Jacques Cousteau, indeed, Uncle Bob!
Holy Crap, Andrew! This is un-frigging-believable! Today, Automatic Washer went underwater for the first time, and what a ride it was. Now that you've taken the plunge, we'll never be the same again. I've been down in the turbulence 3 times today, riding the wave, and I still can't believe it. You have the Special Effects Oscar sewn up, Andy.
In a lighter vein, did you know that there are washer-challenged people walking around who think agitators revolve rather than oscillate. I have spoken to such people. Obviously, they never wash at extra-lo. If they see this flick, they'll get it. Only the top goes round & round, not the bottom.
Neat how if you select Wash Only, Exact Medium level, Cottons, and Auto Temp, all chrome dials points perfect North when the load is done! Perfectionist Paradise.
Gordon, maybe the one digit difference is a fully marked water level selector--a wild guess!
AND......
What kind of agitator is in the 86 LK's you mention that don't have the Dual Action Agi?
