old European dishwashers in Australia
I do think it was these older 1970s Zoppas models I have heard of.
From 1979 my sister used to work for the Trading Post, a weekly newspaper of second hand items for sale. (Ebay on paper...) We used to get a copy of the Trading Post every week and of course I always read the washing machines, dishwashers for sale columns.....
Zoppas dishwashers were not common but they would be advertised from time to time. If they were sold second hand around 1980 then they would have been from the 1970s.Zoppas fridges were sold here too.
Melbourne had a very large Greek and Italian migrant population since the 1960s. The inner suburbs of Richmond, Collingwood, Carlton, Fitzroy, Brunswick, and Coburg all had big Italian communities and there were small importers who brought in Italian brands both of furniture and appliances. Bendix washing machines importer was in Brunswick, and there was a small business in Coburg who was mainly a washing machine and fridge repairer, but who also imported Zerowatt appliances in small numbers. (That business still exists at the same address, but is now just a repairer, not an importer.) The Zerowatt appliances I saw were late 1980s but I don't know how long he had been importing...These would only have been sold locally, the customers would have mainly been immigrants who preferred to buy the brands they knew and trusted from home, and to deal with a salesman who spoke Italian.
In the late 70s and early 80s the only front loader washing machines you would find in most electrical stores would be a Hoover or a Pacific (rebadged Gorenje.) Other brands such has Asea, Miele, Bosch, Bendix, GEC, and so on would have been in small specialty stores in the inner suburbs with large migrant populations. Dishwasher brands would have been similar.
