The boiler attempts to start, clicks or purges, then locks out without lighting. This page covers how we diagnose and repair it on boilers in Lone Hill East.
This fault is normally treated as same-day work because the site has effectively lost hot water, steam or safe operation.
Lone Hill East is a high-value residential pocket of Fourways, typically with multiple geysers or a heat pump on buffer storage, and in many cases pool or underfloor heating on the same plantroom. Where a site runs on borehole water, hardness and iron content shorten service intervals considerably and are worth testing before setting a maintenance plan.

The usual causes are failed ignition electrode or transformer, no gas supply or closed valve, gas solenoid or valve failure, air pressure switch not proving. Which one it is can only be confirmed by measurement, not by symptom alone.
How do you diagnose it?
Electrode gap and spark test; Gas pressure measurement at the train; Air proving switch continuity test; Flue and condensate path inspection. The readings are recorded so the repair decision is based on data.
Can I keep using the system in the meantime?
No — isolate the plant and call 069 268 0988. Running it in this condition risks further damage or an unsafe situation.
