I purchased what I thought was top of the line dishwasher by Samsung in March 2013,with in months of use it started "heavy" flashing light meaning a leakage, this has been an ongoing issue since purchase. The leak would start and cause dishwasher to shut down, and when the water dried it would reset itself, and the cycle continues almost every other month,after 3 visits by Samsungs so called repair techs they stated they thought the issue was fixed,but the dishwasher may have tub issues, so 4 months later the issues started again. So at MY expense the 4 tech arrives in July he states it is a tub leakage and is not repairable, my purchase warranty has now expired per Samsung, however it has a "lifetime" warranty on stainless steel tub leakage. How can I resolve this issue? Samsung will not respond to my request for replacement.
