Product review (2 stars): Auto Load sensing - good idea, bad implementation
I bought Whirlpool WTW57ESVW1 from Sears more than a year ago. I still hate the Auto Load sensing implementation. It wastes water more than the benefit of "not worry about the water setting". This is why:
1) if you forget a piece of clothing, it must wait for next load. Otherwise, if you lift the lid and put it in, the machine will fill up the tub with water, no matter how full the load is, or how small the piece of clothiong is. this is a waste of water.
2) After prewash or soak cycle, if you turn the knob to wash, machine will fill up the tub with water, no matter how full the load is. this is a waste of water. Unless you turn the knob to drain first before starting wash cycle. This way also wastes water because you cannot re-use the soaking water and detergent

Auto Load sensing is a good idea, but Whirpool has a bad implementation, not mention other tech/liability issues come with the sensor. Whirlpool should have had a Auto-Load-sensing bypass button.
