This dishwasher (DMR78AHS) is terrible. We have called Samsung on many occasions and even had our call escalated to the executive level to be told nothing can be done. We get very poor performance with the washing cycle and now an error code (SE) does let the machine start up any more. Samsung have NOT been helpful and do not want to assist. BUYER BEWARE of this machine...you will be purchasing stainless steel for the recycle pile after a short time! Definitely not a recommended purchase!!!!!
