Mark, I did a teardown of one recently and was able to use a US repair manual for diagnosis.
The main changes in the AU spec, are cold fill only, the bleach dispensing section in the drawer has a lid on it and the heater is used in every cycle. The dispenser mechanism has a position for bleach and also a position for hot water inlet, but the computer seemingly just ignores those. The computer is labeled for AU and Europe.
The cycle lengths are european, it generally runs for around 1.5 to 3 hours depending on the cycle.
Unlike the Neptune's that only had a 1.3kw element, these seem to heat with a full 2kw.
