Over all it's a great set any you will love the dryer more than the washer because it has 5 drying temps and very sensitve to the load using soft heating!
As for the washer, soak or prewash can be used with every cycle. And for the shortest wash cycle, use rinse and spin and add second rinse.
Press desired cycle speed then hit rinse and 2nd rinse = 16 minuets total 22 minuets in real time (Fill time).
You can do an overnite soak by filling the washer, agitate for a few minuets, stop/cancel the machine, hit delay start for 9 hours with all cycle modified to your likings and off to the races!
Enjoy your beautiful set.
