I found that the round-shaped filter “spout piece” inside the tank has clogged, far too many occasions I would dare to admit. Letting straight vinegar sit in the tank overnight helped the situation. After a couple of years, I’ve grown tired of this process so I actually grabbed a knife and popped that thing out. Coffee flows normal, however it’s not being filtered (shouldn’t be a problem if you don’t spill the ground coffee when preparing it). I tried going online looking for that little spout part with no luck. You can buy the entire tank part for $20, but really? All I need is to replace this tiny spout (strainer/filter) piece. All in all, the actual piece I removed looks like it was painted with black ink, impossible for anything to filter out through this anymore. I would submit pictures, but I don’t see how I could do that.
