We bought this machine and loved it until it was time to descale, the first machine I got would not descale I called customer service we went through the process and nothing. They sent me a new unit two months later time to descale again this one goes through the process shuts down and now won't power back up. it says to descale until the add water light comes on well that never happened. They are sending me another new unit but I will be without a coffee maker for up to 7 days. Love the unit but I guess I won't be descaling it because every time I try the unit breaks.
