Re: "Exploding"?
"I recall that one washing machine I owned did exactly that: it would stop the spinning, rotate back and forth a few times, then try anew."
My current samsung (front loader!) eco bubble does that if it finds the load is unbalanced, swishes round a couple of times to try and level it before going hammer and tongs on the spin cycle. A couple of times with a big heavy sheet it's refused to spin.
