It’s a system boiler, so I would have thought it would only react to a demand?
demand for heating and water is on.

And have the switch live wires been tested to ensure correct operation?
Swiwched lives are there. Could it be a pcb issue as there is no display?

It could be, but it lights up, so not definite. Have you tested at the boiler end to make sure it’s receiving approx 240vac? Have you checked for any loose wires? Are you GS registered?
240 at the pcb. Cant see any loose connections. I am not GS
240V at pcb. Cant see any loose connections. I am not GS registered.

Likelihood to be pcb or display pcb, removing the cover on that boiler forms part of the combustion circuit and should only be worked on by qualified gsr engineers.
Could quite possibly be the PCB time for a engineer 😉.
From memory a 330 is a re badged Valliant boiler? these suffer from PCB problems with age there's a interface board and a main PCB so it needs be determined what's happening here ?
