Yeah, unfortunately, that method of RFI prevention doesn't work when
your neighbor buys the same piece of junk!
Yes, I specifically avoided Whirlpool and Kenmore due to the RFI
reports. I went with LG figuring it would be better to buy a
washer/dryer from an experienced CONSUMER ELECTRONICS company rather
than an old fashioned washer/dryer company. I guess I won my bet.
Fortunately (or unfortunately) for me, most of my RFI comes from a bad
PG&E power pole 2 doors down and from Ethernet. Ethernet affects
14.030MHz and several other discreet frequencies up the band. I can
avoid that 1Khz of affected spectrum most of the time. The PG&E power
pole is another story. PG&E has been trying (if you call what they do
trying) to fix it for 1.5 years. A 12ga. shotgun blast would probably
fix it quickly, but I'm not likely to get away with that :-)
