Thanks Mike, first make sure the unit is getting water make sure the valve is ON. If so this one needs a new main control board.
Its easy to fix if they still carry this part, considering its age, they may not have a new board for this model.
But the best place to check for that would be this site: http://www.ransomspares.co.uk/
They usually ship the same day you call, and I recommend you give them a call to check on availability of this part.

There is no soldering needed, it simply plugs in once you open the door cover;-)
I will help you all the way if the part is available and you choose to fix this one.
Just please let me know on that?
In any case, I will stick with you until this is complete.
