SOURCE: hi,i have a vaillant turbomax
Which turbomax, as there a two different models. The more modern one, with the brass CPL diverter valve, located at the front left of the boiler, was very prone sticking & jamming, this would restrict flow through the hot water circuit in the boiler, and cause cycling. Vaillant actually modified the diverter. You can identify, if it is the old type, as there is a very small hole in the middle of the diverter on the old ones, probable no more than 1mm-2mm wide. The modfied one, is much bigger approx 5mm wide. If old type, replace as this usally sorts the problem

it is either your pump is not running or blocked [ debris from installation ect ] or your diverter valve is stuck partially open allowing a little water to pass into the heating system [ usually first rads on system ] it runs for a short while and cuts out because your overheat stat is kicking in because of poor circulation [ it is only running around the primarys in the boiler where it quickly reaches the over heat limit ] temp tends to rise approx 1 deg per second a clear indication of circulation problems.
