Hi,
I have a Vaillant Turbomax 828e which is 3 years old and today I do not have any hot water or heating. There are no lights on at all ( red, yellow or green) although the green one sometimes comes on and flickers on and off. The pressure is okay as I was taught by the guy who installed it how to do it. Going through the manual, there are no F codes and the diagnostics says S23. Any help would be greatly appreciated as it is frrezing cold in Cumbria.
Thanks
