Hi guys!
I am having this situation with my em0480:
1.- After a complete clean and correct re-assembly I set it to a grind setting of 13.
2.- Pull a shot where my EM6910 pressure gauge reads just in the top limit of the "suggested area" (good for me)
3.- Grind for a second shot.
4.- Pull the shot again and the pressure gauge reads way over the "suggested area" (maybe near the red zone).
So I decided to take a good look at the grinder I see this coffee built-up in the top burr:

As you can see, there is a LOT of coffee there... So when I clean it, the setting of 13 grinds as it should (pressure gauge again where it should). This evidently affects the grinding of coffee...
Does anyone know if there is a fix to this? Or I have to clean this every time I grind coffee?
Thanks guys!
ps: Tamp pressure should be the same in all cases
