Peter, welcome to our club!
I have the FAV9800 (the one w/ the touch screen) if you want to ask any questions about it. I don’t know how the mechanism makes those snails spin around. It does seem to be designed like the old Maytag washers (the motor turns one way to agitate and then reverses to spin). The snails (tumblers) both turn in one direction.
On Sturdy the tumblers spin at 56 R.P.M. the entire wash time.
On Cotton at 56 R.P.M. for 45 seconds and pause for 15 seconds every minute.
On all other cycle they spin at 40 R.P.M. for:
Wrinkle Control 30 seconds w/ a 30 pause each minute.
Delicate 15 seconds w/ a 45 second pause each minute.
Hand Wash, I can’t remember if it’s 5/55 or 10/50.
In the rinse they always spin at 40 R.P.M. w/ the respective times above depending on the fabric selected.
It seems to work best w/ large loads. It does tangle a little (more w/ long sleeves and long pants), but as long as you use the correct fabric selection the clothes untangle easily. I shake everything a little as I put it in the dryer and the wrinkles do come out.
It's the best machine I have ever used to wash a blanket, bed spread, or comforter (ever better than a front loader except for the spin).
