I bought this Cuisinart EM-100 about six months ago. I used it aproximately two or three times a week, and it made wonderful espresso until three weeks ago. I cleaned the machine according to the DVD instructions supplied with it and without any coffee in the basket, the water flowed freely. When I add coffee and the heater light goes out, all I get is the peculiar noise it makes when turning the control knob, but no coffee. One more thing: from the day I started using it, it leaked water on my kitchen counter. Since it was making good coffee, I decided to live with this minor annoyance. I advise any potential buyers to look elsewhere. The Cuisinart EM-100 is a waste of money, and an exercise in frustration.Cuisinart EM-100 1000-Watt 15-Bar Espresso Maker, Stainless Steel
