Fault code on washing machine

I have a Zanussi ZWC1300W washing machine on which the End programme light flashes 5 times, nothing else works. I called out an engineer who said the code meant 'no data' and I would need a new circuit board which would cost £270!!!! Is this correct and could I buy the circuit board myself cheaper and fit it as I am quite competant and have already replaced the belt on the machine? It is only 3 years old and has been used for 2 years as it was stored for one year. It seems a pity to scrap it.
