You may be surprised what you can achieve. I've owned a couple of Krups machines and on occasion managed to produce some pretty drinkable coffee, though it was a bit of a struggle.
Krups make several models, can you tell us which one?
A problem I had with mine was in the design of the portafilter basket. It was fabricated in two pieces, and when I got the grind and tamp about right it would blow the basket apart. I destroyed four in total, and the last time I threw it away and bought a La Pavoni lever machine, which makes a cappuccino fit for a king.
