My boiler will not fire up from the programmer when set to timed, but if I press the advance button on the programmer it starts the ignition sequence and the electrodes spark but the gas does not light. yet if I immediately press advance again the sequence restarts and is always successful.
So the system works but wont start from program, only from manual.
The programmer has been replaced with a Drayton Lifestyle 522 which is a straightforward swap from the old unit and the old motorised valve has been replaced again with its new equivalent.
Is the ignition spark too weak?
Is there not enough gas in the chamber for the first ignition attempt?
