I have a Bosch 26CDi XTRA, I tried to change the on and off times for the central heating settings, this I think I achieved however the water will not heat for the shower or taps and the reset light is flashing. It also looks like the system will not fire up although I get all the right noises? Any ideas as I can't go back to the point before I started mucking about even though timings were wrong but at least I had heat and hot water. If you know the answer please email me on [email protected]. Thanks.
