    Update - my BCG800 (which was actually 23 months old) has been replaced under warranty. Credit where it's due to Breville customer service. They were responsive and helpful by phone and email.

    I now have a BCG820, and a new problem with the grind not being fine enough..... Will comment on that over at the BCG820 forum.

    No I didn't keep the shim kit - and now I'm kicking myself !! To be honest, I didn't think of it - and besides, I didn't think I'd need it. When they released the BCG820, KatBrazier from Breville was quoted on this site as saying "no more shim kits"....

    I'm rapidly coming to the conclusion that this 820 that I got as a replacement for the 800 will just be a fill-in machine while I make plans to upgrade. Based on what I've read here and elsewhere, a K3 is looking good...

    Just got this grinder a weeks ago and love it. Have it paired with the BES920 dual boiler and works a treat.

    I was using up my BCG 800 when it turns out there is a very small stone among the beans. I stopped it immediately and cleaned it (the upper and lower burr) but it hasn't been working. It just made a rackety noise followed by a whirring sound.

    How can I open it further to see if a piece of the stone is still in the unit?

    I'm based in Jakarta so there is no service centre I can bring it to.

    **WARNING** ensure your grinder is NOT connected to a power source.

    Here is a copy of the manual for you to read before considering "surgery"
    https://www.breville.com.au/media/me...513/BCG800.pdf

    I am also confident others will come along and give you assistance.
    I myself have opened this machine up (under supervision).
    Grinder still works!
    Good Luck

    Thanks, @GreenBeanGenii

    I have tried to clean it as much as I can according to the manual. Still no love

    So did you start from the four screws at the bottom of the unit? I can't see any other screws other than those ones

    I got one of these 4 months ago 2nd hand. Was 2 years old already. Not sure if shim kit is installed or not as haven't checked.

    Problem I have is clumping. Mostly on the higher grind settings to use for my double shot on EM6910 basket.
    The Breville people keep saying its damp - my coffee was too new when I put it in there which I feel is not true.
    Anyone know exactly why it might clump and if possible to fix?

    My grinder seems to have recently developed an issue mentioned by a few folks in this thread. Basically it can't go fine enough, regardless of setting, and adding an extra 1mm shim didn't really help.

    Got a coffee machine technician to perform surgery on my BCG800. Turns out one of the gears is busted



    So yeah, unless the gear is available as spare part, I guess I have to say goodbye to my SG

    It's not, however the BES860 and BES870 grinders use the same gears. If you can find one and salvage it you'll be good to go.

    This just happened to my grinder. I don't really want to have to buy a new grinder when a $1 part is busted!!

    Does anyone have a 3D printer? it looks like something that could be printed fairly easily (with a bit of tidy up).

    Thanks

    Breville BCG800 Smart Grinder

    Hi, Dan.

    A friend of mine suggested exactly the same thing. Unfortunately, I don't know anybody with an access to a 3D printer. And Breville is not really a popular brand in this country, so tough luck finding a similar gear from other units.

    I've even asked several workshops that usually make custom gear, but once they see the photo, they told me that it would be expensive since the "teeth" are fairly tight-packed. Plus, they will need to make two gears and join them.

    That surprises me rigs,

    I would have thought it could be easily printed as one gear, and I have seen some pretty high resolution prints that would have trouble printing the gears - they would need a tidy up with some fine sandpaper though.

    I'll keep hunting. If I find a suitable solution how many people would be keen?

    Hi
    I've had my smart grinder for a month now. After dialling it in, we enjoyed several days of great coffee. Despite cleaning it (roughly weekly) I've had to keep making the grind finer and finer.

    So from once getting a great fine grind on '11', I'm now on '3' and it pours through in 5 seconds.

    I can only think of 2 possible causes: a problem with my cleaning (any tips appreciated as I thought access to clear the lower burs was very limited).
    The other... there is a problem with my grinder.

    My wife just ground some coffee on coarse and then on fine settings.... there was barely any difference between samples.

    I'm a little frustrated as I'm using this with a Rocket Giotto and really would like to get quality and consistency back into my coffee making.
    All advice appreciated.

    Thanks

    .......as it turns out, there is a third (and probably more) reason. The different brand of beans. We used Grinders initially then switched to Oro. I just couldn't get the Oro fine enough. I have the 820 model and even after dialing it to 1 and moving it 2 steps finer using the internal adjustment, it still was too coarse.

    So as a final check before taking the grinder back, we bought another prank of Grinders beans. Without changing the settings, it almost choked the Rocket Giotto. I wound it back another couple of steps and it still took waaay too long.

    Maybe someone can enlighten me on how beans can have such a radical effect on a grinder.

    Thanks

    Hi pmarsk
    Head over to the roasting thread - you'll learn all sorts of things about why roast length/depth/profile/beans have a massive impact on grind settings and flavour

    Cheers Matt

    I found a ridiculously expensive listing for the gear on bay, but I managed to track down a Canadian site that sells them for 4.80CAD. shipping is quite expensive but still not as outrageous as the ebay listing: BPBCG820BSS130 | Breville: Main Gear for BCG800/820 Coffee Grinder - Forum Home Appliances eBay link removed per Site Posting Policy

    edit: although it wasn't an ebay link. I've read the posting policy and learned links to businesses are not allowed. However there should be enough info in my post for anyone looking for a replacement gear to find the site themselves.

    There's an iFixit page by a guy who has diagnosed his ratcheting problem as due to a worn "impeller" under the burrs. He's designed a 3D-printed replacement that you can order too: https://www.ifixit.com/Guide/BCG800X...Impeller/62905

    Hello All. Very informative thread and forum.

    I just want to get my fellow Smart Grinder users opinions on my grind consistency (Grinds in my cup is a second issue I am trying to solve too!).

    I am experiencing constant channelling issues on by BDB. I'm wondering whether the below grind inconsistency may be contributing. My settings are Burr on #2, Grind 13 (on the LCD screen). Should I be concerned with this consistency?

    If you have burr settings to change you're in the wrong thread as you have a BCG820, not 800. However, it sounds like you might be grinding too fine. Hard to say because the same settings on your grinder won't produce the same grind on mine. How fine is it grinding? Does it look like flour or more like sand? If it's more like flour try moving the burr setting up to 4 or more and then adjusting the grind setting to dial in. If this is the case it could well be the reason for the fines in the cup. I would occasionally get a few but never that many until I ground too fine.

    Also what does the puck look like after extraction? Do you get a ring of it left after you bang it out or does it come out clean?

    Hi herbie, I've been trying to source a replacement felt washer without success. Breville won't supply them as they claim they are not a spare part. I seems ludicrous that such a fragile oart can't be replaced. Where did you get yours?

    Cheers,
    Rusty

    Heya Snobs,
    Have read through the thread (yikes, there are a *lot* of posts and off-topic arguments in here...), and searched the site, but can't find if there's any difference between the BCG800 and the BCG800XL.
    I've been having a little bit of trouble getting my grind right (fast pour times despite being at finest grind, channelling when using a naked PF), and before I starting shimming things unnecessarily, I'm wanting to make sure that I do indeed have an 800 rather than 800XL, and that there aren't other issues that I should address before pulling the grinder apart.

    There shouldn't be any difference except the voltage. All the Breville part numbers with XL on the end are American.
    How long have you had it? I don't have mine anymore but had to shim it straight out of the box to get fine enough.

    Ah... Thought as much when I could only find a NA manual for the XL.
    It's just shy of 5 years old.

    Hi Rusty,
    When I found the felt washer broken in December 2013, from memory I made a replacement using a spare piece of felt (from Spotlight) I found a center punch to make the washer center hole .
    When I replaced the ground coffee impeller 13 months ago I did not have to worry about not having a felt washer as the replacement impeller hugs the bushing pedestal more closely and does a good enough job of keeping the grounds away from the grinder burr shaft bushing. There is a CS thread on replacing the ground coffee impeller in grinder topics.
    Cheers Herbie.

    Thanks Herbie, glad you solved your problem. My machine was a year out of warranty. The best Breville would do was sell me direct a new BCG820 for $179. I took the offer but I'm not happy I had to spend that amount because of a lousy felt washer.

    Cheers,
    Rusty

    I have just listed a replacement impellor in the For Sale section if anyone is interested.

    Eventually they wear down too far and jam up, rendering your grinder useless.

    So I found my shim kit from 6 years ago as my BCG800 just could not cope with providing a fine enough grind for the BES920 I picked up from TGG's black Friday sale (to be honest it wasn't fine enough for my old 800ES with 53mm portafilter). Easy job to install the kit but even with all 4 shims plus the original shim fitted it won't grind fine enough to clog even the dual wall filter.
    Am I correct in thinking the burrs are blunt?....time to look for a new grinder to match the BES920?

    That doesn't sound right. Apologies for the silly question but are you sure the burrs are both installed right?

    I have pulled it apart several times and re-assembled it, carefully slotting the lower burr into the location tab. First attempt I installed the recommended 1.0mm plus 0.4mm shim and I got a very coarse sand like grind so I added the original 1.0mm shim and it improved slightly, actually got some crema out of the single wall double basket but only after setting to the finest grinder setting. Hoping to choke the basket, I installed a total of 3.8mm of shims and as I wind the knob from Coarse to Fine the burrs squeal at 17-18 (mark "p" of espresso on the LCD). I do notice that moving the adjustment knob results in an almost imperceptible change of the burr position, something I will checkout on a new machine when next at the GoodGuys. Of course the BES920 is my first "grown-ups" machine with proper sized baskets so there is still lotsa learning to do. Beans are from my local coffee shop(Zitto) who is supplied by a local roaster.

    Do you know what date the beans were roasted? Also what happens when you're grinding and you adjust the burrs near the touching when empty point? Have you gone past it while grinding?

    Hi Ninja... I don't have a roasting date, but they go through gallons of beans in their cafe and just scoop 500gm of their freshly opened bulk bag into a heat sealed bag forus home users. They used to get weekly deliveries from Ricca coffee but have recently changed to a different supplier, I'm confident the beans are OK. After some experimentation I went to the finest grind setting hoping to choke the filter and work back from there but it wouldn't even choke the dual wall basket. I'm wondering if the burrs are past there use-by date or the adjusting mechanism is dodgy.

    I doubt the burrs would be blunt. How much are you dosing and do you tamp it firmly?

    Make sure the top burr is definitely pushed down into position before rotating it round to lock it in.

    Hope you get it sorted.

    Also, the dual wall baskets should remain in their box and put right at the back of the cupboard never to see the light of day again!

    Stranger things have happened. I have lost count of the number of people who have posted not being able to grind fine enough and sure the beans were fine, only to try other beans after trying everything else and that fixing the problem (or buying a new grinder and finding that doesn't fix the problem). I think it's worth ruling out given how easy and cheap it is.

    I'd like a dollar for every time this question has been asked on Coffee Snobs.

    Yep the beans are always fresh.

    This is honestly the first time I have "had" to use a dual wall basket in 10+ years but since last Sunday when I picked up the 920 it's the only way I have been able to get a "decent" coffee.
    Today I've fitted the shims and there has been a bit of crema from the single wall dual basket but it was a very watery shot.
    Everything was spotlessly clean on re-assembly and the top burr locked firmly into its slots. I can see tomorrow I need to get some beans from my favorite roaster, some digital scales and eventually a proper tamper. At the moment I tamp firmly with the supplied tamper and use the Razer thingy so at least the dose is constant, interestingly I still see what looks like an imprint of the screen in the puck, time to look for a 5 cent piece.
    This has my interest... EUREKA - MIGNON SILENZIO - electronic grinders

    As far as dosing by volume goes, the razor matches pretty well with the 5c test.
    You should see an imprint of the shower screen on the spent puck. That is normal.

    If you look to buying a tamper, you can't go past a Pullman one. Bit pricey but unrivalled in my view.

    If you dose by volume, once you get to know how much to grind, once you have tamped, don't use the razor anymore. It roughs up the surface of the puck and retamping doesn't make it right again. It's a handy tool for learning but after that, put it away.

    Alternatively, dose by weight. I'm too lazy for the extra process so I still just use volume. BCG820 has a timer for dose control.

    So I have some fresh beans, roasted exactly 7 days ago. Thoroughly removed and cleaned everything with vacuum and brush then reassembled and carefully ran the machine without the hopper.
    The burrs just started to clash at the "ss" of espresso mark....bewdy. In went the medium roast beans, grind looked OK but shot was watery and only went to "4bar" on the gauge, puck was sloppy.
    Gradually increased the to the finest possible but still no improvement other than gauge rising to "5.5bar" so I guess the grind adjustment is working.
    Cleaned the grinder of the medium beans and put some dark roast, oily Costa Rica/Indian Tiger and at the finest grind it managed to choke the pour "9bar" with just a few drips in the cup after 30sec.
    Backed it off 2 tabs and a watery mess, increased by 1 tab and a slight improvement...very inconsistent.
    It appears to me there is possible wear in either the burrs, upper burr carrier or adjustment mechanism. Apparently there is a couple of screws on an internal grind adjusting gear that can be removed to enable even finer grind (I have already installed shims) so my next step is to completely dismantle it to get at the internals.
    Interestingly after removing the medium beans and cleaning I could not get the burrs to clash again.

    Are you using the tamper that came with the machine? How tight or loose is the fit in the basket? Water will find the path of least resistance, so if the tamper is not matched reasonably well to the basket, it won't be tamped as firmly around the edges and you will get what is known as channeling.
    You could experiment with the single shot basket, as the tapered sides will help to reduce this effect, and see if you get a better result.

    With the amount of shims you have used you should be able to choke the machine so something is not right somewhere.

    I think you are on the money....at this stage I have not strayed from the provided tamper and it is a loose fit in the basket. I noticed what looked like about 20mm of channeling around the edge of the basket so I tried the single basket and it choked.
    I always planned on getting another tamper but decided to wait to see if the supplied baskets were up to scratch.
    I purchased a pair of single wall baskets for the Breville ES800 I have but got a better result from converting the dual wall basket to single wall.

    I had my Pullman tamper matched to the basket on my 900. When I got my 920, I found the double basket was too big and I was having similar issues although not to the same extent. I kept using the basket from the 900 at first but ended up buying a Pullman double basket. I actually bought a new base for my tamper as well, matched to the new Pullman basket, but as luck would have it, it was the same size as the one I had so I was able to return it.

    I would highly recommend the same combo (Pullman tamper matched to Pullman or vst basket), although they are on the pricy side. They are made better than most others though.

    Sorry for off topic rant.
