The screen say "Empty Grinder" - how do I fix it?
The machine seems ready to go- it says "Select shot size" as it normally does- but when I select a size, it starts like it should but makes an odd noise like it can't grind anything. Then it displays the message "Grinder Empty." I've checked both the water and beans and they are full. I've also turned the machine on and off. Help please!
Is dit een goede vraag?
