Good evening my name is ***** ***** I will assist with your query today.
Can you confirm if the fault is on all burners or just one, and if you can smell gas after holding down the knob for 10 seconds?
The most likely cause the burner is not correctly positioned or is wet.
Remove all the burners inspect them, make sure they are dry
Refit the burners, then try each one again in turn.
If that does work, find a lighter or match hold the flame next to the small burner and try and turn the knob on full heat and hold it down, and see if you can light the burner with the flame from the match\lighter.
If it still doesnt light try it on the other 3 burners, but please use caution so not to burn yourself, as the burners should light quickly.
Should none of the burners light this would suggest a gas fault, since holding a flame next to the burner bypasses the spark generator.
The last time it was previously working (eg yesterday), did you have a spillage or something boil over, as its looking like either all the jets have become blocked or the valve has failed.
Its unusual for all four burners to be affected, especially days later.
The last thing I can suggest as a consumer, would be to remove the burners again, and poke some wire into the jets located under the burners, and give it a good poke about. I recommend using something like a paper clip, turn on the jets (one at a time) and see if you can feel the gas rush out with your finger.
Replace the burners, and try and light them again, if this doesnt work you will need a fast safe engineer to attend and strip the hob down, I dont think its anything mechanical failing if you can hear gas, and the sparking, its most likely just too little throughput of gas.
Good evening, I havent heard back from you in the last few days, do you still require assistance?
