Had a spillage of water on lid of Hoover dst10166pgbc. Thought I had dried it all off but some had seeped inside. I heard an electric blowing noise and when I had a look the fuse had blown. Opened the top cover and dried where was wet (rear right hand side, not the invertor the bit lower down) and had the hairdrier on it for half an hour. Relaced the fuse and switched back on, fuse held and 230v at the incoming terminals of the invertor, but no displwy on screen and doesnt seem to switch on, any ideas?
