Not a field retrofit
This machine was built as a suds model. The "suds" setting at the bottom of the cycle graphics just left of the Delicate cycle is pure factory for suds models. Non-suds machines had a solid "OFF" section there. Also, the model number is another give-away, as 110.83392100 is a suds machine, whereas 110.82392100 is the non-suds variant.
The service panel on the rear with the cut-out for the suds valve is another clue. This machine was born a suds model, but I don't know about the use of that loop hose going from the suds valve. We don't have a lot of suds model washers in the South due mostly to the lack of basements and lack of laundry sinks, thus we don't come across suds machines very often to work on.
