Weird, but it happens..........we always set up our coffeemaker to come on automatically, so we have hot coffee ready right away. Occasionally, the filter will get flopped over in the basket, and when this happens, the basket fills up with hot water, and eventually the hot water/coffee ground mixture overflows all over the counter, floor, etc. Several mornings I have come out ready for a nice hot cup and discovered this. Ugh.
