the machine i have, on the normal setting, does not fill with water on the rinse portion of the cycle.  service has been efficient and boards have been changed.  but the problem exists rendering the normal setting useless.  
tech support has not identified any error codes.  therefore i believe this machine has a design flaw.  i was told "just don't use that setting".  however that setting is appropriate for most loads of wash.  and i paid for a machine with 6 wash settings not 5.
this is an excellent machine i am pleased in every way accept for not being able to use the preferred setting.  if i could use normal the rating would be 5 star!
at this point i would not recommend a samsung washer to anyone!
