Has anyone repaired a gas boiler where the rads. heat up but the hot water is not running properly from taps.
The boiler is an Alpha HECB25. All the electrics seem fine.

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

Z.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 terminalsHello Olympus,
I have been so busy that I have not had a chance to get the fault finding flow chart yet. I did though order a new diverter valve diaphragm repair kit. It is suitable for the Alpha HE 25 and CB33 according to the supplier. It looks the same as the one in the video, and it comes with many new washers and some silicon grease. I may check the micro switch if it is accessible, before any dismantling.Zoomy, admit it, you just like fixing things. ?
Gor blimey mate. It's a fair cop gov.
