How to Fix a Broken Grounding Junction on a Dishwasher

Dishwashers, like many household appliances, connect to a household electrical circuit by means of two electrical conductors and a ground wire. While most appliances use an electric cord to connect to a power outlet, large appliances that are intended to stay in one place are often hardwired into an electrical branch circuit. If the electrical junction where the ground wire connects to the dishwasher is broken, this can pose an electric shock hazard and should be corrected quickly. Fortunately, such a break can be repaired using a few common household tools.

Screwdriver
Electrical pliers
Crimp-type ring terminals

Instructions

- 1
  Turn off the power to the dishwasher circuit at the circuit breaker or fuse box.
- 2
  Loosen and remove the grounding junction screw on the back of the dishwasher, generally located in a box or well sitting close to the floor. Remove the two ground wires from the screw. The ground wires from the electrical service may have green insulation or may be bare copper.
- 3
  Trim any frayed or broken edges off the damaged ground wire using the electrical pliers. Strip 1/2 inch of insulation from the end of this ground wire.
- 4
  Insert the bare wire into the ring terminal and crimp the terminal to the wire end using the pliers.
- 5
  Place the ring terminals at the end of both ground wires over the shaft of the grounding junction screw. Place the grounding junction screw into the screw hole and tighten the screw until it holds both ring terminals firmly against the dishwasher chassis.
