Lets us know how it goes with the new one. BTW, what grinder did you have previously before you purchase the Atom 75?

Well we got given a new grinder. Im going to take the top off in a week and see how it looks.
Certainly when I looked on the old grinder it looked NOTHING like the above pictures.
Sorry but that single dosing stuff is just a waste of time for us, we want an on demand grinder that works - I'm not willing to spend more money on something that this grinder should do easily.
So far so good on the new one.

Can confirm, I have this year's Atom 75 and the screws are sitting flush.

I see Lancruiser, makes sense. The 75 must be different to the original.
Here is a thread on the Mignon explaining the problem and Eureka's response saying they were aware and it was rectified - https://www.home-barista.com/grinder...t73522-10.htmlLast edited by 338; 11 July 2022, 07:32 PM.

338 , I see.
The "rubber sleeve" does not go down this far. There is a "landing" before that in the carrier that it sits on. See the markings on the picture below.
This is the a picture with the gasket. Hopefully, it's not too dark.

lancruiser you can see the bolts highlighted here and how they stop the the rubber sleeve seating correctly

Hi Lancruiser, I haven't owned a 75 like yours but I owned an Atom 60. My description was probably poor. There is a round rubber tube which goes in to the throat. It would hit the base of the throat and seal on the sides. As you can see on the base of the throat the bolt threads protrude pretty heavily, my guess why this 75 has the problems. I believe it affected a number of Atom models, no idea if the 75 was among them but the reason was a batch of too long bolts

I may have misunderstood your description. I own a similar grinder, the "rubber sleeve" actually goes inside the top carrier. The seal is actually quite good.

What we are seeing in those photos may (or may not) relate to an issue with the bolts for the upper burrs. Eureka installed too long bolts on the upper burrs. The top plate was drilled through, presumably to save problems when bolts on or just over the required length were installed. With the much longer bolts they stopped seals working properly and were especially bad with bellows. The solution was to install bolts which did not extend through the top carrier. Eureka was aware of the problem and offered replacement bolts (or as they are metric get from any hardware store in Australia).
If we look at the throat of the grinder in question you can see the bolts extending well past the top carrier, probably by 4 or 5mm. This is probably the worst example I have seen on the net, most were 1 or 2mm. This would definitely stop the rubber sleeve in to the throat sealing well.
Not sure if this is what we are seeing here but it is a reasonable guess.

The Eureka blow up system was available before the release of the Atom 75. Eureka also states that the 75 is compatible with the blow up system. The rubber gasket from the opening on top extends to the grind chamber and there is also rubber gasket connecting the chute to the grind chamber. It does looked like Eureka designed the 75 for the blow up system. I think there is a lot more to the story that comes with those pictures. Perhaps the one or more of the gaskets were not in place?

I use Atom 75 for a single dosing for months and don't have such a messy problem: the chamber clean as it was brand new, however I don't use bellows but a gentle tap while running clears any remaining grinds. Just make sure that all seals sit tide and add shim if required.
When I use it with a hopper, 0.25sec clears old grinds, no clogs whatsoever.
I've noticed that very dark, oily, roasts tend to clog any grinder more than light & medium roasts.

The Atom is designed to be an on demand grinder with a hopper full of beans. That makes sense now why the bellows causes this issue inside the Atom. The Mignon series has a different chute and can handle the high pressure air from the bellows. The new San Remo All grounds May suite a bellows better.

The clump crusher was made of tin. It was so flimsy that it bent upwards.
So you had no clump crusher.
Ground coffee was literally coming out the chute in cubes.
I really cannot remember the latest model.
Doesn't matter.
I won't purchase a Eureka for at least another 5 years.
By then, who knows if I'll need another grinder and if I'll opt for another brand.
What bothered be about eureka is that they admitted the model were faulty but never really followed up with me.
In fact they said the fix would be soon, a week or two. But that turned into about two months.
That's when I returned my Helios for a refund and wrote off eureka.
Mistakes happen.
It's how you handle it that matters the most.
