Hi, We were cleaning our gas hob cooker today (which has an electric ignition) today and perhaps incidentally, since then it has been sparking (making a tick noise & constantly igniting) even though the gas is off. It should only spark when the button is pressed yet it is doing this constantly of its own accord. We have tried turning the switch off at the socket but appears this only turns off the electric cooker below. The only way to stop the cooker sparking is to turn off the entire house electrics at the fuse box. How is it possible to disconnect the ignition of the hob without potentially taking the kitchen to bits (hob & cooker is built into worktop)? We ideally want to simply disconnect the ignition, although would repair it if possible? Has a wire come loose or is there a fault with the connection? Any help much appreciated...
