Late 60s TOL GE DWs
Hi Bob, there are only a few differences other than styling that I see, the earlier model has a wetting agent dispenser that has to be set for each cycle if you want WA dispensed. They both have the gentile-wash option for Christal-China that air-rates the water to reduce washing pressure.
Interestingly they both have the little wash-arm under the SW basket, but on the newer E model DW it was NEVER connected to water FROM the factory, GE found out that having this feature connected caused some type of performance problems and whenever we serviced one of these early DWs with this feature we were to install a rubber plug under the SS arm to stop all water flow through it.
By the time the E model was assembled GE stopped hooking up the SS arm in the factory, BUT continued installing the silly little wash arm till the sales literature could be up dated and the feature deleted, you have to wounder how many people wondered why the SS arm was always in the same position at the end of a DW cycle, LOL.
