GE filter flo washers were somewhat popular and well known by this time. This model was a couple of years before the introduction of the V12 filter flo machine. This machine had a solid tub, but a positive fill regardless of water pressure. Like more than one solid tub washer, the fill had to overflow into the outer tub and a pressure switch at the bottom of that tub would activate it to start the wash and rinse cycle. There was also a water saver switch to activate it for a partial load. These machines were pretty good at washing, rinsing and spinning out the water.
