Hi Dan,
You may purchase dishwasher installation kits from retailers such as Best Buy, as these include the recommended power cord. To find out which dishwasher installation kits are available, please contact Best Buy’s customer service at (888) 237-8289. They are available 24 hours a day.
They can answer your questions directly or transfer you to your local store for assistance with your specific concern.
Please note that Samsung’s dishwasher installation kit is not sold separately. It is only available when purchased with Delivery + Installation through the Samsung website for this specific dishwasher model.
