Replace your dishwasher's faulty door hinge with the genuine Samsung DD97-00251A hinge-left. Positioned at the bottom of your dishwasher door, this part pivots to facilitate smooth door operation. If your door is not opening correctly, or there are issues with its alignment, it might be due to a worn-out hinge. For safety, disconnect your dishwasher from power before installation, and use work gloves to protect your hands. Check your dishwasher's model number to confirm compatibility before purchase.
