You could try this under base loads electrical. Let us know if it works.

Dryer Location: Select the location of the Laundry Equipment in the house from the choices available in the list. This input is coordinated with the dryer exhaust field in the ventilation screen. If this field is set to "No Laundry Equipment", the dryer exhaust field in the Ventilation screen is set to "N/A" and is not available for use.

Thanks for the replies on this.

Switching or modifying the machine location didn't have any effect.  We tried moving that in a few different ways.

 The conclusion is that the room function does not work in EG mode.  It needs to be run in general where we also got a number of pretty random looking errors.  Those errors were created by custom window codes.   So in order to use the room function we needed to produce a model with no custom codes and run it in general mode. 

We got the results we were after seems like a silly work around.
