after 2 weeks it stopped cleaning the dishes even with excellent cleaner, booster and using the storm wash.
called customer service and they arranged for a service company to fix it. arrived after about a week. diagnosed the problem, microswitch. 
worked great until 3 weeks ago. same problem again. 
samsung would not replace it until it has been repaired twice. 
so we won't have had a working dishwasher for about a month over the holidays. 
tried to get samsung to get it fixed quicker. called again on 23rd dec. someone from a higher department will call you within 24hrs to get it resolved. still waiting. 
will never buy a samsung product ever again. shockingly poor customer service. they just don't care about their customers.
