Boiler not heating water

[rowlanda38]

Hi my boiler has stopped heating the water, the pressure is fine just over 2, plenty of money on gas and my gas hobbs work fine, the water pressure is fine, but as you can see from the video it starts uo then at a certain point cuts out and goes up to 99 then to 00

Any help be appreciated

No video attached. Guessing a Combi boiler? What make and model?
