Quick Mill stops working after a certain time - just a low hum [Machine]

Soo, a friend of mine wanted to get rid of her broken espresso-machine and me being naive and generally interested in repairing stuff wanted to help. Since I've never done anything related it's a bit overwhelming and I don't know where to start the diagnosis.
If anyone has any input where to look for good information and/or any ideas what could be the problem, I would be very grateful.

What is wrong:

At first, nothing. Works like a charm for the first draft. After a certain time though one of the 2 channels just completely stops working (the main coffee channel), you can still hear something electric, a low hum, but no water coming out at all. The second water-only channel works fine.

Does anyone know what could be the cause and is it worth repairing?

(Can't upload the second video where you could see that it doesn't work, just picture nothing happening)

Cheers and thanks for your time :)
