Replacing a dishwasher typically involves a few steps. Here's a general guide on how to change a dishwasher:

Note: Before starting, make sure to turn off the power to the dishwasher at the circuit breaker and shut off the water supply to the dishwasher.

1. Gather Your Tools and Materials:

  • New dishwasher

  • Screwdriver

  • Adjustable wrench

  • Pliers

  • Teflon tape

  • Level

  • Towels and a bucket (to catch water)

2. Prepare the New Dishwasher:

  • Unbox the new dishwasher and read the installation instructions that come with it. This will provide specific guidance for your model.

3. Disconnect the Old Dishwasher:

  • Open the dishwasher door and remove the screws holding it in place to the countertop (typically found on the sides or top).

  • Slide the old dishwasher out from under the counter.

  • Locate the power cord or electrical wiring. Disconnect the power by removing the wire nuts and separating the wires. It's essential to turn off the power at the circuit breaker first.

  • Turn off the water supply valve under the sink and disconnect the water supply line from the dishwasher. Have a bucket and towels handy to catch any remaining water.

4. Remove the Old Dishwasher:

  • If the old dishwasher is still connected to the drain, disconnect the drain hose or tube from the sink drain or garbage disposal.

  • Carefully pull the old dishwasher out from under the counter, being mindful of the water and electrical lines.

5. Prepare the New Dishwasher:

  • Install any necessary brackets or hardware that came with the new dishwasher to secure it to the countertop.

  • If your new dishwasher didn't come with a power cord, you may need to transfer the old one if it's compatible. Follow the manufacturer's instructions for this.

  • Apply Teflon tape to the threaded end of the water supply line.

6. Install the New Dishwasher:

  • Slide the new dishwasher into the space under the counter.

  • Connect the water supply line to the water inlet on the dishwasher and tighten it with an adjustable wrench.

  • Connect the drain hose or tube to the sink drain or garbage disposal.

  • Secure the dishwasher to the countertop by screwing it in place (refer to the installation instructions).

7. Connect the Electrical:

  • Connect the electrical wires using wire nuts, following the manufacturer's instructions for your specific model.

  • Ensure the wires are properly secured and tucked away to avoid interference with moving parts.

8. Check for Leaks:

  • Turn the water supply back on and check for any leaks around the water connections. If you see any leaks, tighten the connections further.

9. Level the Dishwasher:

  • Use a level to ensure the dishwasher is sitting level both side-to-side and front-to-back. Adjust the leveling feet as needed.

10. Test the Dishwasher:

  • Turn on the power at the circuit breaker.

  • Run a test cycle to ensure the dishwasher is working correctly.

11. Clean Up:

  • Dispose of the old dishwasher following your local regulations.

  • Clean up any mess or debris left behind during the installation.

12. Read the Manual:

  • Review the user manual for your new dishwasher to understand its features and maintenance requirements.

Please note that these steps are a general guideline. Always follow the manufacturer's specific instructions provided with your dishwasher, as installation procedures can vary from one model to another. If you're unsure about any step in the process, consider hiring a professional installer to ensure the job is done safely and correctly.
