bought this used from Marketplace and the previous owner was kind enough to run it through her dishwasher for me before I picked it up. this helped me get it back together properly after dismantling it and wiping everything down with iso.
I was camping and this fell apart during use into all the pieces, and I was lucky enough to recover them all in gravel, dirt, and such. I wasn't exactly sure how to reassemble, as it isn't entirely intuitive. Many thanks for the helpful guidance on how to reassemble it correctly.
So glad I've found this video! Not just for cleaning but for the setting on my grinder. I've been grinding at 5 (half turn), just rest the tamper on top and spin to level the puck. Tried your setting, tamped harder and pulled a perfect shot. Thanks 😊
fantastic video mate the bearing tip saved my ass as I realized when it popped out which way was it supposed to be placed and you helped me heaps. cheers!
Thanks for the video - was extremely helpful. Turns out my top and bottom burr were stuck together. I removed the rest of the parts so it was just those two, up-ended it (so the screw that would be where the adjuster and all is now facing the ground), held it by the top burr housing and beat it against my carpet with a few firm strikes and it dislodged. I'm now happily enjoying espresso again, thanks a lot!
I bought my jx pro about a year and a half ago. I watched this video at that time and decided it was too complicated and I really didn't want to take it apart if I didn't have to, so I have not. I use it 2 or 3 times a day. Guess I should consider cleaning it though.
At some point...probably. It's really not that bad, just make sure everything is the right way up and don't let it spring apart when you take it to pieces.
Excellent video. I do wish I'd found it before trying to re-assemble the grinder on the basis of the enclosed (inadequate) instructions and having to order replacement "sliding column" and adjustment dial. :) Thank you!
On mine, it says that the dot on the bottom side of the upper carrier has to be aligned with the red dot at the top. You did point out that the side with the dot has to be pointing down, but it can go down in 1 of 2 directions (and 1 of those directions is not correct, according to my instructions). Just thought I'd mention it.
I think something that was missed in this (very good) video is the fact that on the bottom, when you unscrew the big burr, there is an adjustable collar that allows you to move your big burr portion of the machine tighter against your small burr or less tight. If you reassemble your grinder and find it grinds more coarsely than before, you need to unscrew the big burr, and open the collar part. It is the smooth part of the lower section. It is easy to miss, because the portions are so well machined you think it is just a one piece lower body. Sorry I cannot describe it better, and hope it helps people troubleshoot their grinder.
Hey there! Thank you for posting this.. really helpful, even after half a decade!! What hand coffee grinder would you recommend as of today? I would love to hear that Cheers!

Nice video ! My grinder burrs appear to be seized, in the sense that adjusting the coarse/fine setting doesn't open the burr. And if I try to move the handle , it doesn't budge, any idea how to fix this? Thanks!
There is another portion of this grinder that can be unscrewed. It's the top portion (the part that has the red dot) from the main body. Mine started coming loose, and I accidently cross threaded it, and now I've got problems.
The only thing you can do is run a very small sharp object like a dental pick around the thread to try and straighten things out and clear the grooves...then super carefully keeping it level to the thread try to screw it on. Once it's on right, work it back and forth a few times to ensure the thread is clean and straight.
Interestingly enough, my recently purchased Jx-Pro's upper burr ring section doesn't seem to screw off. Wonder if and why they changed that, it was a nice detail.
My newer JX Pro has a removable upper burr but it took a huge amount of elbow grease to remove. First time I disassembled I thought I couldn't do it but lo and behold, a lightly wet rag got it loose the second time around.
@@stististi I feel like it should be removable. Having a non-replaceable burr piece sounds like a critical design issue for a grinder so I'd imagine that 1Zpresso would keep it so.
Got a coffee grinder with aliexpress. From 1 to 9 clicks clings with one side of the millstone. And with only 10 clicks, it scrolls without touching. Do you think this is a marriage? In my opinion, the shaft is not even! I thought from the first click there should be free rotation if everything is well centered. I haven’t ground coffee yet and hasn’t taken apart. I don't know what to do, whether to return it to the seller or not.
I couldn't see a way of doing that because you would have to know the position of the adjustment ring is correct before tightening it and I couldn't see any way that could be done. Once the grinder is burr touching point, you would have to loosen the adjustment ring completely to be able to adjust it. See assembly at point 8m 56s...
@@PavelSafronov1980 the instructions on that site are utterly terrible. Most people skip them and, if they're determined to zero out, they put the nut on and off, pushing the inner burr from the bottom to keep trying until they accidentally screw it on it the correct orientation
Good video but, I was going to complain about how you neglected to show the "Zero Adjust". I like your response to another commenter, "They're just numbers , don't lose any sleep. That is exactly what the Zpresso website states !
Well they are right...I know it's about 1.5 turns from closed (working from memory) to get to the espresso range, then about 4 seconds ish per click on/off the shot when I adjust it. keeps it uncomplicated for me.
I just tried a JX Pro and there is a tendency to unscrew the body (the part with the reverse thread) while grinding. In this video, we have to remove the inner burrs before we can unscrew the body/outer burr. My question/concern is have or will I spoil the grinder each time I accidentally unscrew the body/outer burr while grinding? Of course I quickly screwed it back... Please advise! TIA!!!
Thank you for a detailed manual! BTW sometimes I have to re-adjust the dial after grinding some coffee, is it an absolutely normal situation or should the adjustment stay the same unless you change it by yourself?
Why does my Jx pro (purchased December 2020) appear to have different internals? The adjuster looks entirely different. Purchased directly from the 1zpresso site.
@@DaveCorbey thankfully I had only just opened the box and opened your video before doing anything else. I am able to exchange it for the pro. I was so confused for a few minutes.
Dave. Great video. Just got Jx Pro. Is there a way to take away the plastic cover from the handle, so that Its open like the KINU? That way I can load beans & ajust without taking the handle off?
Great video! My JX-Pro is on the way. I take it that calibration is unnecessary. Just rotate to 0 (clockwise-fully closed) and count clicks/numbers counter-clockwise. If you remember how many numbers/clicks, just go in either direction to change your grind. Dave, when you reset yours by two turns, that would put you at 80 clicks, or about 1,000 microns, right? I don't do espresso, but isn't 1,000 a bit coarse? I brew French press, and may use a Virtuoso+ set to #16, or about 600 microns. Something seems off.
IMO, it's different micron measurement. Your 80 clicks~1000 microns is Burr gap and it doesn't predict coffee particle size reliably. If you want to correlate between those two microns, you way want to use KRUVE sifter to see the coffee particle size
Have you looked into calibrating the grinder at all (eg: to have 0 be the tightest/closed setting)? Also, Did you do any disassembly of the top carrier portion of the grinder? (The oversized ring that captures the upper bearings). My unit arrived with that portion unthreaded a bit. I tightened it in before playing with grind settings though (it's also reverse threaded like the lower carrier.
I probably could have don't but they are just numbers....it didn't matter that much to me. I know that 1.5 turns I think it was gets me in the espresso ballpark and that a click is 6 ish seconds on the shot, so I get in the ballpark then pull a shot and adjust dose for fine control (of shot time/weight) from there.
@@DaveCorbey appreciate this! Forgot i commented here lol. I ended up shooting an email to support and i needed to use a hex key. Tried about everything other than that
Hello, something really disappointing happened with my JX pro. I opened it and cleaned it exactly as per the instructions I found in the box. The big problem is that 1 full round now, gives me Turkish coffee-like grinds!!! Before with slightly less than one full round I could make espresso!! What has happened? How to solve it?
From memory I am pretty sure I had to go approx 1.5 turns from closed, to be in the espresso range. Different beans will need different grind settings e.g. A brazilian coffee needs to be ground much coarser than an El Salvador for the same flow rate in an espresso machine.
Dave Corbey thank you Dave! I understand, what I can’t understand is why, with exactly the very same coffee, before dismantling the piece 1 turn was enough, and now I need almost 2 turns! I can’t understand what I misplaced, I literally did the recommended procedure...
@@stemazzo84 Try doing it again but follow my video instructions exactly, perhaps you have a cap or washer the wrong way round or misplaced. I really did review it very carefully and took it apart quite a few times and never had a problem.
hi all, I'm worried I broke my grinder... everything seem's shoved up a little bit and I can't move anything at all. Does anyone have any ideas? In this video, the lower burr comes right out, but with mine now it is so stuck I can't seem to move anything at all... I'm distraught.
@@DaveCorbey thanks so much! I actually got it back to normal; I did a bit of loosening on that allan key slot, and the spring actually popped it out when I tried to reassemble. phew.
I never worried about it. They are just numbers. I'd close the burrs to touching then back 1.5 turns or whatever to espresso. You just note how many turns to burr touching prior to disassembly.
It is a good video, but it's missing what all the other cleaning videos are missing and that is keeping your original calibration intact, especially if you've had to zero it out.
