Ok ppl,
If this has happened to you then simply undo the two screws holding the control panel in place. Inside on the electronic board you will find a small fuse about 20mm long (small cylindrical thing held at each end by chrome clip). Replace this first, as that is usually the problem. If this doesnt work then you will have to call a tech as it's probably going to be the board.

This solution worked for us and only cost $2 for the fuse from an electrical appliance repair store.
