Zanussi ZWF 1421W power failure

My 14 month old washing machine has no power/no lights on.The fuse is ok and there is power to the capacitor. The drum is empty and machine worked perfectly when last able to use it.

I am reluctant to go any further but would like an idea of what the possible cause of the failure is....?What would be the most likely cause Capacitor?Interlock?Module failure?

I am grateful for any advice.
