006430 Genuine Spark Plug Ignition Electrode with 500mm Lead for Blanco Gas Cooktops, Burner Igniter Reference S2

The 006430 is a genuine Blanco spark plug, the ignition electrode that sits beside a gas burner and fires the spark that lights it. It comes with a 500mm lead and carries the reference S2 in its description. We don't hold a model list for 006430, so check the number against your Blanco cooktop's parts list, and compare the lead length and electrode shape with the plug you're replacing.

Gas burner not lighting on a Blanco cooktop

When you push and turn a burner knob, the ignition module sends a high voltage pulse down the lead to the spark plug, which jumps a spark across to the burner cap. If the insulator is cracked, the tip is coated in grease or the lead has broken down, the spark tracks to the wrong place or never reaches the gas. You'll hear clicking with no flame, see a weak spark, or find one burner that only lights with a match while the others work. Cleaning sometimes helps, but a damaged plug needs replacing.

Replacing a cooktop spark plug

Turn off the gas at the isolation valve and switch the cooktop off at the power point or switchboard. The plug usually clips into the burner base from underneath, with its lead running back to the ignition module. Route the new lead the same way as the old one, clear of hot parts and sharp edges. Gas appliance work in Australia should be done by a licensed gas fitter.

Questions about this part

Does the lead length matter?

Yes. The lead has to reach from the burner to the ignition module without stretching, so a lead that's too short won't connect. Measure your old plug's lead and compare it with the 500mm length of this one before ordering.
