Report "I have a 12-cup DCC-1200 black & chrome Cuisinart coffee maker, like the one pictured below. Once every three weeks or so the brewing function goes into overdrive and, instead of brewing a pot of coffee, just keeps gurggling away frantically and, when it finally stops, the "coffee" produced is WAY too strong. I have in the past then used the self-cleaning function and, after a while, it's cleared up. But now it isn't. What to do?"
