If your Samsung dishwasher isn't sealing as it should, the O-ring (DD81-01544A) might be the issue. This genuine Samsung part fits in the top control dishwasher with a stainless steel tub, helping maintain the integrity of your appliance. Before replacing this O-ring, unplug your dishwasher and shut off the water supply. It's advisable to wear work gloves to avoid injury during installation.

Check your appliance's model number for compatibility before purchasing.
