Rosieres Paul Bocuse Double Range Oven (2040)

Our old Rosieres oven has blown another heating element in the left hand fan oven and despite getting a replacement online and checking that it works ok have not been able to reconnect it successfully (as it keeps tripping the RCD) and a friend with Voltage tester has checked it out and can’t find an obvious solution – maybe the switch has blown? He suggested I ask if anyone out there might have access to a wiring diagram or service manual (online seacrhes have brought me no success other than to here.

Can anyone suggest ways forward that won’t cost the earth? – better still, that allow me to replace the element accurately myself (simply replacing what I thought were the wires to the relevant connections HASN’T worked!!).

Any pointers would be gratefully received – and will make my wife VERY happy (haven’t managed that for some time!!)

Thanks in the hope that someone out there knows some answers.
