<rfi@contesting.com> Subject: Re: [RFI] LG washer WT1501CW - EMI If I had to
make a somewhat cynical comment, I'll bet the contractmanufacturer eliminated
the "simple line filter" to cut costs. After all,the line filter adds cost and
does not contribute to the performance of themachine. Remember, home
appliances are exempted from radiated andconducted emissions by the FCC.Dave -
