G.E' POTSCRUBBER 1200 unique spray arm

[rollermatic]

not sure if this is in the right forem or not. thought it was made before 1985 but i may be wrong here. if so i'm sure robert will move it for me as he has done before.

it was given to me a guy i bought a kd-21 off of. i was gonna pitch it cause it has a plastic tub and i'm not into dishwashers made of plastic usually. but when i got it home and looked at it i saw that really unusual spray arm and decided to keep it.

i remember someone here had mentioned this spray arm last year on a post so here are some pics.

here's that

spray arm. never seen one like it before.

also very curious about that small mesh screen filter device in the back. i know the drain line hooks up to it but i have not had time to tear into it to see how it works.

the replacement

spray arm for this machine you can get on the web is not like this. it's a simple 2 arm spray arm like everyone else has.

motor and pump

unit.

for a small pump

and motor it really moves the water!

doesn't leak a drop and runs very quiet.

the drain hose connects

to this port which is part of that screen/filtering device on the back inside of the tub.

one of these days i'll take it apart and see how it works. i know g.e. has used this quite a bit. drain line also has a check valve on it past this port.

another view

of this device.

all in all a very quiet machine that washes great! has a long main wash period and 3 after rinses that i always liked on g.e.'s.

we got our first "new" dishwasher in 72 when i bought my aunt a g.e. portable front loader. wanted a kitchenaid but could not afford it. hated the g.e. as it was everything a kitchenaid was not! plastic coated tub, horizontal pump and motor, spray arm only had holes on one side, feet popped out of the lower front panel when you opened the door. i thought it was a complete joke. but it did a great job and she had it forever! i slowly began to love g.e. dishwashers. this one reminds me a bit of that first one!

That wash arm is called "Smart Wash". The idea was that it would be like having 2 MultiOrbit wash arms at the base. It changes the water patterns so it not always the same ol over and over again. That wash system does well. The filter in the back allows the water to fall into the top course filter and the water runs to the middle where its filtered thru the fine mesh. The food thats caught on the backside is washed off by the jet at the end of the arm and falls into that tank under the dishwasher. When the dishwasher goes into drain there is a check valve that closes the opening in the filter chamber. Thus all soil trapped is whisked away down the drain. Simple yet very effective design. The dishwasher moves about 35 gpm. Not bad compared to lets say a Frigidaire dishwasher of today that pees a measly 12 gpm.
I had a Kenmore version GE built dishwasher with the MultiOrbit Arm and that nice deep Super Upper Rack. That rack system could hold a ton of dishes. Oh and that machine is from the early 90's I wanna say maybe 92-93.

very interesting

S.M.E.G. diswhashers have a similar double sprayarm, called "orbital system"

... and translating system

for slimline dishwashers

GE dual orbital wash arms

The dual orbital arm replaced the 1980s multi orbit arm it seemed like a really good idea but in my experience I don't think it worked as well as the 1980s design. I got a lot more complaints from my customers with the newer design, and GE didn't keep it very long.
