My washing machine (Zanussi ZWF12070S) recently decided to stop washing half way through, and I'm trying to figure out what's wrong. When the issue occurs, the Start/Pause button flashes red; if I turn the knob to Off and then to any other program, the machine starts, just to stop again after a while (roughly in the Rinse phase).
Having the laundry soaked in water, I tried to just do the "Rinse", and it stopped; I then tried to just run the "Spin" program, and it worked correctly.
At the moment I checked filters and drain, nothing seems to be blocked. I unplugged it for a bit of time and retried, to no avail. After a bit of research, I managed to find an error code, which should be E11 (button flashes Green once, then Red once). This, in my understanding, could mean "problem filling", but I'm not sure where I should start looking. There's plenty of pressure in the pipes (tested), is there anything else I could do before calling someone to service it?
Thanks for the help.
