What can cause an oil boilers burner to lockout?

A burner lockout could be as a result of no oil or a leak in the pipeline. Another cause of burner lockout is from contaminated oil. This contamination could be from:- Water ingress into the tank from a missing cover, a damaged tank from condensation, sludge, which can occur due to the growth of micro-organisms at the water fuel interface in the tank or rust from a metal oil tank corroding.
