I placed the kcup pod in the holder,and closed the lid so the pod would get punctured both top and bottom.
Without going to the next step, I lifted the lid up and removed the pod to see if it was getting punctured.
Well, it was not. The top was fine but not the bottom, which was barely punctured.
So I got a pointy knife (pointy nail works too) and made the hole a tiny bit bigger.
The water can now go thru the pod easier.
This happens on those pods that look like they are overpacked.
The air pressure inside the pods forces the coffee grinds into the water line and clogs up the pins.
I hope I'm naming the parts right and that this fixit is understandable.
