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 Magaliessig Ext.
This fault is normally treated as same-day work because the site has effectively lost hot water, steam or safe operation.
Magaliessig Ext is an extension of Fourways with a mix of original and renovated housing, so geyser positions, pressure control and pipework standards vary stand to stand. Sites with long, poorly insulated pipework lose more heat in distribution than most owners expect, which reads as a capacity problem at the outlet.
