Filter Flo in a solid tub
The washer fills until the tub over flows. When enough water weight has accumulated in the outer tub to trip a round sensor under a rubber cover the washer begins to agitate and water cirulates from the bottom of the outer tub, causing the wash tub to overflow, etc, etc. This washer has a one spped motor and a two speed transmission by means of a clutch. The washer agitates on low speed for 30 seconds or so and then shifts into fast agitation. It's indexing tub slows roll over and there is no spray rinse between the wash and rinse cycle, a drawback. I used to pour water into the wash tub while it was spinning to rinse the soap out of the pump and hose to keep from ending up in the rinse. It was a real work horse, new in 1959 and washed until 1979. It left our family of 5 in 1970 and went to an aunt with no children, so it had a much easier life after that.
