washing machine Hotpoint WMT03 does not start (no lights, nothing)?

Hi, my washing machine does not start, the lights are off, nothing happens. I checked the wall socket and the plug's fuse, they are all fine, still nothing.
About one year ago it wouldn't start, but then the red light was still going on, I then managed to fix it myself by changing the door interlock.
This time there is no lights going on though. What could it be?
