Product review (1 stars): doesn't work, but I found a work-around
I so wish I had read these reviews before buying this washer! It DOES NOT add enough water to get all the clothes wet (I confirmed this by opening during the cycle)! So it is physically impossible to clean them! And yes, the spots are residual detergent that didn't get rinsed off, for the same reason. The good news is that I found a solution, rather than mess with exchanging it. If I WET the clothes before putting them in, the extra (water) weight fools the idiot machine into adding enough water. This also means I have to add the detergent (already diluted) after starting the machine, because it will first spin to remove excess water, before adding water. Perhaps this doesn't "save" as much water as intended, but at least it works this way. Otherwise, saving water is pretty worthless, if it doesn't work!!!!!
