i take it its an R.C.D nip down bnq buy a new 1 sounds like its fualty be a lot cheaper than calling a sparky out mate and there easy change

ok mate cheers ill get a new one tommorow and turn the electricity off and refit it, cant be that hard cant it. i dont know if its an RCD but ill obviously recognise another one when i see it. thanks

no mate easy peasy change can be a bit awkwark if the wires are a bit short just just make sure your connections are nice and tight and be careful you dont trap any wires when fitting the new 1

ok will do.
