Suds return answers,
<span style="font-family: comic sans ms,sans-serif; font-size: medium;">The suds return was an option on US washers that allowed a person to save the wash water from one load to the next. Water was pumped out into a tub or sink (providing you remembered to select that option, put the stopper in the drain, and your sink was big enough to hold 18 gallons, more or less). Then for the next load, you moved the dial/lever/switch to "Suds return", and the pump reversed, sucking the wash water back into the washer. During the rinse cycle, any heavy soil in the saved water would sink to the bottom, allowing it to be reused for the next load. For the 2nd, 3rd etc. loads, US detergent mfrs. suggested adding about 1/2 cup of detergent to each subsequent wash load. In GE machines, the returned water was indeed pumped back into the tub via the Filter-Flo system. </span>

<span style="font-family: comic sans ms,sans-serif; font-size: medium;">Maytag was the last US mfr. that produced a suds-saving washer. They stopped production in the mid-'90's I believe.</span>

<span style="font-family: comic sans ms,sans-serif; font-size: medium;">Feel free to correct any mistakes I might have made. A suds-saver is actually quite a "green" appliance. I wish they would make a comeback, but I don't see that happening anytime soon.
