GE SP-40N!!!

Automatic Washer - The world's coolest Washing Machines, Dryers and Dishwashers

Help Support :

Is it my misapprehension, or did these models offer not even the pretense of a drying cycle? Not that it was necessary once the lid popped open. There's a mention of using it as a dish warmer, but I don't see anything on the dial.

 

I haven't used the dry cycle on my daily driver for years? Why bother? Those annoying little puddles in the bottoms of glasses and cups never go away with or without it.

Wonderful Brochure...

Interesting that it's so water efficient. It uses about the same amount of water as the new "Energy Star" models.
 
It's an "N" suffix, so I presume it's from 1956, since it appears that GE didn't run an "O" year.

For some unknown reason (to me, at least) GE model years skipped "O", "U" and "Z". ????

 

David, you're right, she does look a little like Sandra Gould or any of the unfortunate actresses who had to be the foils for the Three Stooges.

 

Hey Paul, were these Mobile Maids as noisy as the Front Loading built-ins of the early Fifties?

Most of the impeller dishwshers were pretty water thrifty, but without filters, it was the GE with the bowtie impeller and its Flushaway drain that excelled in disposing of food particles and to do that required numerous water changes. Our first one had 6, the next, 5.

In Ken's picture of the Hotpoint as well as in the picture of the GE's racks, notice the black Bakelite wash regulator in the center of the lower rack. That was really a great device which improved water distribution to the top rack. Remember those videos of top loading portable dishwashers where water delivery to the upper rack was uneven depending on where plates were placed in the lower rack? This ring with all of the little channels formed by the ridges or teeth around the inner part of the ring really helped even out the spray from the Bakelite impeller.
 
Ken,

I love the SP-40N Use & Care Manual. Thanks for posting it. I did not realize until now, how similar this reintroduced GE Portable Dishwasher was, to the other mid 1950's GE dishwashers such as the 1955 SE40M4 (sink combo model) and the 1SU60N (undercounter model). By 1955, GE had modified both the upper and lower racks for the dishwashers produced for these few years in the mid 1950's, as well as the silverware basket.

The 1953 model dishwashers were still being produced with the same basic rack design that had been used since before World War II. This design features the rectangular shaped removable glass tray in the upper rack. The only real change that was made in the design of that rack style, started to occur with some models, in 1950, with rubber coating.

Then in 1954 or 1955, the racks were radically changed. The lower rack was more rounded, with the plates tilted further back. The upper rack also took on a rounded shape, and that change removed any items from the immediate upper center section. The silverware basket was widened, and opened up from the former cup design. After watching several of my dishwashers operate, via Plexiglas lid, I have concluded that the Bakelite Impeller never did sufficiently lift water to the upper center rack area, even with the old style silverware basket removed. I do not know why GE waited so many years to figure this out on their own. They most assuredly had a huge customer dissatisfaction with the cleanliness of glasses in the center section of that upper rack.

In 1957, with the introduction of the next generation MobileMaid models such as the SP40S1 and comparable static models, the racks were changed again - back to a square shape. The upper rack in this design had a slight tilt built in, and the lower rack moved the area for large plates, to each of the four corners. Also, the silverware basket was moved to the upper front area. And we also have the introduction now of the metal bowtie shaped impeller. This, in my opinion, was GE's best improvement to dishwashing, which lasted until the introduction of the spray arm technology, I believe, in the early 1960's.

Experts:

Did the later  bowtie impeller simply spin around, like a blender blade, in a static puddle of water which then got thrown around (with pretty good force) or was it rotating in front of a stream of water that was forced up by the pump? From looking at it, it doesn't seem that there's a clear path for water to emerge at any velocity from that well.
 
were these Mobile Maids as noisy as the Front Loading built-

Ken, I don't have an SP-40N...yet... LOL  but the 58 and 62 MobileMaids are definitely not quiet machines.  Hubby, the comic that he is, loves to storm into the kitchen when one is running and shout 'Are you sure it's ON?'... 

The 56 pull-out in the Kitchen Centre is quite the noisy beast too.  I think the stainless counter actually amplies the sound! LOL

 

Funny about the drying cycle - I would have expected the MobileMaid would use the same principle as the pull-out's dry cycle - heated air moved around by the impeller. 

 

I think the wash action in the MobileMaid would have looked like this (from the 56 pull-out):

 

 
My parents first dishwasher was a GE Mobile Maid, from around 1961 or so. They used Electrasol detergent in it.
I don't remember much about the noise it made when running, but I do remember the special smell the insides had immediately after the cycle was completed. It was very unique.
