The newer washers won't do much of anything if the lid switch is bad. The old top loaders are pretty simple. Since it will fill and empty, your regulator is probably okay. Can you hear the motor running? The motor connects to the gearbox with a plastic coupler. The pump connects on the other end of the motor. I'm going to bet that the coupler has broken. Marbeck appliance has them locally. Wear gloves as there are some really sharp metal edges in there. The entire cabinet comes off rather easily.
I'm pretty sure Appliance Parts Pros has a video on it. I ordered a few extras because those machines are everywhere: Kenmore, Whirlpool, Matag, etc.
