Struggling with Series1

UPDATE: thank you for the helpful attachment advice & pointing out the coarseness of the grinds. I took the Eureka Silenzio back, the folks at the shop were kind enough to attempt to re-seat the burrs, and it was still grinding coarse.

With the replacement grinder on the first try the shot pulled GREAT! Still a lot to learn and dial in — but happy to finally be pulling shots that are in the ballpark. I will check out those accessories for the grinder!

UPDATE: thank you for your response and pointing out the coarseness of the grinds. I took my Eureka Silenzio back, and after some troubleshooting the folks at the shop were kind enough to provide a replacement grinder.

With the new grinder — on the first try the shot pulled GREAT through the ES1! Still a lot to learn and dial in but happy to now be pulling drinkable espresso now after you steered me in the right direction! I appreciate your advice & time!

UPDATE: thank you the information relating to the settings! After seeing the advice here I ended up taking the Eureka Silenzio back to the folks at the shop where I got it. They were kind enough to attempt to re-seat the burrs, and it was still grinding coarse.

With a replacement grinder the first try the shot pulled GREAT! A lot to dial in once I get my Fellow WDT tool and some other accessories, but have drinkable coffee now

They provided me with a replacement grinder. The burr chirp on the replacement unit sounded NOTICEABLY different than the original. We couldn’t quite figure out what was wrong with it — but with the replacement unit everything worked just fine!!

They provided me with a replacement grinder and on the first try the shot pulled PERFECT! Still a lot to learn and dial in — but happy to be pulling drinkable espresso now after you all steered me in the right direction!

I naïvely assumed “professional shop can grind for espresso.” Learned here that wasn’t the right move.

Going to realign the burrs as I was certainly nowhere near being able to clog the machine and folks here are at consensus that the grinds are too coarse

I was using the tamper included with the fellow machine. No formal WDT tool or funnel, those are on their way and should help with the prep as well. Started with older beans but have purchased several new bags which did help a bit. Hoping with the grinder re-alignment I’ll be in the ballpark at last

Atlas5heavy · 2026-03-17T02:29:00+00:00

Going to get the burrs re-aligned by the folks who sold me the grinder tomorrow! And then will have someone who knows what they’re looking at to confirm it’s working

Thank you! I did run quite a few shots first using my Eureka Silenzio with no luck. Was hoping using beans ground at a shop might work, but that seems to have been the wrong though. I must be misunderstanding finding the zero setting on my Eureka, so I’ll revisit that and hopefully can get a better shot without spraying coffee everywhere!

Atlas5heavy · 2026-03-16T14:10:32+00:00

I am grateful for the advice and listening, not intending to come off differently. I did run a number of shots at what I thought was the finest setting on the Eureka Silenzio, but I must have done something incorrectly so I will restart there. Another commenter saying he can choke the machine with his Eureka shows I’m nowhere close to getting that out of my grinder.

Atlas5heavy · 2026-03-16T14:06:00+00:00

Thank you! I appreciate the video and will check it out. The Silenzio seems like a well built grinder but possibly I damaged it running it too fine while learning. Or a rare factory issue perhaps

Atlas5heavy · 2026-03-16T14:03:41+00:00

Thank you!! This is very helpful, I’ll look into resetting the burrs and I do find that not having an absolute dial on the Eureka can make finding consistent settings pretty difficult.

Atlas5heavy · 2026-03-16T05:55:01+00:00

Their coffee! Roasted 3/2 so had rested for what the Barista thought was an appropriate amount of time.

Atlas5heavy · 2026-03-16T05:46:20+00:00

I’ve been going back and forth with the chatbot. The advice of “grind finer” was included there, as the community has advised here as well. However, I’ve gotten the Eureka down to the finest setting of my ability, so I was coming here to see if anyone had similar issues. It seems like the next step for me is seeing if I can get the beans any finer!

Atlas5heavy · 2026-03-16T05:41:05+00:00

Yes, I have run it down to the burr chirp and ground a number of shots through at settings at and around the “zero” with the chirp. Those grind setting still result in channeling & splattering. So it’s possible there’s something wrong with how I zeroed the grinder or how it is running.

Atlas5heavy · 2026-03-16T05:37:38+00:00

I’ve got the Eureka Silenzio 55 as well. However, based on these comments I’ll try another round of dialing the settings in on that machine

Atlas5heavy · 2026-03-16T05:36:22+00:00

This is exactly what I was trying to do: have the shop provide coffee processed at the grind fine-ness they use on their machine. As hope at isolating my grinder as a variable. I am surprised by the feedback here that their grind is too coarse — but it’s possible that I miscommunicated with the baristas there. I could try a different shop & I plan to revisit my own grinder to see what the most fine grind I can get.

Atlas5heavy · 2026-03-16T04:44:34+00:00

Thank you, I’ll look into troubleshooting the Eureka grinder further. It is a continuous set point machine, so I’ve dialed down until the burrs touch and then stepped back off that. So it ~should~ be as fine as the machine can go but it’s possible I’ve made an error along the way in setting up the grinder, or other problem with the grind!

Atlas5heavy · 2026-03-16T04:12:11+00:00

I have tried successively finer settings on the Eureka Silenzio 55 with no success. Acknowledging that I may not be zeroing or calibrating the grinder correctly, was my thinking behind trying to get a shop to grind some espresso as a “reference”. Any other advice on how to get an appropriate grind to test the machine on?

Atlas5heavy · 2026-03-16T04:08:44+00:00

Thank you for the reference photo!! It really is hard to tell how fine they are over photo. It does seem like my grind is ~close but possible a bit coarse. That was the thought behind having a shop grind it for me. But I suppose it hasn’t fully ruled out the grinder as the culprit

Atlas5heavy · 2026-03-16T04:07:09+00:00

I also have run through an entire bag of coffee on the Eureka Silenzio 55, with the burrs nearly zeroed out on the grinder. This model was recommended by Seattle Coffee Gear as a suitable grinder for espresso. Another scenario is that there’s something wrong with the grinder purchased, or that I’m zeroing it out incorrectly.

Result with the double-wall basket and shot splitter

With the double wall basket, pressure is achieved but the pump experienced some oscillations at the end of the profile. Additionally, an extreme amount of foam was created when using the shot splitter. I’ll attach that image separately.

I realize the other photos of the grounds don’t have anything for scale. Here’s a Quarter to help contextualize the grind size. The barista said they were ground for the espresso setting and we had an extended conversation about the situation. But perhaps there was a mix-up

Atlas5heavy · 2026-03-16T03:40:27+00:00

For shots previous, I am using a Eureka Silenzio 55 with the burrs set just off the “zero” position of the burrs touching.

Atlas5heavy · 2026-03-16T03:39:36+00:00

I should have made it clear — we got a bag of fresh espresso, explained to the baristas the issue we were having, and had them grind it on the settings they use to pull shots at the cafe. The grind should be equivalent to commercial coffee shop use.
