My boiler had a problem with the ignition. The insulation had come off the wire to the sparker and it sparked before it got to the igniter. So the boiler shut down after attempting to ignite the boiler for few seconds. I fixed this by repacing the wire and it worked well for a hour or two but now it wont even attempt to ignite the flame. The 'demand' light comes on and also the 'water heating light' and the little fan but no attempt is made to light the flame. Any ideas anyone?
Cheers.

i presume that you used the correct cable if so can you hear it sparking if you can it is shorting to the boiler so check along the cable if you can't hear it check the spark generator it is high tension voltage so any crack or fault will cause it to short
