Ek-43 grinding differently after each cleaning.

[wheat egret]

Hey! I have an issue with my Ek-43. It seems to me that after every cleaning the grinder is aligned in a different way. Even the chirping sound is different each time. Any ideas what might be the issue?

From my observations it's not only after the cleaning, but also when it's in use for a few days. It's a cafe setting and the grinder probably grinds up to 1kg of beans during busy days. I do a cleaning once a week. Maybe that's not enough?

What roast profile is the coffee that you are using?

Check the tension on the set screw for the dial. That’s what actually determines your zero setting and is totally separate from opening the grinder up. This can come loose and drift. Careful tightening it. You can crack the plastic and then it won’t be able to tighten. You’d have to buy a new piece.

Do you open it up when cleaning? Know that there’s two ways the carrier can go on the shaft. If you don’t put it back the same way your alignment changes

I'm single dosing many different coffees from a relatively light filter roasts to a nicely developed espresso profiles, but far from burnt.

I use an allen key regularly to set the burr touch at 0.3 and it's pretty tight after I set it imo. Thanks for the warning, unfortunately I already broke one in the past and learned to not make it too tight on the new one that I had to buy.

Wow, do you mean the two ways as 180° rotation? I never thought about that!

Yeah, mark it with a sharpie while they’re together

Thanks! I'd never think it's not symmetrical.
