How do I reset the computer board of my Indesit WIXL143S washing machine?

I switched on a lamp and it blew the downstairs electrical circuit, since then I have had to leave my washing machine switched off otherwise it flashes the lights and makes the noise of when you first start up a programme but its not filling up with water nor is the drum moving. I have done and load of washing and the programme works fine in this respect.
