Gorenje Gas Hob Ignition Problem

[AlGBarker]

Hi all,

I had a kitchen put in about 18 months ago with a Gorenje four burner gas hob.

I noticed today that the ignition on the wok burner has decided to stop sparking, but the other three are still sparking fine.

Nothing has come loose nor does anthing appear damaged or different. I've also given it a good scrub to make sure there is no dirt which might be the cause but still nothing.

Any ideas why or how to sort the problem?

Thanks, Alan
