Does it start heating the water , hot water or heating . you may have to feel the pipes out

I presume it starts to heat but as I explained earlier it cuts out before it becomes very hot

Expert:  Plumberpro replied 2 years ago.
OK . I think your fault is either the flame recognition device or one of the temperature stats . if the boilervlights then goes out almost straight away it will be the flame recognition probe ( ionisation probe) or if it run a little bit. It is most likely the temperature stats. These are where I would start , as they are the most common components to break down and relatively inexpensive. However it is quite a complicated boiler and I can see why your plumber ran away.
