How can i fix my stelrad ideal classic nf40 41 429 31?

I woke up this morning to put the heating on, only to find there was no piolite light, tried to use the panel to fix this but the panel does not work either. It is stuck on off and will not change even if i press the overide buttons.

I have tried following the instructions to relight but this has not worked.
