This machine does seem to be heavier than a Maytag TL which is comparable to this. This machine weighs 159 lbs, the Maytag MVWC416FW comes in at around 144 lbs, a 15 pound difference. Both machines are the same capacity, come with deep fill options and contain some form of agitator.
That spray rinse was interesting. I like how it pulled the water through the clothes then added more water. The spray rinse also seemed familiar...WP resource saver anyone? Those did 6 spray rinses during the spin, this machine, with the limitation of modern restrictions, did 3. Go figure.
Another thing which got me, again the spray rinse. The video had extra rinse off which is why some could argue to why it did not fill up to the top. However the manual *SEEMS* to state otherwise. Nowhere in the manual does it say to select extra rinse if fabric softener is added. In fact, it also clearly states you can add fabric softener manually during the final rinse if preferred. Once again, no mention of turning on extra rinse.
Based off of that, I can only draw one thing. The machine is now smart enough to know how light the load is and realizes that for a load that size, a spray rinse will be enough, but it will also be enough to satisfy testing needs. That's almost a nudge from WP to do heavier, larger loads (to provide better rinsing) in this *commercial* machine to resonate the meaning of commercial...smart.
