Have you checked the obvious...fuse in plug...If the fuse is intact,then you will need a multimeter to meter the components.Basically you need to find out where the power stops.Start at the uf start capacitor and work through upto the pcb with the start button attached.If you find that these components and their wiring are ok,then the main control pcb will most likely faild.This pcb/display are expensive components to replace.The most common component failure is the start button pcb as I have mentioned to test.You will have to remove the facia to access this.The main pcb (brain) as I have mentioned seldom fails due to electronic failure.Most cases are a short circuit caused by other issues.So make sure that everything else checks out before you fit a replacement.
