SOURCE: Combi bolier problem
either the h/w flow switch or diaphram reqs replacement or the secondary heat ex or (calorifier) is blocked and prevents the heat from leaving the biler to hget to he taps- the heat starts ok but backs up to the boiler very quickly causing it to shut down

SOURCE: Shower goes hot and cold
If you are having trouble only at the one fixture (shower), and no where else, the problem is most likely in the shower valve...which either needs new cartridges, or a complete replacement.
hope this helps

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

You can try to rotate the first plastic ring to the left of center a few teeth, this will let the handle advance alittle more to the hot side.
