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.
