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 Fourways Gardens.
This fault is normally treated as same-day work because the site has effectively lost hot water, steam or safe operation.
Fourways Gardens sits within the Fourways belt, with larger stands, long hot water runs and frequent pool heating. Static pressure and dead-leg length are checked as part of any hot water complaint here. Where a site runs on borehole water, hardness and iron content shorten service intervals considerably and are worth testing before setting a maintenance plan.
