Bad News ----  Appliances are exempt from the stringent rules.


The folks who made our washing machine were fully aware of this when I
contacted them.

I would, at the very least, file a report with the FCC.  This device is 
most likely not compliant with the conducted emissions requirements.  
Fixing these devices one at a time is getting really old.  In my 
neighborhood alone I have dealt with 5 grow lights, 3 halogen lights, 
and one surveillance camera.  All have been Chinese imports.
