K-Duo Flashing Descale Light, but won’t take up water/warm up

My K-Duo descale/fill water light started flashing today. Reservoir is full. When I press the cup or pot buttons, they turn the machine on but it will not start warming up and pull water. I try to press any size cup/pot but nothing happens and those buttons won’t light up. I’ve tried unplugging/replugging it in, holding every combination of size (8oz + 10oz, etc), and emptying the reservoir. The machine won’t start up, so i can’t even attempt to descale.
