Whirlpool washers had a dry agitate test increment. I've never tried it while the washer was full of clothes. But it has gotten me thinking- what happens if you were to set a top load washer to agitate without water, while full of dry clothes? What would happen to the machine? I'm thinking of something like a Whirlpool direct drive with a dual action or straight vane, Maytag Dependable Care, ect. Has anyone tried it?
