It was a normal descaling process, but after the descaling solution was through, I filled the tank with fresh water and then started the rinse cycle, which ran without end. After 5 tanks I unplugged the machine and waited 2 hours, after plugging it in it started again without stopping. I opened the machine, opened the flow meter, checked and closed it. The machine started after a further rinse time, normal mode appeared on the display and I selected the coffee button. The machine ground the beans, but when I started the pump, no coffee came out, but pure water came through the bottom openings.
Who knows what to do about this?
