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

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.

Sounds like the pump's not running.

Or diverter valve is stuck in HW mode.
