12U ERROR cannot spin , Panasonic Washing Machine?

Hi,

i need help on my panasonic automatic washing machine.

I move to a new house, so i send my washing machine with a lorry.

the problem is, now the WM cannot spin anymore with error code U12 ( or 12U ).

it can wash perfectly, but it will get stuck with the error when the spinning is in the progress...

anyone got any idea what is going on?

thanks everyone
