I bought the De Longhi Lattissima Touch about 2 years ago. The problem is that the arm (or nozzle) of the milk container has cracked (I don't know why, because I always clean it by hand, so I don't put it in the dishwasher). Now, of course, the milk always spills out. I can't find a spare part anywhere. Is there not one? Thank you for your answer. Cécile
