Hi, My boiler has been woring fine until today. I noticed we had no hot water, checked the boiler and the heating wasn't working either. The boiler sounds like it's running as normal, and diverts to hot water when demanded although it comes out cold. Removed the cover and could see thr flame was out, pressed the auto restart button but it still did not light. The green power button is on, the orange 'flame' light is off, and the red lockout light is off. We did have the diverter valve replaced, but that was over 12 months ago. Looking at the manual I think it could be the hot water flow switch, but don't know much about boilers. There are no leaks and the pressure is constant at 1 bar.
Any advice, please?
