What happened to your machine?
At first we thought ours was toast. It made a noise like it was pumping for 3 seconds, then would shut off.
I googled the issue. Turns out line was plugged. I used a paper clip to poke it up in the spout end, turned upside down, (and a few spanks on the bottom) and then ran some vinegar solution through it [80/20 vinegar/water]
It's been about 3 years since I did that. Every six months, we clean it inside.
We have the permanent filter and the cup that holds it. Fast & HOT tea, coffee, cocoa, etc!
