No Central Heating Worcester Bosch 280

[Paul Howls]

Hi,

We're getting hot water but no central heating on our Worcester Bosch

280.

When put on Heating & Hot Water and the timer set to have the heating on - the fans run but the boiler only fires occasionally (possibly just heating the water in the internal tank). There is no sound of water going through the system and the pipes are cold.

The water pressure is at about 1 bar - which is just below the red marker.

Has anyone got any ideas what's wrong? or knows how to increase the pressure incase that's the reason?

Thanks.

Paul

Sounds like the pump's not running.

Or diverter valve is stuck in HW mode.
