Baxi Barcelona - problem with overheat/lockout light flashing. Sometimes will work for a few days/weeks without problem - other day’s locks out frequently. I don’t know what changes or makes the difference but something happens!
It’s always done this………
Once its been on for a while and system is up to temp, boiler shuts down as expected, when heat is called for and boiler try’s to light, combustion fan starts, gas value clicks, gas ignites with 'pop' runs to two or three secs then gas valve shuts down, boiler will then try to relight in around 3 mins and most likely starts successfully. But if you turn boiler off with stat immediately after boiler fails to light but turn back on and set the boiler stat to give slightly greater temp/heat it will start up normally.
If anybody has any ideas I’d be interested to hear.
Mine is 1999 vintage with all original PCB’s and loom.
Always been a little troublesome with the following parts but at present these are OK. Water trap clean and empty, combustion door seals new, burner replaced last year. The black and red water out temp components replaced. New electrodes fitted. Combustion space and flue clean.
Any help much appreciated.
