Heatline Vizo 24 boiler - central heating but no hot water (Croydon area)

[Chris_P]

I've just moved in to a property with a Heatline Vizo 24. Within two days it's stopped supplying hot water. As the flame ignites and the temperature of the water starts to rise, the LED that advises to check the CH sensor lights up and the flame extinguishes. It then ignites itself again and the cycle continues. I've researched the problem but cannot find a solution and need it looked at. Thanks, Chris
