter an 8mm inner diameter and the same thickness as the other washer on the shaft under the thread, so the axial play keeps the same. The grinder is higher an you can grind finer. I hope i could help.
Hi again @Ilias, you mean using only an extra washer (1.5mm or 0,5mm) between plastic piece and metal thread? or.. using the 2 replacement washer (1.5mm) that the video says + another one (0,5mm or 1,5mm) like previous option? so.. only one vs two replace + another extra.. And finally, the extra one that you says it is of 0,5mm or 1,5mm Thanks again man
@@themidnightlord Hey, you need to put a washer between the shaft and the thread. The washer is no standard size you need to make that by your own. It should fit into the grinder and over the thread but not over the bigger shaft after the thread. I hope you understand what i mean.
Great vid! Very relaxed pace, but at least we get to see everything! I'm sure DeLonghi chose to use these thin washers (and get worse espresso results) for a reason. Do you know if there is any downside to this mod? Like lifespan or temperature etc?
I think it’s just the same reason that most passenger cars aren’t tuned to have the most precise ride, it’s a trade off between the different ends of what a consumer will find useful. The loss with this modification is that your coarsest possible grind won’t be as coarse as before. Equally, they could expand the range of this thing, but then you wouldn’t have the same small step sizes and you’d lose precision in adjustment.
When using this grinder and putting in the measured amount of beans, you may have to press grind multiple times in order the grind everything out. By using container mode, you can press it once and keep it going for a longer amount of time.
For me, this method didn't worked. Unfortunately i cannot remove the grind with the patent. It spins but it does not scroll. Is there any tips for that, or i should disamble everything? Thanks a lot.
Hi, I couldn't find the washer with the same outside diameter at any of the hardware stores in Melbourne. Can you please share the exact size of the washers you used so I can search online? Also what material are they made of?
Cheers. Will try the mod this weekend. Just too coarse for me. By the way, what are you using to grind the coffee into. Seems like it further limits wastage. Cheers EJ
Hi! Thank you for the instructions. I watched your previous KG521 mod last year. You put M10x1,5mm steel washer to the bottom of the head, under the nut in that video. Is this new double copper washer mod done with or without the previous mod? I mean, is this one made for making the grind even finer or are both methods working equally? If not equally, which one do you recommend?
Hi. I’m afraid to do the modification on my own as I really don’t know how to do it properly even while watching. I might damage the grinder. Does this mean if i didnt modify the Delonghi grinder, i won’t get the correct fine grind of the bean? Thank you in advance.
@@ArtyHome Thanks for your response. I’m planning to buy a coffee grinder as I already have the Delonghi Dedica. Have you heard about reviews of Smeg grinder or Breville? Not sure what to buy 😢
@@ayahdetera1653 breville is a great home machine,if you really love perfect espresso maybe better to get one with built in grinder and unpressurized filter it will do much better than modification dedica and look much better too
@@eldabasa Hi there, I’m deciding which grinder to get....Sage (or breville) smart grinder pro vs delonghi grinder? Both are similar in price (I’m in the UK). I would think both machines would require some kind of modifications for espresso grind size?

I just bought this machine, Can someone tell me what the point of that mod was? To get full grind of all weighed beans and finer grind? Using less beans for same strength? As standard I used this on grind setting 2 and got a decent cup of coffee with creama, perhaps if the burr grinder is worn after lots of use I could understand the burr mod. I’ve only just starting using it, so maybe it will make more sense later on, but I should say it’s so much better than my old £50 quid Delonghi burr grinder.
Original washer's diameters : Outer : 14mm Inner : 10 mm Thickness : 0.5 mm I prefer 2 x (15mm x 10mm x 0.7 mm) washer. I've been using it with modified washers about 4 month. No problem, no damage and no burr friction. ( I tryed with 2 x 1 mm thickness washers and 0.7 mm + 1.0 mm thickness washers both have burr friction noise. Be careful )
@@UgurSabuncu Can I ask where you found the washers that you are using? It is very tough to find such washers with these specific dimensions! Also, are you using two of the replacement washers? So two .7mm thick washers? or one .5mm and one .7mm? Much appreciated for the measurements
@@Damascus65 In local hardware store. I seach and visit couple of them and finally find it. First i try 1 x 0.5 mm (Original washer ) + 1 x 0.7 mm then i try 2 x 0.7 mm. I get better result with 2 x 0.7 mm and still using these setup with no problem about + 4 month.
@@UgurSabuncu Just an FYI -- I found my solution... What I looked for is "round shims," not washers. Shims are measured by thickness and thus easier to find for specific widths. I used 4 shims that are 15mm OD x 10mm ID x .125mm thickness (in addition to the existing 2 washers that are already on the grinder) and now the grinder is clearly producing a much finer product. The total thickness of the 2 washers + the 4 shims is 1.5mm. I can tell this based on how 14 grams of grinds on the finest setting without the shims look and behave on a piece of white printer paper versus 14 grams of grinds on the finest setting WITH the 4 shims. Those ground with the shims added are clearly much finer and behave like ultrafine sawdust compared to sand. I would also say that under flat white light that the finer grinds look a bit different color wise and are more of a tan brown than a dark brown -- so there is a visual difference that gives me an indicator that they truly are finer, as well. I first tested 5 of the shims (in addition to the existing 2 washers that are already on the grinder) for a thickness of .625mm (shims only) and the grinder would not grind my beans and kept locking up. Therefore, I removed 1 for a thickness of .5mm (shims only). It works perfectly now. Here are the shims I purchased - www.amazon.com/gp/product/B0036R4RO4/ref=ppx_yo_dt_b_asin_title_o00_s00?ie=UTF8&psc=1 I also wanted shims that were not copper, as copper is a far softer metal and wears faster than stainless. As well, I wanted 304 stainless if I could find it, as it is far stronger and more corrosion resistant (mind you, these are only .125mm thick so I do not want them to wear over time). I do not believe these are 304 stainless, as the Amazon listing and the product bag they came in do not say such. They are listed as 302 I believe, which is just fine and is corrosion and wear resistant. I then brewed a double shot in a bottomless portafilter with the regular grinds. The shot came out messy and the machine was spraying espresso a bit all over the counter. There was not a thick crema. I then brewed a double shot in a bottom portafiler with the finer grinds. The shot was still a tiny bit messy, but less messy compared to the prior double shot and there was a much thicker crema. Admittedly, this difference could have come down to my lack of expertise in leveling, distributing, and tamping the grinds. However, I don't think that is the case and I think that there truly was a better result with the new, presumably finer, grinds.
@@Damascus65 Hi there, so basically the optimal total thickness is 1.5mm? I found this online: www.accu.co.uk/en/shim-washers/62786-HSHN-10-16-0-5-A2?uk_google_shopping=1&c=3&gclid=EAIaIQobChMIyZyg_5Xo7wIV0O3tCh3AXguBEAQYASABEgJZIfD_BwE
Maybe close the gap between upper n inner burr...so the burr together becomes close and its grind finer..its just my thoughts,dont know correct or not.

@@brendan4663 There's another method where you need to disassemble the whole grinder from the bottom. This is a lot more tedious (and you need a humongous screwdriver), but eventually it worked for me. Even though I seem to have somehow messed up the grind setting ring assembly a bit. It's harder to turn that before, but it still works.
Thank. I am pleased to follow your work. Good luck.
Thanks and welcome
@ArtyHome Is there a difference between KG521 and KG521M? I tried these instructions with KG521M, and when I turned clockwise, the burr was not locked as in your video.
Excellent video, great quality, a question, will the kg520 model (without screen) be the same procedure?
Just did this mod. Grinds like babypowder. Makes a big difference when using a non pressurised Portafilter.
One question. When tightening the burr back on, I only tightened it till the motor gave resistance. Obviously I couldn’t tighten it further. I assume that’s enough
Thanks for the video. Kan it also work with KG520?
Hi, thank you for your amazing videos and valuable information! I just got the Dedica Barista Set and want to modify my grinder.
Should I get a washer with 1mm thickness or 0.5mm thickness?
Thank you for your help!
what mean u glue the holder?
Finally got around to doing this mod. Until I receive my non pressurized basket I am using a trick with my pressurized basket into accepting very fine grind by putting a little bit of courser grind in the bottom. Works like a charm! Definitely got more out of the dedica.
Thanks for sharing.🙂
My burr was way too tight, I couldn’t budge it So I came up with a simple solution.
I filed about a millimetre off the lugs that rest on the rail.
My grind is now fine enough, and works very well with my Bellman too.
Filed with what?
One thing i observed, the default grinder setting "1" of Dedica suites to pressurized basket of EC685, for non-pressurized basket then it will be more watery and lesser time even you tamped it to the highest level.
Great vids.... Are you showing 2 ways to do the mod or is it different for the KG521 and the KG521M? Also, why would i want to use the container mode with the filter holder?
I can't turn the grinder with pliers. What should I do.
Thank you so much for the video. Do you also have a video on how to modify the portafilter that you used here using a different basket? Thanks
Does it have to be copper? It's a little rare where I am. Will a stainless washer does the same (of course with the same measurement)?
I try this and now the motor is stuttering. And I can't unlock anymore.. Any other good cheep grinder for Espresso (Cappuccino) to suggest?
I have one Smeg grinder with the same problem, I will do it the modification, thank you

Any tips on how you unscrew the burr? Because i cant unscrew it, it just rotates with the motor everytime i try to unscrew it clockwise
Is this machine work with out the container cup because I lost my
Always a pleasure watching your videos. On your previous video regarding modifying the KG521 M Grinder for a finer grind last Oct. 30, 2020., is today's video an easier way to modify the KG 521? @Arty Home
Easier, but be careful, pliers can damage the gears.
From your video it looks easy to remove the burr but I can not seem to un-screw it.
If you can't fry because it's too tight You may need to follow this link. th-cam.com/video/f7W_PotnMsk/w-d-xo.html
Grip deeper with cloth, clockwise
I was able to unscrew the burr very easily using a short length (about 20cm) of PVC drain pipe 32 mm od, 28 mm id. The burr bit into the soft plastic pipe so I was able to get a good grip without using tools. Using the pipe also eliminated the risk of damaging the burr. After removing the burr, I cleaned it using a stiff brush to remove small fragments of PVC.
Thanks, guys, I got it mod finally.
Thank your video, KG521 is make me crazy, I can’t use it to make a great coffe. Is the thickness of two new rings 1.5mm? Or each new ring 1.5mm? Expect your answer. Thank you very much!
Interesting, but I'm not sure that the protective felt seal is still in contact with thicker washers.
A gap will be a problem.
What about it one year later ?
Thanks for the tutorial! I been looking forward to proper tutorial on how to modify my KG521 for awhile. Since there are no narrative to explain each step, so I have some questions here: (1) are you replace both of the ring inside the machine with oil slump washer ring?; (2) Understood the inner diameter of the washer ring is 10mm, however the whole diameter of the ring? Or any ring with 10mm inner diameter will do? (3) Is the thickness of the ring preferably at ~1.5mm as mentioned on your last tutorial? (4) is there any material specific for the ring?
Thanks in advance and wanna let u know, I enjoy watching your video
Thank you very much for watching the video. I will try to answer But i'm not good at english
1. Use 2 washers.
2.This washer is the same size as the original, it works.
3.Yes, it's about 1.5mm thick.
4. Should be metal or brass.
@@ArtyHome Thanks for your answer! Will give it a try definitely :D
Did it work with you ?? Please reply as I will give it a try😃
hi, i followed exactly to change washer only but its not grinding. the grinder blade not moving
Hi 👋 what size for grind size normaly for v.60.thank you.
Thank you for the video, i tried it by myself and wasn't happy about the result, i noticed that if you are putting washers under the grinder, you reduce the axial play of the shaft and you increase the friction wich leads to heat and in the long term you damage the motor. To avoid that, you need to put another washer with 10mm outer diameter an 8mm inner diameter and the same thickness as the other washer on the shaft under the thread, so the axial play keeps the same. The grinder is higher an you can grind finer. I hope i could help.
True, i figured out the same
Hi @Ilias, thanks for this tip, Could we chat? I really appreciate some more details about it.. Regards
Hi again @Ilias, you mean using only an extra washer (1.5mm or 0,5mm) between plastic piece and metal thread? or.. using the 2 replacement washer (1.5mm) that the video says + another one (0,5mm or 1,5mm) like previous option? so.. only one vs two replace + another extra..
And finally, the extra one that you says it is of 0,5mm or 1,5mm
Thanks again man
@@themidnightlord
Hey, you need to put a washer between the shaft and the thread. The washer is no standard size you need to make that by your own. It should fit into the grinder and over the thread but not over the bigger shaft after the thread. I hope you understand what i mean.
@@ilias941 Hi, yeah!! but in total is:
a) 2 replacement washer + 1 extra washer
b) only 1 extra washer (keeping the 2 originals)?
Any opinion about this to use a naked portafilter? is enough fine grinding?
why filter holder needs modyfication in the first place?
Great vid! Very relaxed pace, but at least we get to see everything! I'm sure DeLonghi chose to use these thin washers (and get worse espresso results) for a reason. Do you know if there is any downside to this mod? Like lifespan or temperature etc?
I think it’s just the same reason that most passenger cars aren’t tuned to have the most precise ride, it’s a trade off between the different ends of what a consumer will find useful. The loss with this modification is that your coarsest possible grind won’t be as coarse as before. Equally, they could expand the range of this thing, but then you wouldn’t have the same small step sizes and you’d lose precision in adjustment.
is it the same grinder that you modify back in 2020 , i watch your youtube how to modify this grinder before
What is the advantage of using it in container mode?
When using this grinder and putting in the measured amount of beans, you may have to press grind multiple times in order the grind everything out.
By using container mode, you can press it once and keep it going for a longer amount of time.
Pls help me to know were can i buy that washer to improve my grinder too..
Great video! Can you tell me where you got this 18g basket from?
did you make modifications on your espresso machine? if so did you modify the pressure of the group head?
Hello thank you for the perfect video.
Can you give me the size of the ring cause I want to do the modification just like you?
For me, this method didn't worked. Unfortunately i cannot remove the grind with the patent. It spins but it does not scroll. Is there any tips for that, or i should disamble everything? Thanks a lot.
Hi, I couldn't find the washer with the same outside diameter at any of the hardware stores in Melbourne. Can you please share the exact size of the washers you used so I can search online? Also what material are they made of?
Cheers. Will try the mod this weekend. Just too coarse for me.
By the way, what are you using to grind the coffee into. Seems like it further limits wastage.
Cheers EJ
😂😂😂😂when i saw first pliers, i go "no no no no"!😅
When I put port-filter the grinder not recognizingit , why
Genial mucha gracias 🥰😍
I'm having a hard time gripping the burr even with the towel and pliers 😢
with me the crankshaft rotates with what can i do
when i tried to undo the bottom burr the motor just turns backwards, no way to unscrew it.
Hi why do you have to use containter mode?
what did you do with container mode? and why?
I tried this but couldn’t get the inner burr to unscrew, any ideas?
me too....
Can someone explain what the point of he “container mode mod” is please ?
Where do I get those 2 Cooper washers
what is the thickness of each of the new washer ?
1.8mm
@@seaneckhart9914 each?
is it possible to use this guide for KG521M?
Hi! Thank you for the instructions. I watched your previous KG521 mod last year. You put M10x1,5mm steel washer to the bottom of the head, under the nut in that video. Is this new double copper washer mod done with or without the previous mod? I mean, is this one made for making the grind even finer or are both methods working equally? If not equally, which one do you recommend?
Also, could someone tell me what the "Light Normal Strong" setting is for? Its like nowhere on the manual .Thanks
At what number do you grind ?
did you use 2 Screw Bolt?
Hi. I’m afraid to do the modification on my own as I really don’t know how to do it properly even while watching. I might damage the grinder. Does this mean if i didnt modify the Delonghi grinder, i won’t get the correct fine grind of the bean? Thank you in advance.
This model may not be a good match for Espresso, but for pour over or moka pot.🙂
@@ArtyHome Thanks for your response. I’m planning to buy a coffee grinder as I already have the Delonghi Dedica. Have you heard about reviews of Smeg grinder or Breville? Not sure what to buy 😢
@@ayahdetera1653 breville is a great home machine,if you really love perfect espresso maybe better to get one with built in grinder and unpressurized filter it will do much better than modification dedica and look much better too
@@eldabasa Hi there, I’m deciding which grinder to get....Sage (or breville) smart grinder pro vs delonghi grinder? Both are similar in price (I’m in the UK). I would think both machines would require some kind of modifications for espresso grind size?
@@yvonnefok163 delonghi not giving very much option for finer grind specially for using With unpressurized basket ,but with some user modification it can grind finer, i use 1zpresso hand manual grinder with it you can find exactly the grind work best with any machine but its manual, i didnt use sage so i cant tell
I just bought this machine, Can someone tell me what the point of that mod was?
To get full grind of all weighed beans and finer grind? Using less beans for same strength?
As standard I used this on grind setting 2 and got a decent cup of coffee with creama, perhaps if the burr grinder is worn after lots of use I could understand the burr mod.
I’ve only just starting using it, so maybe it will make more sense later on, but I should say it’s so much better than my old £50 quid Delonghi burr grinder.
What size washer did you replace it with?
Original washer's diameters :
Outer : 14mm Inner : 10 mm
Thickness : 0.5 mm
I prefer 2 x (15mm x 10mm x 0.7 mm) washer.
I've been using it with modified washers about 4 month. No problem, no damage and no burr friction. ( I tryed with 2 x 1 mm thickness washers and 0.7 mm + 1.0 mm thickness washers both have burr friction noise. Be careful )
@@UgurSabuncu Can I ask where you found the washers that you are using? It is very tough to find such washers with these specific dimensions! Also, are you using two of the replacement washers? So two .7mm thick washers? or one .5mm and one .7mm? Much appreciated for the measurements
@@Damascus65 In local hardware store. I seach and visit couple of them and finally find it. First i try 1 x 0.5 mm (Original washer ) + 1 x 0.7 mm then i try 2 x 0.7 mm. I get better result with 2 x 0.7 mm and still using these setup with no problem about + 4 month.
@@UgurSabuncu Just an FYI -- I found my solution... What I looked for is "round shims," not washers. Shims are measured by thickness and thus easier to find for specific widths.
I used 4 shims that are 15mm OD x 10mm ID x .125mm thickness (in addition to the existing 2 washers that are already on the grinder) and now the grinder is clearly producing a much finer product. The total thickness of the 2 washers + the 4 shims is 1.5mm.
I can tell this based on how 14 grams of grinds on the finest setting without the shims look and behave on a piece of white printer paper versus 14 grams of grinds on the finest setting WITH the 4 shims. Those ground with the shims added are clearly much finer and behave like ultrafine sawdust compared to sand. I would also say that under flat white light that the finer grinds look a bit different color wise and are more of a tan brown than a dark brown -- so there is a visual difference that gives me an indicator that they truly are finer, as well.
I first tested 5 of the shims (in addition to the existing 2 washers that are already on the grinder) for a thickness of .625mm (shims only) and the grinder would not grind my beans and kept locking up. Therefore, I removed 1 for a thickness of .5mm (shims only). It works perfectly now.
Here are the shims I purchased - www.amazon.com/gp/product/B0036R4RO4/ref=ppx_yo_dt_b_asin_title_o00_s00?ie=UTF8&psc=1
I also wanted shims that were not copper, as copper is a far softer metal and wears faster than stainless. As well, I wanted 304 stainless if I could find it, as it is far stronger and more corrosion resistant (mind you, these are only .125mm thick so I do not want them to wear over time). I do not believe these are 304 stainless, as the Amazon listing and the product bag they came in do not say such. They are listed as 302 I believe, which is just fine and is corrosion and wear resistant.
I then brewed a double shot in a bottomless portafilter with the regular grinds. The shot came out messy and the machine was spraying espresso a bit all over the counter. There was not a thick crema.
I then brewed a double shot in a bottom portafiler with the finer grinds. The shot was still a tiny bit messy, but less messy compared to the prior double shot and there was a much thicker crema.
Admittedly, this difference could have come down to my lack of expertise in leveling, distributing, and tamping the grinds. However, I don't think that is the case and I think that there truly was a better result with the new, presumably finer, grinds.
@@Damascus65 Hi there, so basically the optimal total thickness is 1.5mm? I found this online: www.accu.co.uk/en/shim-washers/62786-HSHN-10-16-0-5-A2?uk_google_shopping=1&c=3&gclid=EAIaIQobChMIyZyg_5Xo7wIV0O3tCh3AXguBEAQYASABEgJZIfD_BwE
Why by changing the washer it can make it finer? What does washer do?
Maybe close the gap between upper n inner burr...so the burr together becomes close and its grind finer..its just my thoughts,dont know correct or not.
So with this mod, does it grind fine enough for espresso (in an unpressurized basket)?
Yes.
Muchas gracias!!
