[RFI] LG washer WT1501CW - EMI

[David Eckhardt]

If I had to make a somewhat cynical comment, I'll bet the contract
manufacturer eliminated the "simple line filter" to cut costs.  After all,
the line filter adds cost and does not contribute to the performance of the
machine.  Remember, home appliances are exempted from radiated and
conducted emissions by the FCC.
