Gain access to a Aquarius TMC570 dryer?

hi
My dryer is blowing the mains everytime I turn it on. Last time it happened it was under guarantee and it turned out to be a underwire which has got into wiring . I have tried to remove all the back panels butl but cant get it off from rear as tucked under side panels and top panel which I cant get off either? Any ideas before I call a repair man
