A typical overflow protection float uses buoyancy to open a switch which cuts the power to the water valve vs sensing pressure based on the amount of water in the tub. My guess this sensor is variable judging by what (and I could be wrong) are 3 wires which provide variable feedback to the electronic control.
Tall tubs have limitation in general, these builder grade machines take it to a whole new level.
Personally I'd like to see the Power Cleans brought back at least as builder grade models. Prior to their discontinuation Power Cleans were already extremely economized. Whirlpool did away with the metal carriage underneath the tub, used the minimum amount of metal to hold up the machine and had the plastic thickness just right. The molded tubs would cost next to nothing to make considering the complex tall tubs being molded today. Timer and heat dry on/off rocker with standard racks and you would have the best cleaning in the world for the lowest price. No pre-rinsing of any kind, no filter to gunk up, no smells, no streaks, no long cycles, no break downs, no nonsense. People living in rental housing, in new homes and on a budget can actually save money and the environment instead of being forced to use more resources which ultimately costs them more in the long run.
crossed !
