I just came across this for a model CB24. The one that I was told about is a CB25, but may be similar.

The "he" bit in the name means high efficiency, it is a condensing boiler and newer than that one in the vid, so not the same. Did you find the he cb 25 instructions? You can get a fair way through fault finding as an electrician before doing gas "work".


Not sure whether ebee's air pressure switch fault would be picked up in a flow chart, it is very unusual to have continuity through all 3 terminals
