De’Longhi Eletta Explore: “Couldn’t deliver the drink. Adjust the coffee mill…” or “…Reduce the aroma and try again”

What De’Longhi says to do
- Press OK and turn the grinding dial up by one position (section 6.4), or choose a milder ‘Aroma’.
- If a filter is fitted, deliver a little hot water until the flow is regular; if the problem continues, remove the filter (section 18.2).
