Leisure rangemaster 110 ignitors not working for hob, grill or ovens?

Hi, just wondering if anyone can help. I have a rangemaster 110 gas, and like the question header says, the ignitor isn't working for anything. I've aleready done the two blue wire trick, and everything has working spot on since, but then this suddenly happens.

I'm able to light the hobs and grill with a match, but the ovens won't even fire up using that method. Any clues as to how to fix? Any help greatfully appreciated
