The power cord on the Fagor is not the removable type. However, the washer did come bundled with an adapter. There was the round twist-lock type plug on one end which ran into a plastic electrical box with two NEMA 6-15 outlets on it. This is probably what you're looking for. In my case, it came with the washer.

EDIT: Maybe the plug on the adapter wasn't twist-lock, but the pins were in a circular formation. To me, it looked like what's commonly used for electric dryers in the US.
