We recently acquired a front loading Exectrolux washer and dryer pair.  The 
dryer puts out strong RFI all the time.  The only way to quiet it is to 
disconnect it from the power circuit.  The noise sounds like steady power line 
noise and radiates strongly from the power wiring throughout the house.  The 
noise extends into the VHF range.  

I contacted Electrolux.  Their response was that they had never heard of that 
problem.  They only suggested I try grounding the cabinet.  That is not 
practical.  The laundry room is in an inner room of the basement and has PVC 
pipes.  Any ground connection I could produce would be so long that it would be 
ineffective for RFI.  

The washer puts out a different kind of RFI.  It seems to come from the control 
circuits and motor drives.  Unlike the noise from the dryer, this RFI is only 
present when the machine is in use.  Also, its amplitude is much lower.
