Beko DRCS68W trips my RCD when switched on?

I've taken the top off and had a quick look but I'm no sparky (or hero). There are two connectors attached to the main switch, one has a brown wire and an orange wire coming out of it. This is the one that's causing the problem. Can I tell from that what has failed and whether it can be economically repaired? i.e. for less than £200, for which I can get a new one!
