Why Does My Hob Ignition Keep Clicking?

Your hob ignition clicking shouldn't be anything to worry about, as it means that your ignition is working too much if anything. That means that any gas around the hob will be ignited and burned off before it can build up.

Trapped food

There are many potential reasons your hob ignition is clicking, but the most common is that some food or water is causing an obstruction.

Clean the igniter, but be sure to leave the hob dry once done. Too much water will mean that the problem persists, and might have been the cause of the problem in the first place.

Hob Microswitch

If this doesn't fix the problem, check that the microswitch on the hob isn't stuck down. Remove the knob covering it to locate the microswitch. If it is stuck down, and cannot be unstuck very easily, you will need a replacement spark module.

If it's not stuck down, the switch may have shorted. If this is the case, you will need a replacement spark module.

Hob Control Unit

Automatic ignition cookers, where the ignition kicks in automatically when you start the gas flowing, have one more option. It might still be the case that debris, water, or a faulty spark module are your problem, but you may also need a new control unit in some cases.

This is a much less common problem, though, so be sure to check thoroughly for the other potential issues first!
