Query: Picky machine but it makes good coffee

This is the first espresso machine I have owned so I have no other product to compare it to. So far I have been happy with my Krups, although I have already had to replace the gasket once. The machine seems to be VERY picky about when it will and will not pull shots. If the espresso is not loaded just right it refuses to pull the shot, which causes water pressure to build up (this is how the gasket broke). Bottom line: the coffee tastes great, however, sometimes making the coffee can be a bit of a hassle.
