Jeff -
On the earlier 806 washers that I have used, the pre-wash fills, agitates, sits for a little soak, spins out, ending the cycle. On the soak, it will fill, agitate slightly to get the soap into the load, and will soak for about 10 to 15 minutes (not sure), then will continue into the wash cycle starting at the 10 minute mark - the best part for those nasty clean up rags that Greg has spoken of.
