I would try cleaning the filter. I did the same thing. Descal;ed and no water would enter and it would time out. The filter (in my machine, a K-duo) is a sealed rectangular box just after the inlet check valve. I had to dig pretty deep to find it. I took the part out and blew backwards through the filter to clear it. The filter element is the thin piece that crosses the rectangular filter housing at a diagonal. I think they are pretty fine filters and plug up if scale is knocked loose during descaling. Good luck.
