For a '70s Washer:
There's always the mighty Maytag 806. There are two basic generations of this washer in the '70s - an early one with a blue control panel, a "real" bleach dispenser with the fill on the right of the tub opening, a tub light and a chrome-topped lint filter.
Later in the decade, Maytag changed the control panel accent to gold, replaced the bleach dispenser with a simplified unit with the fill at the left of the tub opening, and killed the tub light and chrome-topped lint filter.
Both generations are workhorse machines. If you really wanna knock yourself out, the Holy Grail of Maytags in this era would be the 906 machines, so automated you pushed only one button to start a sequence of events that could not be altered in the slightest. For that reason, the 906 was not as popular new as the 806; even Maytag touted the 806 as being for "The Woman Who Wants to Set Her Own Washing Procedures."
There are also '70s Lady Kenmores that are extremely nice machines, although they are more mechanically complex than Maytags. The "hot" machines are the "garage door" models, which have a faux woodgrain cover that slides down over the control panel when it's not in use.
