I hope that this will suffice, maytaga806! It is of a 90's "Whirlpool Gold" dishwasher with the PowerClean module. It is essentially what was rebranded as the Kenmore UltraWash. Other models will probably look similar. You may wish to send a message to "appnut," who owns a similar machine from around 2007 or so (replaced a GE dishwasher). 

I believe the lower wash-arm was called the 'Thunderbolt' wash arm. (Something tells me calling the series 'Thunderwash' wouldn't work well for marketing!)
