Installing a new dishwasher can be a daunting task that many leave to a professional to handle. From unhooking and removing the old dishwasher to installing the new one, there’s at least a dozen or more steps to take with varying degrees of difficulty.

Because they usually don’t come preinstalled, one such step is installing a new dishwasher power cord. This article will show you the basic steps to installing one. (Pictured: GE Dishwasher Model #GDP665SYNFS)

Steps

How To Install A Dishwasher Power Cord

  1. NOTICE: Be sure to disconnect power to the dishwasher power outlet before beginning the installation process!

  2. Locate the power cord junction box underneath the dishwasher. It’s usually near the front.

  3. Remove the junction box cover.

  4. Insert the wire-end of the power cord through the round opening of the junction box. You may need to attach a clamp connector if the power cord doesn’t have a built-in strain relief.

  5. You should now have three sets of wires in your junction box. Match the wire colors (black, white, green) and tightly twist the exposed wire ends together.

  6. You may need to cut the exposed wire down to about 1/2″ from the insulation. Twist a wire nut on each end. The wire nut should completely cover the exposed wire.

  7. Tuck all of the wires neatly within the junction box and reattach the cover. Check to make sure the cover isn’t pinching any wires.

  8. Make sure the power cord doesn’t become pinched underneath when you slide the dishwasher in place.

The GE dishwasher power cord is universal and fits most leading brands of dishwashers. You should verify, though, what type of power cord you need when you purchase your dishwasher.

I have concrete countertops and was able to move one section to allow better access for this installation. Thus, I installed the power cord first, then plugged the cord into the outlet as I slide the dishwasher in place. You might not have the option to move your countertop out of the way. Therefore, will likely need to plug the cord into the outlet, run the cord to the cabinet opening, slide the dishwasher in place, then install the cord within the junction box.

Additional Installation Notes

  • NOTICE: Be sure to disconnect power to the dishwasher outlet before beginning the installation process!
  • Don’t run the cord into the junction box without strain relief. If your power cord kit doesn’t include it, you’ll need to buy a clamp connector.
  • After you match the wires and twist the exposed ends, cut them down with your pliers so the ends are sticking out about a 1/2″ away from the insulation. Then tightly twist on the wire nuts. You want the wire nuts to completely cover the exposed wire.
  • Tug lightly on the installed wire nuts to make sure they are firmly attached. You don’t want the wire nuts to be loose.
  • Tuck the wires neatly within the junction box before reattaching the junction box cover. Don’t allow the cover to pinch the wires.
  • Verify that the power cord doesn’t become pinched underneath as you slide the dishwasher in place.
