    K3 Cleaning Grinding Chamber

    Gene Cafe Coffee Roaster $850 - Free Beans Free Freight

    How often do you remove the top burr to clean the burrs and grinding chamber.

    I run Grindz through the machine about every six weeks and I grind 1kg every ten days.

    Its a bit of a pain dismantling the grinder so I suspect not many do it ::)

    I clean my grinder burrs about once a month. Give it a good vacuum then clean parts with various tools/cloths.

    Is there a place to buy Grindz in Australia? A web site?

    This is exactly the thread I wanted to read.

    Any tricks for dismantling? Ive read the manual but how do you remove the metal position indicator easily without scratching it?

    Secondly does Grindz really work? Do you taste Grindz in your next cup?

    Re: K3 Cleaning Grinding Chamber

    The manual says:

    "Remove the position indicator cover located on the grind regulator with help of a flat-head screwdriver"

    A thin knife blade will do just as well.

    After using Grindz run a double shot of beans through the grinder to clear out any residue.

    I have taken mine half way apart to brush the insides clean. Its simple but not a quick job. I might try the Grindz next time......

    Does the "Grindz" alone do a good job or do you still need to take the grinder appart for a really good clean?

    If youre expecting it to work miracles I think you would be disappointed.

    If you use grindz routinely, it will pick up and clean out excess coffee and oils. Having said that, if youve never used it before I think its a good idea to take apart the burs and give them a good scrub from time to time and before first use of grindz - some of those pesky little coffee particles can be quite stubborn and really wedge themselves in place!

    Thanks Dennis.

    Ill try Grindz monthly and manual clean once per year...... This should do the job.

    Nothing can go wrong if you follow the instructions AND dont try to force it when reassembling.

    I marked my usual setting with Liquid Paper and I write the setting down just to be safe ::)

    Re: K3 Cleaning Grinding Chamber

    Not that I have a K3, but I pull down my grinder about monthly, maybe six weekly when Im slack, for a proper clean.

    I have just purchased my first few bags of grindz from cuppacoffee and my plan is to use them in between proper cleans.

    I guess it depends on how fussy you are, but yearly would really not cut it for my fusspot demands. Remember grinder is everything when it comes to coffee, and old coffee oils are rancid! Having used the grindz once so far I was very impressed - worked really well, but that will never reduce my desire to pull it apart and manually clean it out.

    Me either :o....

    I think the smell alone would put me off drinking coffee forever.... Well, maybe not ;)

    Ive got into the habit over the years of vacuuming out the grind chamber, burr assemblies, etc at the same session that I do my weekly thorough clean of the espresso machine. Since Im in the mood as it were, it only takes an extra five minutes of my time and prevents significant accumulation of coffee oils and grounds in difficult to access areas. A cotton bud or three takes care of anything that the vacuum cant shift....

    Too easy really. About every three - four months Ill go the extra yards and thoroughly clean out everything I can get to. Even this only takes about 15 minutes to do, so no excuse not to really.... ;)

    I agree. Im a bit daunted by the idea as well. The other night I thought Id have a go but I still couldnt see how to remove the metal position indicator without wrecking it. The manual says to use a flat head screw driver but it doesnt seem obvious where to put it and where to lever it off. Any advice??? :-[

    Re: K3 Cleaning Grinding Chamber


    Theres a small cut out on the right hand side under the metal indicator - at least there is on mine rightly or wrongly ::)

    A very small flat blade screwdriver can get a purchase in there and with a twist off pops the metal bit.

    Re: K3 Cleaning Grinding Chamber

    Thanks for that Rusty. I must be blind as I couldnt see that cut out. Ill have a look tonight with my glasses on this time *:-/

    I know this has been discussed above but if I make 5 cups a day on average what is a good *maintenance routine on the K3

    eg vacuum or clean shute fortnightly
    * * grindz monthly
    * * dismantle & clean burs quarterly

    Does this look OK? Any suggestions?

    Re: K3 Cleaning Grinding Chamber

    I grind four doubles daily - thats around 3kg/month.

    I vacuum the chamber at the end of each day. I bought an Electrolux "Flow" compact cleaner and the tube fits nicely into the chamber. I need to dislodge the odd bean that refuses to budge 8-)

    Grindz every six weeks

    Dismantle and clean burrs quarterly.

    Works for me.

    Re: K3 Cleaning Grinding Chamber

    Sounds good rusty, however, Im not sure about vacuuming every day, too busy for that but what I generally do every week or fortnight is clean out the chute with a pipe cleaner. The advantage is they are easy to bend and they do a good job.

    Re: K3 Cleaning Grinding Chamber

    Off topic a little but the manual says you should change (K3) the grind setting when the machine is on and running.

    Is that true? Does it matter or could I damage the machine by altering the grind when its not on? All my other grinders (Iberital challenge and Sunbeam) were adjusted when the machine is not running which seems more natural.

    Re: K3 Cleaning Grinding Chamber


    I believe adjusting the grind while the machine is not running carries a risk of gunking up the burrs, making them harder to clean ::)

    Re: K3 Cleaning Grinding Chamber

    As far as I know the only danger is tightening the burrs and jamming some grinds in between them. Loosening would be no problem.

    Since I grind every shot separately and empty the grinder every time there should be no issue either way.

    No, this is not the problem....

    The issue is, with the grinder having been used at a nominal setting for some amount of time, a certain amount of coffee particles build up around the burrs and are only loosely adhered. If you then adjust the burrs closer together, some of these particles will become trapped between the burr-plates. This can effectively lock the burr-plates together so that when you start the grinder up, the motor has to overcome this extra load in order to spin up and do its job. Sometimes the extra load will be more than the motor can deliver, leading to a stalled motor condition and possible motor burn-out.... Dont think this would be covered by warranty either.... ;)

    Safest option before adjusting the burrs finer, is to start the grinder then slowly and carefully reduce the setting until youre happy with the output. Although it wont do the burr-plates any real harm should they lightly touch, if you apply enough force then damage will follow. Easy and carefully does it ,is the rule to follow.... 8-)

    Thanks for that Mal.

    Heres what the user manual says on the subject:

    "Note that you should only change grind settings when the machine is on and burrs are in motion. If you do not do this, the burrs will gunk up and cleaning will be required.

    Changing the grind settings when the burrs are not in motion will
    cause the grinder to only make very coarse grinds or no grinds"

    When in doubt do what the manufacturer says * ;D

    Well.... :-?

    Thats a goodn Rusty. Never heard it put like that by a manufacturer before so I expect an awful lot has been lost in translation somewhere along the line.

    The explanation I wrote above is actually what happens so I dont know how that ends up as gunk and only providing coarse or no grinds. Maybe they were intending to refer to the motor winding varnish which, when overheated, can melt and dribble out of the bottom of the grinder and gunk-up the benchtop. Dont know about causing coarse grinds but will certainly lead to no grinds.... ;)
