Greenstar Heatslave II 18/25 won’t re-light

[Auntiedee]

I ran out of oil last night luckily managed to get 140litres delivered earlier but it is showing the same lock out code even after resetting.
I am sure it needs bleeding but after removing the boiler lid I have not got a clue where to start.

Any help would be appreciated. Thank you

Whichever burner is fitted, there will be a hexagonal brass extension from the oil pump. Remove the allen screw from this bar, and see if oil comes out . If not, have plenty of cloth ready and press the reset, but be ready to switch off. Also make sure any filters are bled.
