Baxi Solo 3 PF has intermittent fault in that it starts and runs for a short period but will shut down and then immediatly start up again.
When runnign the "boiler on" "fan run" "pilot on" "burner on" indicators show.
When it shuts down the "boiler on" and "fan run" lights stay on. It sits like this for a few seconds and then the "pilot" and "burner" lights come on and the boiler runs again
Any help or indication of the problem greatly appreciated.
It sounds like it is shutting on flame sensor failure. Check the burners to see if they are stopped up. Check to see if the flames are blowing away from the pilot /flame sensor when the burners fire. If so disconnect the blower and try again. If it stays lit with the blower disconnected, the heat exchanger is probably cracked alowing air to enter the combustion chmber.Â
