It's not impossible that the motor controller uses some digital

My washer runs the drum forward, backward, and a variety of speeds. That
could be done via direction and speed, but also could be done with
digital commands.

RS-485 is quite common as well..though I dont see much need
here..unless it has a digital control unit.
