Unfortunately, the flash is no match for the brightness of the sun, but you can see the switch on the pillar in the middle has melted, the conduit is charred, and the plug is lying, without prongs, on the left.

My best guess is that while performing plumbing work on 14 January, some dam water splashed on the power socket. It has a high salt content, so it would conduct relatively well. The socket is made of plastic, which after charring conducts even better.

We replaced the socket and confirmed that the pump is still OK. I tried to get a ceramic insert, but they don't have that sort of thing. It would be too simple, wouldn't it?
