    Well I solved the issue myself, but thought I would post for anyone else with similar issues. The drum bearing are shot causing the drum to touch the (new) heater and cut through it, causing the earth leakage when its full of water. So now I am up for another new heater plus drum bearings (around $250 total) and a half day to strip it all down and replace the bearings, assuming the bearing holders are still OK. For $629 I can buy a new one…. Wife said buy a new one.

    Hmm… Just checked the new heating element whilst the drum is still full of water and with the element disconnected its showing 28 ohms through the element – perfect, but now 180k ohms one side to earth and 220k ohms the other side to earth (which makes no sense at all). It was showing no connection to earth before installation and after testing when it failed after new heater installed (though in hindsight that was with no water in the drum). I have now disconnected the element connectors and am continuing the wash cycle to see what happens with it disconnected. Once the load finishes I will pull it apart and get the new heater out so see if there is any physical damage.
