Gas Boiler Not Igniting in Paulshof
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 Paulshof.
This fault is normally treated as same-day work because the site has effectively lost hot water, steam or safe operation.
Paulshof 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. Gauteng municipal water is moderately hard, so scale on elements and heat exchangers is the single most common cause of falling performance.

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.
