The error code appeard toward the end of a washing cycle. I turned machine off at mains then turned on. E13 vanished. As it looked like there could be water in the machine I selected rinse/spin cycle. It performed OK but error E13 appeared at the end. I have been able to removed my washing and it did rinse/spin.

just a thought, but why not do a Google search for, oh, say "neff washer-dryer V6320X0GB/01 error e13"
