electronic ignition sparks on all 4 burners and then eventually stops.

Hi Diane, Thank you for your question. First things first is that you should never put wet pans on your gas cook top. The water can drip down into the sparking mechanism and damage it. This could become a costly repair. What I would try first is shut the power off to the unit for AT LEAST 48 hours to allow it sufficient time to completely dry. Do not use wet pans anymore and see if you still have the same problem. Pleas let us know and we will go from there.
Thank You, Tony-AceTech52
