I have one of the original Oasis machines from 2008 with agitator in great running condition. It has an automatic water level that can be overridden to 4 other levels. The highest, fills nearly to the top of the basket save an inch or two.
I Believe the default time on the Delicate cycle is 35 minutes, followed by 42 for Normal or Casuals. I love the machine and it cleans good. Great at removing stains.
My only complaint and this was mentioned in consumer reports is that the way the basket holes were stamped is that items could get caught on the holes and string. All of my towels washed in this machine over time would get strings all over them. I don't have the same problem in traditional WP/KM direct drives, belt drives or Maytag Dependable Care machines.
