Normal with WP DUET
I own the WFW72HEDW which is the BOL version, and Yes I do not see any sloshing on the Normal cycle either, or water when it's empty like that. Nonetheless clothes have been coming out clean since the the day we bought it (2 years ago).
On the Normal cycle, the machine will completely saturate the laundry, despite there not being any noticeable sloshing, what creates the cleaning action in any FL'er is the rubbing together of clothes like the old days would mimic rubbing clothes on a wash board.
On my machine I use the normal cycle a good 80% of the time and with larger loads, I can see water droplets falling from the clothes as the tub tumbles the load.
Water usage on my washer:
Normal: Least water usage
Eco Sanitize with Oxi: Most water usage
Heavy Duty: 3rd most water usage
Drain and Spin: NA
Quick wash: 2nd most water usage
Delicates: Third Lowest water usage
Cold wash: Second lowest water usage
A couple of things I do with my WP Duet is...
-DO NOT wash small loads on normal, instead use the quick wash cycle and select soil to your preference, on the highest soil selection on the quick wash cycle, you will get a FULL 10 MINUTES of wash action.
-If the tub is anymore than 3/4 full, DO NOT use normal, and instead use Heavy Duty and select the light soil. Generally, if the clothes line up to just under the water spout on the boot, your good, any higher and the unit is either being overloaded or you may need to pick heavy duty instead.
-Spin speed wise, if the tub is half full or more, then pick medium or high, with some exceptions of mixed loads being placed at a lower speed other than high. Anything below half full, should either be slow or medium, with exceptions of an equal number of towels, etc.
