Purchased the washer/dryer set today to replace a Kenmore set.  After setting up began the calibration as per the manual and the washer only buzzed, and lasted for about 5 min then shut off.  Tried to run a cycle with no laundry, same thing.  The door was even able to be opened as this was happening.  I am familiar with the sequence of events when a cycle starts as the Kenmore is identical to the Samsung and there is no door lock after any cycle is selected.  It just goes bzzzzzzzzzz......  So needless to say this is an absolutely horrible experience and not one that I predict is able to be resolved promptly after dropping 2.5k on the set.  I'll be in touch with Best Buy tomorrow to begin this process.
