I came home last night to a Combi Boiler that will not "ignite" if thats the right term. I can here it clicking but there is no spark, not sure if its the electrodes that need replacing? How can I tell. I have taken the front panel off and looked at the electrodes they both seem ok, not corroded (in my opinion, but I have not got any thing to compare them against)and the gap seems reasonible (no more than 4mm).
Please help.
