Man and I've been there with my that model acting up, and it turned out the filter basket was all gummed up with old grounds... Give that a good clean, maybe soak it in some hot soapy water for a bit. Works great.
If that's not it,, check if the water reservoir has any blockages or if you're using the right amount of that model. Too much can clog things too. Anyway, simple stuff like that saved mine from the trash heap.
