Just wondering if anyone has one of these Tassimo machines. I bought one thinking it would be good for travel and indeed it does make very good coffee and hot chocolate. However, when I just use it for hot water by re using an empty milk disc or the cleaning disc there is a slight smell of plastic to the water and resultant tea and also a slight after taste. Just wondering if that's something that will improve the more I use it or if there is a fix.
