Gas hob igniters keeps sparking

[Pingwing]

Hello.All of the gas igniters on my Bosch hob continue to spark after one ring is alight. Have you any ideas how I can stop this. Thanks.

if it is a push button ignitor it is possibly jamming, remove the cap and see if you can lub it

Hello. The igniter sparks when the knob is turned to turn on the gas rather than pushing a button.

Does this happen when you use one ring inparticular by chance ? had similar happen on mine and it was the micro switch at fault on that ring! hope that helps
