I had the same problem .Turn the cooker off so that it stops sparking or switch the main electricity off . Then clean the ignitors .Take off the cooker knobs and check for any debris there.Clean it ,hover it .It should hopefully sort out the problem .I had the same problem .In one of the knobs after removing it , some rice are other stuff was in there causing all the problem.Once cleared all was fine.I hope this helps.Make sure it is off when you clean the ignitors.
