Things You'll Need
Most dishwashers connect to an inlet valve on your garbage disposal that transfers the water out of the dishwasher and out of the house through the plumbing in your kitchen. If you are removing your dishwasher, you must remove the dishwasher drain line from the inlet valve on your disposal. To ensure that water does not spill from the open valve after the drain line is removed, you must place a cap on the end of the inlet.
Go to the fuse box and turn off the breaker that supplies power to the dishwasher.
Remove the two screws on the bottom panel of the dishwasher, and then remove the bottom panel.
Turn off the dishwasher water supply valve, which is located under your sink, and then disconnect the water supply line from the dishwasher's water inlet valve, using an adjustable wrench. The water inlet valve is located on the left side of the bottom compartment of the dishwasher.
Remove the screws securing the junction box cover and then remove the junction box cover, which is located on the right side of the bottom compartment of the dishwasher.
Untwist the two wire nuts to separate the wires. Loosen the grounding screw and then remove the bare or green ground wire from the grounding post.
Loosen and remove the strain relief nut that secures the conduit cable through the rear of the junction box. If necessary, use a screwdriver to break the seal of the nut. Pull the conduit cable out of the junction box.
Remove the dishwasher drain hose from the disposal or drainpipe. To remove it, loosen the screw on the metal clamp and then pull the drain hose off the disposal or drainpipe.
Feed the drain hose through the cabinet and behind the dishwasher.
Place a pipe cap over the end of the disposal inlet or pipe to which the drain hose was connected.
Tighten the screw on the metal clamp surrounding the pipe cap to secure the cap to the disposal or pipe.
Remove the two mounting screws from the top of the front of the dishwasher that secure the dishwasher to the underside of the countertop.
Turn the leveling legs on the dishwasher counterclockwise to raise them.
Slide the dishwasher out from underneath the cabinet.
