That washer in the POD is VERY similar to the one I grew up with.
Ours had the same controls except had no water level selector - just a timer and 5 temperature buttons. Ours was the Deluxe. (Not rapidry.) It was the Multi-Matic mechanism underneath, but had the Jet Action agitator shown in the photo.
I'm not certain but I don't think Rollermatics were ever sold in Australia.
I'd love to know how old that advertisement is - that would tell me about what year our family machine was made.
Semi-automatics:
No timer, just a function selector - Wash/Off/Spin. (actually: Pulsate/Off/Spin Dry.)
Fill tub manually with a hose. Turn off taps when full.
Set selector to Wash.
If the model has a clockwork timer, set timer for Desired wash time. (Max 15 min.)
If model doesn't have a timer, it will start to wash when selector is set to Wash.
When Wash time is up, set selector to Spin to drain and spin. (again, set the timer if it has one.)
Repeat the process to rinse.
My round body Pulsa Matic has no timer, just the Wash/Off/Spin selector.
