After three months, the advise: Descale your pot lit up. So I followed the directions and apparently it was too much for the overload reset in the maker. I called and almost effortlessly Keurig shipped me a new one. Recommend that they advise that when descaling you only do 1/2 of the water container at a time, not to overheat the unit. One negative, if you only want hot water, good luck as we always get some coffee grounds in a cup of hot water. Other than that, great product.
The new Keurig Coffeemaker is now our favorite! We created a coffee station for it, and everything is just the way we want it! This company has the best customer service of any we have ever experienced.
