 Hello,
I finally got LG's attention via their FaceBook page...
This following is LG's PM response to my emi complaint:
"David, please see below response received from our engineers. 
This would fall under FCC(Federal Communications Commission) 
Rule Part 15 specifically. Basically this states that the radio must 
accept any interference from a device that emits an unintentional 
frequency that can interfere with other electronic device's operation."
Time to contact the ARRL.  Who's the go to person at ARRL?
Thanks & 73's

 Hello,
Has anyone gotten factory EMI support for LG's WT1501CW washer??I am curious if any others have gotten factory support for this problem.
I have started a conversation with LG support line, we will seeif this goes anywhere. Their customer information line didn't havea clue, has anyone else complained?

This machine impressively wipes out 80 and 40 meters with it's 
variable motor control electronics.  I don't want to look at 160 meters.  
The factory service manual shows an simple internal line filter but at 
my QTH it's not doing much good.https://drive.google.com/file/d/0B-i5KqMA2RZwcHktSWk1SW5tNEU/view
I have inserted a short AC jumper line-cord (with line filter andcommon mode FB) between the washer and the 120 outlet and 
this greatly greatly reduces 80 and 40 meters interference... 
I'm using a Schaffner FN-660-20/10 line filter an Fair-rite 264380302 
FB on the cord end, about 7 turns around the core.I can send a picture if this would help anyone else.
