Grateful for any pointers.
My Baxo Solo 2 PF 80 boiler for some time has taken a long while to fire up. Today it hasn't made it :-(
It seems it does not readily establish a solid pilot flame. 3 out of the 4 lights come on, the piezo cycles and I see it sparking. The pilot flame flicks and licks and occasionally becomes substantial enough for the main valve to open for the merest fraction of a second, long enough for the piezo to stop (perhaps just missing a single click), the burner on light blinks and the main valve shuts.
It has been taking 5-10 mins to light properly once the main burner gets a decent chance. Then the boiler seems to cycle OK as its thermostat shuts it down and then starts it up. But once cold, it has trouble again.
A new gas valve was fitted 18 months ago in an attempt to cure this behaviour, the Corgi engineer experienced with Baxi (or so he claimed) citing common problems with its diaphragm. All I could say is that the problem eased for a while, but was never "cured", to the extent that the boiler would reliable start with the first few piezo clicks.
What do you reckon is the troublesome part?
TIA
