SAMSUNG DW50K4050BB does not take in water. ⇐ Samsung

[Iron]

Hello!

SAMSUNG DW50K4050BB has stopped taking in water. It was showing an error in water supply. I took it apart and checked it with an aquastop multimeter. The aquastop on the bottom works, the aquastop on the hose shows 1 on the resistance. The aquastop valve is not pressed, that is, it seems that there was no activation, but it does not drive water. The machine was rarely used, just over a year. Over the entire period it was used no more than 15 times. Questions:
1) Is the problem really in the aquastop or could it be in some other unit, how can you check?
2) I searched the entire Internet, there are no Samsung hoses with aquastop, is it possible to use a universal analogue or from a dishwasher from another company. Or from a washing machine, I don’t know
whether they are compatible?
3) Where can you buy hoses with aquastop, maybe there are trusted stores with universal hoses?

In advance thanks for answers.
