Hi i woke up xmas morning with no power at all after checking each fuse on the main box it seems that there is a problem with certain wall sockets and the fridge and dishwasher although they now work if they are plugged into an extension lead in to a wall socket that does work.i am wondering if the fuse could be blown in the main fuse box that isolates these wall sockets as i am having to leave it switched off if not the whole thing trips.But there does not seem to be any way of taking these main fuses out!
