WOW.
They don't even sell the multi-orbital spray arm anymore.
PartSelect nor Repair Clinic have it listed anymore.
Their solution is to replace it with a straight spray arm.
Here's the drawing though...
When I was a young kid I would pester GEAnswerCenter.com with emails every week.
They told me the following about the wash system:
"SmartWash System"
8 powerful jets yet with a gentle fan spray.
The multi-orbital wash arm has 5 jets. 4 for dishes and one for the filter screen and driving the arm. The smaller spray arms rotate at 75 RPM with their jets fanning out at a 25deg. spray. The main arm spins with the small arms on each end at 30 RPM.
The PowerTower sprays dishes with two 25deg. jets also, as well as the PowerShower sprayer on the top of the tub.
Water passes through the sump screen and then the "soft food disposer" to the pump. The pump moves water through the system at 30 gallons per minute. Water falling through the machine randomly falls through the course screen in the top of the rear micro mesh filter and any food particles with it are strained out.
The lower arm jet sprays at this filter to keep it clean and push food soil into the bottom collection chamber. During drain, the chamber seals, flushing soil out with the rest of the water.
