Our Siemens S16-39 washing machine started to display F18 and beeping (not the normal 'finished' beep).
We switched it off. Googling suggested that the impeller was broken/unable to move.
Switching back on made a straining noise - switched it off again.
I turned the large pipe (front right bottom) through ninety degrees.
Switched back on, turned to Empty. No bad noise and emptying started.
When empty I placed a towel under outlet and completely undid the large pipe.
There was human hair, a shirt stiffener and piece of slate, removed these and all well!
