i have been having a few problems with my vaillant turbomax pro

the heating and water works fine for a bit then the ignition indicator flashes
i have looked in the booklet that came with the boiler and it says a flashing indicator shows lack of water or poor water circulation in central heating system,

but the preasure gage reads a good 1.5-2bar


any help would be greatly welcome

thanks

I have exactly the same problem in that the boiler seems to be working fine, all the radiators are working well and the pressure is in the correct range. I have noticed that the problem gets worse and worse as the external temperature decreases. I think I have a boiler that doesn't like cold water. Can someone from Vaillant please help!
