I am having trouble establishing myself on the intriguing similarities to EI-EAT, the way I see it, they failed to empty the potable water tank and the aircraft sat for 20 hours at sub-zero temperatures leading to a burst water pipe and damage to the electronics that happen to be in the area. Temperatures don't get that low in Rio, so what is the intriguing similarities?

As
Lonewolf_50 points out, the difference between WRN and WRG is a matter of trust. It is all part of the CMS (Central Maintenance System) and ACARS is part of providing from the aircraft to the ground a dialogue of a detected problem. When the aircraft is then on the ground, the maintenance folks can access (download) system reports from the various onboard computers to get at the problem. for example, They can download and print out a Maintenance Current Flight Report and the messages displayed. if there were an electrical problem, a warning message would be issued, "ELEC A/C Bus 1 Fault" HARD meaning it was permanent. That could then be investigated as a fault message which identifies the source, "Power Supply Interrupt". Then using the Identifier function it can be traced, Seen By: FWC 2 CMC 1

Not if you have a basic understanding of the aircraft systems including Central Maintenance System (CMS). However, the details & status may be hard to obtain when the aircraft is not on the ground but under the sea.
