earthling, you're completely right! I've wondered that for a long time. Lots of newer top loaders have totally foregone the out of balance trip switches. GE, WP, Samsung, Frige, Elux etc.
Only in the last few years of high tech washers have the out of balance trip systems come back, and only on a few brands.
It really is a critical failsafe, especially with these high spin speeds we're at again, and with mostly plastic washers. (Even though there are some amazing plastics out there, honestly).
Whirlpool's FL and TL machines ARE using sophisticated G sensors on their tubs to control out of balance situations. My Maxima must've had some items shift in high spin one day, causing it to loudly vibrate. The machine caught it and immediately killed the cycle. It was far along in the cycle so it just ended. But if not, it likely would've rebalanced and tried again.
WP's TL machines can sense vibrations even if your feet aren't level or if your floor isn't stable, and it will throttle the high spin to those conditions.
Shameful Samsung, and many others, are cheapening out and totally relying on the limited ability of their balance rings.
Being in engineering, there are only two options I foresee.
The engineers did have a system, and it got overruled.
OR, they contract outsourced some of the design, and the less experienced engineering contractors did not consider an emergency system, likely because the client [Samsung] said don't bother.
As for why companies abandoned the pedestal suspension, because it's actually less forgiving with vibrations, and higher spin speeds would not meet the smooth, quiet operation that customers demand. More stable? Maybe, but if there's anything that the balance rings can't handle, all those vibrations would immediately get sent to the floor.
If you get into a harmonic frequency situation, especially at these new high speeds, you can start to do REAL damage to peoples' wooden 2nd floors. Where laundry is increasingly put.
Old days had the washers in the basement or garage, on concrete slabs. There's no concrete on 90% of peoples' 2nd floors.
Hanging suspensions totally isolate vibrations and frequencies from the cabinets and floors.
