The pump sounds completely different compared to my Whirlpool WFW72HEDW, but the rest, mine behaves exactly like the video including the giggle (LOL). The spray though is nice and looks very effective. Wish they did use it as a spray rinse during the final spin... | ||

This jiggle is typical for those direct drives. As far as I know, this is the motor calibrating into a certain position. | ||

The term for the motor movement is "cogging". This happens when poles of the motor align with one another when the phases of the motor are energized.
Once the motor is locked up then they pulse the phases to get the drum to turn. It seems as if they have to release the power from the phases when they do a reversal. | ||

 My original DD WP WFW97 does things differently. If it's not balanced properly, then it stops and tumbles back and forth and then tries a distribution spin. All that time the pump is going on and off and on and off. Once it's ok, then it will begin to ramp up spinning. Mine also tumbles back and forth during draining. For the final spin it ramps up to about medium for a minute and then stops and tumbles back and forth again for about two minutes and then begins attempting to balance again and then goes into final spin. Mine slows down to distribution spin speed and begins filling for rinses and does that for about a minute before it stops and goes into tumble mode. I didn't watch the entire wash cycle, fast forwarded to it to get to the rinses. I guess the recirculating spray didn't come on again during the wash. I was disappointed it didn't do recirculating spray during the last rinse, only the interim rinse. I also like that it continues to do a distribute spin and slow slightly to let some fabrics fall and redistribute. Mine just stops and begins tumbling back and forth all over again. This is an improvement. Probably cuts 20 minutes off my cycle times. But I wonder if the supplemental heater came on at all during wash. Initial time was 1:20, but cycle didn't last that long. That's what you get for not using fabric softener--plastered fabrics on the drum even with the fluff minute. | ||

I don't understand how direct drive motors have contributed to getting the spin distribution correct. How is this different than a belt drive model balancing a load and spinning without imbalance? | ||
