on/off boiler light and clicking on baxi solo 3 pfl 60

[freestyle]

Hello.

Firstly thank you in advance. You are always really helpful.

So my boiler is clicking on and off. I've lifted the front panel off ONLY, and there are a series of lights.

The overheating light is OFF
everything else is on

The boiler light goes on and off constantly every 3 seconds. This matches the visible ignition in the pilot window.

Is this normal ?
What could be the problem is there is one ?

Yes, pretty normal , it happens every time the pcb fails!

But it could also be eg problems with the fan pressue switch/tubes etc. A corgi job - fan and burner pressures need testing too.

Some of these were supplied with a faulty batch of elbows on the aps that cracked causing these symptons.
