Zanussi zwd1471w not working, 'on' light comes on but nothing else?

Yesterday our washer dryer stopped and turned off towards the end of a wash cycle - turned out the fuse in the plug had blown, so we changed it and thought nothing of it. But then the same thing happened today... Only this time we changed the fuse, and when we turned it back on, only the on light would come on - there were no other lights or error messages. My partner drained the water out and checked for blockages but there wasn't much else we could do as it's probably something to do with the electrics...

Any ideas on what the problem might be, and if it might be easy to fix or if it's time for a new machine? Needless to say it's no longer under warranty :(

Thanks!
