MJD2000AAW is an Australian model.
The control panel is bad, you get stopping mid cycle, no heat won't empty, code E3... etc etc. You can get OEM replacement or get yours fixed:

No affiliation with them at all. Cost ~ $111, which is approximately 1/2 cost of OEM module.
Be careful as sometimes the controller fail trips the water heater cct breaker as well.
This issue effects MJD2000AAW and MJD3000AAW.
