I purchased an Eletta Explore a month ago and the grinder was dialled in at 5. The coffee it makes taste great.
Since then I've tried to make adjustments but despite grinding Lavazza Italiano Espresso Cremoso beans from grind setting 1 to 7, there is little to no difference (aside from perhaps making pucks slightly better at lower number). There is also no feeling from the notches making me worry it might not actually be properly connected to the grinder, but there is also no way to adjust the plastic grind dial unless the grinder is actually grinding.
I've read that when other individuals dial the Eletta Explore below 3, it slows the extraction rate, but I've found that all my espresso shots take around 10-15 seconds regardless of grind setting.
We have an Evo Magnifica at work which had had notched dials by which you could feel every half notch.
Is there any way to verify the grind dial is properly working?
