A:Answer I'm having this same problem, and I think it's because I removed the rubber piece around the needle. It worked fine before that. Do you still have the rubber piece in the machine? I have been back and forth with cuisinart about this... This is using the refillable cup that comes with it. I had a problem with the commercial Kcups as well, but they told me to push it down until I hear the pop, and that has fixed that issue.
