Hi,
Its been recently serviced so is certainly clean, but probably 1 out of 5 ignition instances fails for both HW and heating (either both or individully on).
If I turn the boiler off for a short period >1 minute, then back on, the burner will then usually light. When the boiler fails to light I do not hear any spark type activity. When it does light I do hear the crack of a spark.
Could there be a pilot light issue?
What else could cause intermittent burner ignition failure? Sensor or thermistor need replacing?
Thanks in advance.
