Lets not forget that this is an electricians forum for electricians, I do see a lot of blatant diyers coming on here trying to find out why their rcd is tripping etc, thats not what this forum is all about, why should people who have spent a long time learning their trade dispense advice to those who haven't got a clue and are just trying to fix for free. Try going down to your local main dealer and trying the same, their advice would be to book it in to get it looked at by a professional
so like I said if you don't like the question just ignor it
