Hey I JUST fixed this now on mine.
I fixed it by bypassing(joined the white and yellow wire) the trip out switch which is located under the control module(one screw to remove).Now it Works.
Just unscrew the main bit with all the buttons. Then take the wire plug out of the control, un screw the control panel, and underneath is a white and yellow wire, cut them and mend them together and it will work again.
It's something to do with the out of balance scheme, it gets corroded so just do what i said and it will work, keep what you cut just incase you might need it again.
