when the red light comes on showing the used coffee holder is full, after emptying it and cleaning the machine, the light stays on, and it will not switch back on again. Can you please help?
This light also comes on if the grinder is jammed either with whole beans (unlikely) a small stone (possible as they can sometimes get into the beans) or ground coffee (most likely, especially if high roast, oily beans have been used, which are very sticky)
