Riello RDB boiler not firing

Hi, I'm new to this forum so please feel free to redirect me if I'm in the wrong place! I have a Riello RDB oil boiler which is simply not firing up at all. I am due an oil delivery but we are not empty so that shouldn't be the cause. The lights are all on but there is no sound at all. There appears to be a small water leak from a black fixture dripping onto the heat exchanger (shown in second image), we had someone out and the heat exchanger replaced less than a year ago for the same thing. Whilst I am happy to call someone out if needed I was wondering if there might be anything obvious worth considering or checking first?

​​​​Any advice at all would be really appreciated, thank you.

Riello RDB is only the burner that that particular boiler uses. The boiler is a Warmflow and is pretty much an exclusive UK boiler. Sorry I know nothing about them.

This looks to be an Asian- or European-style wall-hanging boiler? You will need to call a factory-authorized repair person to deal with the proprietary technology. This is a DIY forum, and most of us are located in North America, and unfamiliar with wall-hangers.
