That is too early to tell. While I do like the concept of the E65SGbW, I'll reserve judgement till it's been out in the wild for a couple of years before making that determination.

However I really really hate adjusting the grind size on this. Even if adjusting is stepless which is ideal, the locking on it makes the grinder essentially has stepped adjustments. Sometimes when you have that grind size setting that you want, locking the adjustment ring just shifts the adjustment even up to two points (and the corresponding DDD measurement confirms the change too).
We found the same at the beginning. However locking mechanism is there only to stop people messing with it or accidentally being knocked. Solution is that you don't need to lock it, which is how we run with it now, left unlocked. No issues whatsoever...

I did try leaving it unlocked at the beginning but the grind size did move while grinding, at least as to what is reported by DDD. I'll give it a serious try next time.

I'd assume it doesn't move after a while of use due to wear or the grease has given away, hence increasing the friction and resistance from moving while grinding.

Hi Bobby - I also have an E65S GbW and would like to access the service menu. Would like to check scale calibration and also reset the DDD 0 point as it is wrong now that I have adjusted the actual grinder zero point. Would you be able to share the password with me? Assuming its the same? I have run into the same issues getting it through official channels and am a bit annoyed by it tbh. That aside the grinder is amazing. I don't tend to lock the grind adjustment so haven't run into many issues with it wandering/jumping between steps.

cheers

I have also never used the locking mechanism on an E65S. In fact my initial guess at its function (before the retail launch and before a manual was published) was to switch the operation from stepless to stepped, since the lock doesn't actually lock anything in place and the adjustment wheel could still be turned without excessive force. I've never seen the wheel slip when unlocked across multiple E65S grinders and I don't think that is intended. I would contact Mahlkonig about it if it persists.
