HRM Wallstar Oil Boiler - Advice please

[SJB060685]

From what I've seen, heard and read I'm still leaning towards a pump issue. I'm not saying it is but it's what I'd run a couple tests on first. To prove or disprove ignition and atomization things have to be done but I'm not going to say what. It could be air related as well but I'm not convinced.
I cant say anymore, from here on in it needs a decent engineer with good experience and the right gear.

Have you taken the burner out before?

If you have, take it out and take a picture looking down the blast tube. Make sure you unplug coil or turn it all off.

No never taken burner out before. Although I work as a mechanical fitter im not confident with taking burner apart.

No problem, respect somebody who knows there limits.

Was the nozzle changed at the last service?

Whereabouts in the country are you?

 

[SJB060685]

By all means update us if you get a result.

Too far for me. Hope you find somebody to sort it and please let us know what the problem was.

Yeah sure will. Hopefully if I get sorted I’ll be able to pass on my fix to someone else.

Fool the photocell into seeing light once burner fires and see if burner continues to fire while photocell out. Handy on Sterling burners.
That will prove flame is poor for some reason or photocell had obstructed view.
Does sound like flame burn is barely making it

Boiler started up 1st attempt this morning.......

I did try this awhile ago. I think when I removed photocell burner continued running but when I covered photocell it shutdown if my memory serves me correctly.

Took burner unit off and had a look. I’ve attached photos. Tip of nozzle is damp with oil.
Any suggestions?
