Not sure of age, came with the house - serviced for first time (by us) December and failed on some sort of leaking gas/fumes issue but was fixed. Engineer said otherwise it was “perfect”
I think it is not a combi (we have a water tank).
All fine until yesterday suddenly not igniting - but seems to be trying to ignite
May be obvious but don’t have much of a clue about boilers - any ideas of anything I could try (apart from reset) before having to call engineer again?
Or what the problem could be so soon to the last service?
