i have a gas boiler that ignites for about 10 seconds then cuts out refires again for another 10 seconds then cuts out again it tries to fire again doesnt and then goes to reset could it be the electrode which sparks the boiler
not sure on these but faults like that tend to point to a flame recognition problem, the boiler thinks that there is not a flame present so cuts off gas and trys again, usually 3 or 5 attempts then will lock out as a safety precaution.
like i said its a long time since ive worked on one of them so cant remember off top of head but id look for something of a flame rec problem, some have seperate rec sensors some use the earth route,
