Welcome to our forum.
It's very odd but I'm worried the previous owner just sunk it in the cement and didn't think to plan for repairs or having access to the insides.
The equipment is under those areas under your compressor and the other side. There has to be a way to get inside those two corners. Does the entire panel come off, tiles and all?
Use an inspection cam along the edge or even down the air control openings. Minimal damage to that beautiful tile.

I just feel fairly certain now that they were stupid and buried it in the cement with the pumps and everything. If they did, I don't know how I could easily pull it out to repair it without breaking it more in the process.
