Bowtie Impeller
Mike: I've been looking through my G.E. Parts Catalog listings. There is a small margin of error here because I'm looking at the dates of the Parts sheets, which may have dates that don't exactly coincide with manufacturing dates. Looks like the last Black Impeller dishwasher was the SU60N - the parts sheet is dated April 1957. The next model in sequence in the Part sheets, is the SU60P and SU60P1, which had the Bowtie Impeller - the parts sheet is dated January 1958. The above are stationary dishwasher units. The Portables (excluding the early Round models) of the Mobile Maid era begin in the parts sheets with Model SP40M1 - which used the Black Impeller - the parts sheet is dated April 1957. The model SP40N and SP45N are variations with the same April 1957 dates. The Mobile Maid that I believe you are referring to, Model SP40P, is the first portable to have the Bowtie Impeller - parts sheet is dated January 1958. Various models follow - with dates as late as December 1962 - all of which have the Bowtie Impeller. Then there are new models introduced with the Spray Arm - with dates beginning in July 1962. And the impeller, as we know it, was gone forever. Summary - Bowtie began in 1958 and lasted through 1962. Mike

i picked up a g.e. repair master recently from my friend in buffalo and it also said that they began using the motor and pump that goes with the bowtie impeller in 1957 so it sounds like 1958 was the big year for the bowtie! | ||

Neat!
I am wondering if that GE I just scored in Kentucky may be one of the first spray arm models... Further question about the GE impeller washing system: on some models there is a stainless steel bracket or channel on the bottom of the tub at the rear - what did this do? Was to help draining or did it help redirect the water spray?? The machine in the picture is a '59 pull-out model.

Mike, if you look in the photo above you can just make out the bracket - it is almost in line with the cutlery basket but at the back of the tub. The story behind this poor "princess" is a sad one... I can tell you all about it when I am in Peoria for the wash party. This was my first foray into the world of vintage dishwashers and it didn't have a very happy ending! | ||

It's called a Water Vane
Paul, In the Parts Sheets, it's called a Water Vane. I've studied the one on my Mobile Maid, and I can't really pinpoint exactly what it's purpose is. Why just one? Why not 2 or 4 of them to balance the water distribution better, if that's what it's supposed to do? I give up. Anybody else have a theory? Mike

Anti-swirl
I think the vane also prevented the formulation of a swirl around the drain, since the rotating impeller would have influenced the "spin" of the water beneath it. This helped force water to flow down into the drain, instead of spinning endlessly around it. The old belt-drive Kenmore washers had a vane similar to this right next to the pump intake. | ||
