Miele W1 Classic seems broken with message UP-

Hi everyone, As the title says our Miele W1 Classic seems broken with the message UP- being shown on the display. I found another post saying it is an update and to press the start button but the controls are completely dark except for this message. Does anyone know why or what this is? Thank you.

Update: The problem was fixed. How is a bit unclear though. We opened up the top and removed the circuit board behind the display without unplugging it, wiggled all visible plugs and performed some percussive maintenance on all other visible electronic boxes. We then reassembled it and the display worked normally but the touchscreen didn’t. Apparently because we accidentally unplugged it so we opened it again and fixed the ribbon cable. Now everything works better than before with full touchscreen functionality that (which was only partial and spotty before. Also there was some slight corrosion on the top left side of the board next to the detergent drawer thingy, seems like a constructional oversight since there is no protection against spills at all.

Wanted to post it here anyway as a duplicate of my r/Miele post since I couldn’t find anything on this and maybe someone with the same problem will find this.
