Query: Disappointment

We have had this product for several months now and are very disappointed in it. It apparently has a flaw which makes it overflow all over the counter at times - - some kind of block prevents the coffee from going into the carafe. Thinking we did something wrong, we cleaned it, checked the function on the carafe and hoped for the best. I just went out in the kitchen and once again - - coffee spilling all over the counter.It is disappointing that it doesn't work properly and actually quite dangerous when you have it spilling all over the kitchen counter and floors while being plugged in.
