Hello,
Most older washers and dryers use a motorized timer to sequence events. At
the end of the cycle, this motor must drive a set of contacts that
disconnects the timer motor. The designing engineers hope that there is
enough inertia in the gear train to separate the contacts before the
mechanism stops. Unfortunately, this is not always the case. The result
is a small spark-gap transmitter spreading RFI. Newer, CPU-based
appliances should not have this particular problem, but might have others...

I think the question was "what in a washing machine could cause RFI"?
If it's energized by volts it can spark!
