baxi solo 3 pfl 60 starting problem

[boydeste]

Hi,

My boiler often has a spell where it fires up for a few seconds then the main flame and pilot goes out then immediately fires up again, it can do this for ages. I have noticed that whilst lit the pilot lit indicator flickers on and off which kind of suggests that it is loosing a signal to tell it the pilot is lit. I can't see any thermocouple though or any thing else that detects the pilot flame,

Please help

cheers Stew

Sounds like the 90d elbow off the aps is cracked.

Just had a thought that aps is air pressure switch, I will have a look at this,

Btw is that how the boiler knows that the pilot is lit ?

No mate, it uses flame rectification back down the ign electrode and lead.
