Zanussi ZDS100 keeps draining, then stops with error

Hello,

Hope you’re all doing well. I come here in desperation! 🙁
My dishwasher turns on, immediatelly starts draining, and after some 3 minutes of doing it, stops and the Cancel LED starts blinking. After that, the finish program LED flashes red two times every once in a while. The finish program LED is the third one (last one in a column).

I’ve opened the machine and tested the pressure switches with a multimeter and they make continuity when I blow into them, so it seems to me they’re fine.

I’m out of clues, perhaps any of you gentlemen know what the issue is? :rolls:

Cheers!
