[RFI] Washer RFI/EMI

Looks like this series of Corcom filter may be worth trying on a washer with 
a VFD motor.


I just ordered one for my GE Harmony Profile-series washer.  It's now out of 
warranty, so I can try some more invasive measures.   To date, nothing has 
made a dent in reducing RFI/EMI from its direct-drive motor circuitry.  I've 
got a feeling that a total cure will involve attacking the noise at multiple 
points along the VFD circuit.
