There are two seperate motors.One revolves the wash drum at different speeds reversing itself during the tumble modes in duration to the program selected.For example,you load the clothes loosely to the top of the drum,close the door(not slamming it)ad detergent,bleach and fabric softener into the dispenser tray.(It dispenses everything at the correct time in each cycle.There is even a dam to hold liquid detergent for the main wash while dispensing detergent directly in during a pre wash),turn the program selector to the one that is best for the load you're washing.It will automatically set the wash and rinse temperatures,the wash time,dispenser differentials,the tumble times (normal is 12 seconds clockwise,3 seconds soak,12 seconds counter clockwise. delicate is 7 seconds clock wise,8 seconds soak,7 seconds counter clockwise.The hand wash is 2 seconds clockwise,13 seconds soak,then 2 seconds counterclockwise.)the drum spins counter clockwise for each spin speed (600 rpm,800 rpm,1000 rpm and 1200 rpm)these spin speeds too are set automaticly on the seperate cycles.They are however adjustable higher or lower than the preset speed for any cycle but it is fool proof.it is impossible to set 1200 rpm spin for permanent press,delicate or wool fabrics and if you select the sanitary setting you can not change the wash and rinse temperatures.
It has 3 seperate,evenly distributed wash/tumble arms that help keep the clothes from tangling as well as work like a scrub board.This is not only gentler than any agitator but also gets clothes thoroughly washed and rinsed.Instead of using 55 gallons of water for a wash and a rinse,it uses about 20 gallons for a wash and 3 rinses!!!it also uses 1/3 less detergent,bleach and fabric softener.at 1200 rpms(twice the speed of most top loaders)this machine removes so much more water that once the load is in the dryer and a second load is in the washer,the dryer is finished before the next load in the washer.Mine is usually on the final 3 minutes of the final rinse.During the spins it also balances itself so there is less wear and tare on the mechanism.
During the beginning of the wash cycle,if you need to open and ad or remove anything,you can because the use of less water means it's never going to be high enough to not be able to open the door.there is one rinse that fills above the opening but the electronic door lock as well as the program setting will not allow you to open the door at that time.each cycle has 3 different time settings depending on the soil level of the load.
The matching dryer is great too.It has a huge drum that lights up when you open the door and several auto dry settings with 6 different temperatures.It also comes with a no-tumble drying rack for sweaters,tennis shoes,stuffed toys and lengeret.It also has a reverseabel door,see through window,white enamal interior and 3 way venting.
I highly recomend them and am very satisfied with mine that are now 3 years old with no problems whatsoever.
