Where to start … i,ve just 'cleaned' my Specialita down to the burrs and reassembled everything without any issues. Now, just cant get a decent grind despite it working aok beforehand. I've found the 'chirp' point and backed off an 'incy wincy' bit which is as close as i can get and still it's nowhere near fine enough. Beans are on their way out datewise, being roasted 4 weeks ago now, but can this cause the issue. I'm at the point now where i'm sure the burrs are close enough to touching and when i power the grinder off you definitely get a 'tinging' noise, not during the grind itself but just as the machine winds down, so i'm reluctant to move them any closer. Have i missed something here? Just pulled latest shot which started at 3 secs despite there being a further 7 secs pre-infusion, which is my normal setting. The grind just isn't fine enough. Worth messing with or should i just get a niche 🙂

When you removed stuff did you mark location, I forget if the burrs can locate in multiple positions with the grinder

What Jake said. If you removed the burrs, you need to make sure they are sitting properly and aligned/level. If you didn’t remove the burrs from the carriers, then I am not sure.

I removed and cleaned both burrs, three screws to each. Can't see that reassembly would be affected? It has crossed my mind to maybe replace the burrs with new although they look in an unused condition to me,

@"skylark"#p51503 - the only thing I can think of is that the burrs are misaligned, or you swapped them around, but I can’t see how that should make any difference. If I were you, I’d repeat the process: take it all out again, clean all the surfaces very well, and re-install the again. Remember, when tightening the screws, don’t do each individually fully and then move to the next one. Instead, go over all of them gradually. Good luck.

Thanks. The burrs were really clean and the screws not that difficult to remove. I've not seen any information which advises that burrs need to be re-seated as before after cleaning so i'm guessing its not that. I will remove the cover and recheck all the screws but its because i'm virtually at the touching point and still the grind isn't fine enough thats the strange thing hmmm?

@"skylark"#p51507 - something is not right. So best to revisit what’s been done. 👍 - there’s no reason the burrs got blunt all of a sudden. Something must have happened in the process, and the best way to check is to review the steps. Or… Have you removed the chute screen, or maybe didn’t put it back properly?

As MRS has said, take everything back out and refit. If it’s still not grinding correctly do the felt marker alignment procedure to check that the burrs are aligned 👍

I've had it apart tonite and all 'looks' to be ok so its mystifying. I have a low attention span and if a product doesnt work as it should its normally 'back benched' until i 'can' be bothered to fix it. So, as i need a working grinder i'm starting to look elsewhere. What do peoples think of the DF83 in lieu of a Niche Zero (it should be better, yes, bigger burrs). The DF83 is down in price it seems and a good deal cheaper than even a Duo. I'm thinking a white DF83 will do me for now, anyone able to talk me out of it, quickly?

The eureka are a poor grinder imo Df83 will do for the price but for £60 more you get better burrs and Better workflow in the duo but there not in stock I think the white ships end of sept.

> @"skylark"#p51507 I will remove the cover and recheck all the screws but its because i’m virtually at the touching point and still the grind isn’t fine enough thats the strange thing hmmm? Sounds like it's misaligned for some reason?

Problems with my Specialita ...

Grinders around 9 months old, looked as clean as a whistle when i dismantled it.

The burrs are also in ship shape condition but for some reason i’m thinking i’ve ‘moved’ their physical orientation in the carrier and that in itself is the cause of the misalignment, the burrs having ‘settled’ in over the previous 9 months. My mindset was to put a new set of burrs in from scratch and then let them similarly bed in, does that make sense or am i just wasting dosh that could go towards another grinder.

Cuprajake

you wont need burrs in this case,

did you have both burrs off at the same time? im not sure if there are top and bottom burrs with the eureka

Cuprajake

Yeah, both burrs off and cleaned. No problems there at all.

Cuprajake

um, id use a bit of tape to mark the upper burr carrier and then mark a black dot on the grinder, rotate the top burr in all three places and see if you have any luck,.

skylark

I fixed it!

Reseated top burr by one turn (must’ve touched lucky) and its back to good with no ‘tinkling’ nosies. Tried a 20g dose this morning which ground so fine that it was a struggle to get it into a 20g vst basket with comfortable headroom. Do vst do a 30g basket I wonder as I often pull twin 15g shots singly? Maybe a larger basket split between the two of us would be the way to go. Or, would 30g fit into a 25g basket which is the largest i can see???
