Boiler not heating up

[Hd7225]

Hi,
We have a logic plus h18 boiler,
Its not heating up, restarted it, i can hear it but no heat. It stays at zero, when i change dial to any degrees it flashes radiator symbol and goes back to zero.
Its about 2 years old
Has anyone got any advice or anything you can recommend as we dont really want somone coming in house to look, so thought would see if any one can help before that.,

Thanks.

I thought 0 on the ideals is standby, so not receiving a signal from external controls?

O is standby on logics not o o as far as I'm aware that's a code that's not on list nearest would be C O which is a board starting fault

Should have said assuming boiler has been serviced it's still under warrant.

It’s not receiving a signal to fire up, check thermostats and zone valves, is the pump running?
