does anyone know of a reason why when running the hot water after a short while the boiler cuts out and the water runs cold? the water pressure seems to be ok the water just runs cold.
i would say that the minimum gas pressure setting has gone off. should be set to 1.9mbar for minimum 10.1 for maximum vokera boilers call out is £149 plus vat any parts needed.

could be heat exchanger but more than likely it'll just be the thermistor on hw outlet from exchanger. thermistor is probably out and not telling the boiler to modulate burner down and allowing boiler to trip out on overheat hence the hot cold hot cold
