Oil boiler trying to fire up and grinding noise

[Inverness]

I did bleed the oil with my oil guage device.

Maybe replace the oil pump first?

The boiler does not go to lock out it just keeps on working trying to fire up the initial start up and continues doing this...

Riello oil pumps can have their drive pin and first gear broken/worn and will slip and suddenly stop pumping oil. That is easy to check by opening the oil pump outer cover and then removing the inner gear cover (keeping gears pointing upwards or they will fall out rendering pump useless) and see if drive is broke.
You will need bearing pullers, small socket set (think 5.5mm socket for Riello motor bolts to get at bearings)
Fan puller advisable, but is possible to remove fans by turning them rather than pulling them, while stopping other end of motor turning.

If your Riello pump looks like this, then it is knackered.

Photocell could be dirty

Photocell clean. Wow thank you for showing the inside of a broken oil pump. If I open it up and check if it is broken I'll just get a new one replaced. But your saying if the cogs are like this you can easily fix it as new again?

No, you can’t fix that Riello oil pump in photo. The drive pin is broken and the gear will have been cut into by the pin, hence why the pin is not inline with the cut outs in the first gear.
Some pumps can be occasionally repaired if their pin simply wears though, - like Danfoss.

They just have 2 or 3 adjustable arms with bent ends that hook below the bearing and a threaded bolt in middle to screw downwards to force bearing up off. No point in spending too much on one, just get a basic one
