Standard American 220v Plug
Just peeped the plug on my German built Pfaff ironer, and can say they are the same.
When purchased my ironer, the seller stated his mother brought it over from Europe and used it until rather recently. From what one can tell the only thing done to the unit was swapping out the Euro 220v plug for an American one, and the thing ran, and still runs. Pulls darn near 3kW when the steam boiler is engaged.
Am not so surprised to see this older AEG unit at your local thrift. Many housewives who moved house to these shores from Europe brought their appliances with them.
If a company paid for the move, persons stuffed what they could fit into the containers. Coming on their own remember crossing the Atlantic via ocean liner was still a regular means of transport until the 1970's or so. Going by ship avoids those pesky weight restrictions (and costs) that come with air travel.
From what the German repairman who worked on my Pfaff told me, early European electric appliances were a bit more forgiving of frequency changes. Therefore the switch from 50hz to 60hz may not have caused much harm, depending upon the motor of course.
Today of course appliances have motherboards,computers and such that really must be on the proper frequency to operate properly. Miele has all sorts of transformers and the like built into many of the appliances it sells in the USA. This allows them to get around having to make special machines just for the "wacky" 120v or 220v 60hz system used here.
Buttons:
65C is about 150F, and 50C is 122F. So the last button either is for decreasing the wash temp (perhaps to protect fine china and crystal), or maybe some sort of "energy saving" scheme.
First botton is the universal "on" sign, the next seems to be "rinse" as in our "rinse and hold". Not sure about the "S". The "pot" button is for "pots and pans" cycle.
This model is at least 20 years old, and AEG has now recycled the number "525 i" for their new line of compact dishwashers.
Another thing, AEG laundry and dishwasher appliances have long been distributed in Canada. So this unit may very well have not crossed an ocean, but merely took a ride down south.
Several years ago there was an appliance dealer in Canada selling AEG appliances to USA residents. IIRC a few persons over on THS purchased washing machines.
However with no local sales, repair and installation network, don't think the scheme lasted. Persons whom reported problems said the vendor was quick to send required parts via post, and offer technical assistance via telephnone or computer; but when one paid that kind of money you kind of want something better.
Personally I'd look at the electrical service plate. If it runs on 220v 50hz (or better both 60hz and 50hz), and one has a 220v circut at home, it may prove to be a fun dishwasher to have around. Bet it does a fast and mean hot wash!
If the unit did come from Canada, there are enough current and or former AEG dealers who may be able to supply information/parts.
