I don't understand it. Before Senseo was released in the U.S., I bought a Senseo machine from Germany on eBay and used it in the U.S. with an electricity transformer/converter. I loved the coffee it produced! When Senseo was released here, I quickly bought two units, so my wife and I could have a machine at work. Strangely, neither American-made machine produced coffee that tasted like the German model. There are two main differences: (1) the coffee from the American machine tasted bitter and stale; (2) the "crema" from the American machine was foamy, rather than creamy like the German machine. I used the exact same Douwe Egberts pods, from Belgium, so the difference is not the coffee. I even tried using the same water supply, and that didn't matter either. Something is different about the machines, but I don't know what. I'm hoping someone else has experienced this and knows whether the issue has been fixed or if there's something I can do to fix it, as my German machine is starting to leak and may need to be replaced soon. Any suggestions?
