What country is this in? In the US, all EV’s have an 8 year/ 120k mile warranty or more on the motor(s) and battery.

It needs to be shouted from the rooftops: “Wall mounted EVSE’s must be hardwired!”

I also feel that a lawsuit should be filed against the receptacle manufacturer. The cheap Leviton receptacles fail in this manner in a short timeframe. It’s happened to you, it’s happened to me.

Portable EVSE’s get a pass since they are plugged in and out frequently. The connection points can be inspected for damage when routinely unplugged. They also typically have a temperature sensor in the plug.

I used to drive fast through puddles deeper than this for fun. I say, walk out your path to shallow water, and drive it out.
