Many thanks all for the info.
Ok, so I finally just got around to pulling the water heater out of the MH and this is what I found... see attached.
Yes, signs of an electrical fire. As this was only our 2nd trip when the electrical side of the water heater stopped working and the MH being a 2015, fire was in a sealed bay away from rodents etc. I put the cause purely at the feet of the installer/manufacturer.
Sorry mixed emotions at the moment, the fire was only inches away from the gas supply line... so, lucky and grateful that my wife and I plus the grand kids are still alive but really pissed off at the same time.
From the replies, this is far from an isolated incident. I have to ask myself "is this intentional" we're talking 3 wire's, no more difficult than wiring a lamp plug. And in the 27.1 there seems to be no safety cut off (breaker/fuse), nothing tripped. The only reason I can think of that the fire didn't spread was that it ran out of oxygen and/or the heat actually twisted/bend the shorting wires apart.
I hope (without much confidence) that someone at Thor actually reads these Forums and takes positive action to remedy these possible life threatening practices/procedures.
