Does not fit into any DeLonghi EAM / ESAM Kaffeevollautomaten

I had the problem that has not thrown my first brewing unit after three years the pressed coffee grounds properly into the container. Many ended up in the middle of the machine and thus had to be frequently cleaned. This error was led back to the brewing unit by several recessions. Since I have not found at Amazon infuser directly for my Prima Dona ESAM6700, I walked out of the designation ESAM. The brewing unit looks just like my first and is also an original but unfortunately there are small differences, like me the dealer wrote. After half a year I had with the new the same problems and that is why I contacted the dealer. I could see the brewing unit back by a very generous customer dealer again. The description from Amazon would be better adapted to the individual types and therefore could have been no problems.
