Great video and thank you, I had exactly the same problem with the grinder and solved it by following your instructions. 👍👍

Great video! I've just bought a brand new machine, but always like to know how to fix it when it eventually packs up.

So, the 3 ball bearings + the springs form a slip clutch that prevents the grinder from grenading if a foreign object happens to fall into the hopper. I tore my grinder down completely as per the video, only to find that the 3 ball bearings were exactly where they ought to be, and the spring tension was excellent. However, I noticed a circular score mark on the back of the inner grinder (the part the moves), exactly as if it was slipping over the ball bearings. I carefully examined the waste coffee that I'd dumped out of the grinder while disassembling it... and much to my surprise, I found a small black plastic disc, maybe 1/3" diameter & 1/8" inch thick. I suspect it was from the 5lbs commercial bag of coffee I was using, because it was not familiar to me from anything in my apartment. It was the little plastic disc that was preventing the grinder from operating. Delonghi actually has a troubleshooting tip for this exact "No grind, sounds funny" problem, which is to put a vacuum hose over the top of the grinder to clean it out. However many models have that annoying metal grill over the grinder that completely prevents you from doing this. I reassembled mine and deleted the metal grill, so if this happens in the future, I can just pull out the shop vac & suck out the grinder. Does this make the device more dangerous? No, not at all, you still have that black plastic cap over the actual finger remover bit, and really, if you are stupid enough to try jamming your finger in that little hole, then you certainly deserve whatever bad thing happens next. However, if you have children, and they mess with your adult toys, you might not want to proceed with this delete mod. Thanks for the great video Ravraid.

Thank you very much. This video helped me a lot.

Thanks for video.good job.

Great video! Mine sounded identical. Found a piece of plastic in the grinder. Spun motor and grinder by hand and were smooth so I didn’t take the grinder any further apart. Put all back together and now it ground a little coffee but stopped and got the fill beans message. Not clunking anymore but still not 100%. How’d you correctly align the fine/coarse knob when re-installing?

Thanks for the video! And jokes. I was wondering what's that kill switch you use for tests? Sounds like a good buddy to have for repairs. Thanks

Great video, thank you! I followed your instructions and nicely cleand the grinder, but still asks for filling the bean container. The grinder makes a healthy noise, and as far as I can tell it grinds. However, I see no grinded (or any) coffee pushed into that vertical tunnel from the grinder. Do you have any idea that what might be the problem? Thank you in advance!

Hi Thanks - great video. I am getting the 'fill beans container' message too. Not making that noise but wondering if the cause is the grinder needing a clean? What do you think?

Thanks for the video...Did this fix the problem?

Great video. I was wondering if you could help. When my coffee grinder is grinding I can see it getting stuck in hopper where you would put preground coffee and not making its way down into the brew group. This happens at least once a week. I clean brew unit at least once a week. Lube it once every 2weeks. I also deep clean the machine once every 3months. Any ideas why it is getting stuck in hopper and fresh grinds not making down in to brew group. Again it doesn't happen all the time

My adjustment gear/ cog came off before I got a chance to mark the alignment. Any hints on how to get it tuned/ aligned again? I noticed there is a small v notch in the big gear, and 3 lines printed on top of the small cog. Assume they are meant to line up with something. Can't quite see in your video where these notches / lines line up.

Hey. This helped so much. Did the exact same When placed back on it sais “general alarm” please wait “ Any thoughts ! ? Infuser is also stuck

Hi, Would you recommend grinding rice once per month to clean the residues?

Mine does not spin at all. I bet it's the ballbearings that popped out because the grinder height gear on the motor is misaligned. that said, what kind of power are you applying? dc, ac, voltage,? thanks.

How do you get the ring back onto the grinder, to hold the gears in place? It came off but wont pop back on. Its like it shrunk! Should i heat it?

I was exactly what u done on the video and I managed to get one of the springs jammed and now I can’t find anywhere to buy it , any ideas? Thanks!

Hello! I have delonghi Perfect cappuccino and grinders does not stop, grind all the coffee. what can it be, sensor ...? thanks!!

I had mine for about 5 years and did 30,000 coffees and then one day the controller started smoking - purchased another one and in 11 months the grinder has malfunctioned

Hi all, I'm hoping someone can help figure this out. I'm lost with what the problem is. Issue: water does not flow out when using the bean grinder It merely drips out, but only a small small amount. What does happen: the water flows and machine makes coffee when using pre-ground water flows when hitting the rinse button the grinder works and creates pucks the Pucks dispense
