To replace a dishwasher, turn off and disconnect the utilities, slide the dishwasher out, prepare the new dishwasher, connect the utilities, position the appliance, restore the utilities, and attach the front panel. You need a screwdriver, a wrench, pipe elbows, threading tape, nuts and an assistant.
- Turn off and disconnect the utilities
Shut off the dishwasher's water supply and electrical power. Unscrew its front panel, and set the screws in a safe place. Use a wrench to disconnect the water pipes, and then remove the waste line clamps.
- Slide the dishwasher out
Remove the clips fastening the appliance to the counter, and set them aside. Slowly pull the dishwasher out, and move it out of the work area.
- Prepare the new dishwasher
With the help of an assistant, lay the new dishwasher on its back. Apply threading tape to its water pipe, and screw on a pipe elbow. The elbow must point to the back side of the dishwasher. Return the appliance to an upright position.
- Position the appliance
Push the new dishwasher toward the counter. As you begin to slide it beneath the counter, have your assistant pull its waste line beneath the sink. Connect the waste line to the sink drain line.
- Reconnect the water and electricity
Push the dishwasher under the counter, and attach the water line. Tighten the connection with a wrench, turn on the water to check for leaks, and then shut it off. Connect the dishwasher's electrical lines to the existing wires by matching their colors, and then wrap the washer's grounding wire around the screw in the electrical box.
- Replace the front panel
Examine the base of the dishwasher, and adjust its feet until the appliance is level. Fasten the dishwasher to the counter with retaining clips, attach its access panel, and switch on the utilities.
