We purchased an LG diswasher model LDE6920ST 2 months ago.  It hasn't gotten the dishes clean yet.  The serviceman has replaced the sump and the board and it still doesn't work.  LG is stuck into this routine of sending service people out over and over rather than replacing the defective dishwasher.  Everytime the service guy comes, he has to order parts that take forever to get here.  I'm washing dishes by hand for the first time since 1977.  I wouldn't recommend anyone buy an LG.  Their service department isn't reliable.
