If you look up at the top needle you should see a black rubber grommit around the base (top) of the needle. This presses down on the top of the coffee pod to seal it. I found ours had come off/fallen out and was laying on the counter top. It looked like a rubber foot for the coffee machine but there were none missing and I nearly threw it away. Refitting it to the needle cured the leaking problem.
