[TenTec] High speed washer hum/whine

[Phil Sussman]

My first thought, having a similar experience with a sewing machine, is
to determine the input source. In my case it was NOT the power line,
but rather DPI (Direct Pickup Interference) on an IF frequency. The
answer I found was to filter the source and I added CAPS to the 
sewing machine to eliminate the problem.

I'd look for the source at the washer and try to eliminate it there.

Good luck,
