Our coffeemaker has miraculously come back to life. I started thinking about how it was just seven months old, and that it shouldn't break so soon, even with almost daily use.
So I cleaned it with a vinegar and water mix and rinsed it through a second time, and it worked fine. I tried it with coffee on Tuesday morning and yippee-skippee it brewed a pot. I've been happy ever since.
I think I may have clogged it up by adding a bit too much cinnamon to the grounds one day, and it rebelled. Just a theory.
