The ignition on my hob is sparking every second or so constantly on it's own? The knobs don't seem to be stuck down or anything obvious. All four ignition points on the cooking points are visibly sparking.

Hello,
The problem is one(or more) of the 4 switches that turn on the spark when that burner is turned on is shorted and stays closed (on) all the time.To determine which one it is the face where the knobs are has to be removed,with THE POWER OFF a meter set to low ohms rating is used to check each switch by removing the wires to it and see which one has continunity (ZERO OHMS) when its off and that switch that slips on the burner valve shaft is the bad switch(s) and needs to be replaced to keep it from sparking all the time.

I hope this helps you to repair your cooktop,
Gene

Hi,
Here is a tip that I wrote that will help figure out why the burner spark keeps on clicking...

hi gud day,try to clean the area of knobs by using vacium,remove all the knobs firts then clean it,unplug the unit before u clean.

tnx gerbee

You have to turn the knob a little farther, past the light stage. Sometimes they're not marked quite like they should be.

try easing each knob upwards a bit.

There is no fuses, as long as you have a power supply into unit then the only item that can cause this fault is a faulty spark generator.the hob will need to be dismatled to repair, remove the knobs, remove the burners and then remove the obvious screws, top will lift off Regards Advisor

Either one of the ignition switches are stuck down internally or the ignition pack is faulty, no other possible cause. Regards Advisor

Had the same problem. All five burners were continuously igniting, after my wife had given the stove a clean. Turned off the power, removed the five knobs and corresponding rubber rings, and used a hair dryer on the five holes where the knobs were for about ten minutes in total. Hey presto, when I turned the power back on, the constant igniting had stopped. Thank you all. I love the internet :-)

problem with hob is probably water ingress in area of ignition unit - will probably cure itself oven is a completely separate unit from hob. problem with it is that you have to re-set the clock - you have it on automatic. after power outage, oven clock always has to be reset
