The Step-By-Step Guide to Wiring Glory

Clad in your DIY suit, you're now ready to wire a three-prong dishwasher plug. Perform this process with your hands and not some Thunderbolt, there are no revives or respawn points in real life. Let's fight dish grime with all our might!

Step 1: Power Down and Unplug

First, flip off the correct circuit breaker or remove the appropriate fuse to ensure the dishwasher isn’t supplied with power.

Step 2: Access the Terminal Box

Unscrew the base plate of the dishwasher, and you’ll likely find a metal box; this is the terminal box. Open up this box, and voila, you’re introduced to the wire ends.

Step 3: Your Power Cord Enters the Scene

Attach the strain relief to the power cord and thread it into the hole in the terminal box.

Step 4: Meet ‘n’ Greet with the Wires

Strip off any insulation from the wire ends on the power cord. Twist the power cord's white wire and the white wire from the dishwasher together, and lasso an orange or yellow wire nut over them. Repeat the process with the black wires.

Step 5: The Ground Wire Needs Love Too

Attach the green wire (ground wire) from your power cord to the dishwasher’s ground point using a grounding screw. Insulate all wires with electrical tape, if necessary.

Step 6: Reassemble the Terminal Box

Fit the wires back into the terminal box, screw the box safe and sound, and reattach the base panel. You're basically done!

Step 7: Can’t Keep it in—Plug it in!

Re-energize the circuit, plug that baby in, and give yourself a high-five (or a self-congratulatory clap, if you aren't much of a five-giver).

The Final Fanfare

Remember, with great power(cord) comes great responsibility. Keep your safety in mind at all times. If you remain calm, double-check your process, and follow these instructions, you can save the day and the party dishes!
