Whirlpool ADG 7550 error code 11 flashes

Hi

First of all what an excellent forum. I’ve searched and read much already about our dishwasher and it’s problems.

At the moment ours is flicking from the 50o program after a minute or so and beeping constantly. Error code is 11 flashing lights which I “think” from a guide I found elsewhere to be FB Motorised diverter valve.

Could anyone please confirm the fault code for me and advise whether the part is replaceable, easy for someone ok with electrics and DIY to find fit and most importantly where I can source a part from (or fix if able to without the need for a new part!).

EDIT Seems I may have been wrong another guide found suggest an OWI
optical water indicator error. Not sure where this is though or if my machine even has one. :/

Thanks for all your time, appreciated.
