Actually Stan, I haven't managed to do that yet--overload the Visimatic. The booklet says if the motor gets too strained from an overloaded tub--or from a wringer left jammed for too long, I suppose-- the button will pop, shutting down the whole shebang, kind of like the reset button on the Frigidaires.
Please don't tempt me, but boy, do I want to see that button pop so I can enjoy the fun of pressing it back in.
