Can anybody help? I have a worcester bosch 24cdi boiler. The central heating works fine. The hot water however only works with the central heating on, but the hot water demand light still doesn't come on.
The diaphragm kit is cheap but access to the diverter valve is poor.If there is good access underneath the boiler then it can be done in approx
1 maybe 1.5 hrs.Best get someone who has done this B4.
