Smeg hob won't light when oven is on?

We have a Smeg suk8 MFX 5 burner cooker which is generally ok, except the hob burners are very reluctant to light when the oven is hot. Once lit, they go out again very easily. Does anyone know if there is there a way to fix this?

you have to replace the thermocouples, a job only for comp eng
