I pretty much like my hands the way they are--so while I'd once relished in the thrill of washing my tub spin, (via "something" that I'd inserted in my lid switch, that I simply don't recall) I wisely kept my distance away, and even think back to the few times I shift things around in the tub while the agitator is just moving, with it never occurring that my hand could get caught in the action & too late to free it if it ever got snagged in the garments of clothes that I need to turn off the machine first (and usually move to where the water fills & allow thew additional water being added to mat down the material so it gets its dunking & drubbing, rather than force it down)...
A delay in a dryer switch being available for our dryer led the repairman for it to temporary bypass the switch needed to shut it off when the door was opened, and only once or twice had I opened it during that pending repair, after convincing the repairman we would leave the door shut until the dryer completely finished its drying; it was maybe the FIRST time that I'd FORGOT, the SECOND?--er, well,...
