How to Lower a Dishwasher

Dishwashers have become an indispensable appliance in modern kitchens, but their installation can sometimes pose challenges. Whether you’re installing a new dishwasher or adjusting the height of an existing one, knowing how to lower a dishwasher correctly is essential. In this article, we’ll guide you through the process step by step, ensuring a hassle-free experience.

Assessing the Need for Lowering

Before you embark on the journey of lowering your dishwasher, it’s crucial to determine if it’s necessary. Common reasons for needing to lower a dishwasher include:

  • Counter Height Change: If you’ve recently replaced your countertops and they are lower or higher than the previous ones, your dishwasher’s height may no longer align.
  • Flooring Change: Altering the flooring in your kitchen can also affect the height of your dishwasher.
  • Accommodating Cabinetry: If you’re installing new cabinets or making adjustments to existing ones, the dishwasher’s height may need to be modified to fit seamlessly.

Gathering the Necessary Tools

To ensure a smooth process, gather the following tools and materials:

  • Adjustable wrench
  • Screwdriver
  • Level
  • Tape measure
  • Towels or rags
  • Plumber’s tape
  • Safety goggles
  • Work gloves

Safety Precautions

Safety should be your top priority during this project. Always:

  • Wear safety goggles to protect your eyes from debris.
  • Use work gloves to prevent injuries while handling sharp edges or heavy parts.
  • Turn off the power to the dishwasher and water supply before starting any work.

Turning Off the Power and Water Supply

Locate your home’s circuit breaker and turn off the power to the dishwasher. Additionally, shut off the water supply valve under the sink.

Removing the Dishwasher

  1. Open the dishwasher door and remove any items inside.
  2. Use the adjustable wrench to disconnect the water supply line and the drain hose from their respective connections.
  3. Carefully pull the dishwasher out from its space, taking care not to damage the flooring.

Adjusting the Legs

  1. Lay the dishwasher on its back.
  2. Locate the adjustable legs on each corner of the dishwasher.
  3. Use a screwdriver or a wrench to turn the legs counterclockwise to lower them. Measure the height as you go to ensure it aligns with your new requirements.

Reinstalling the Dishwasher

  1. Lift the dishwasher carefully and slide it back into its designated space.
  2. Ensure it’s level with the adjacent cabinets using a level.
  3. Reconnect the water supply line and drain hose.
  4. Turn on the water supply and check for any leaks.

Leveling the Dishwasher

To ensure the dishwasher is perfectly level:

  1. Place a level on the door or the top of the dishwasher.
  2. Adjust the legs as needed until the bubble in the level is centered.

Testing for Leaks

  1. Run a short cycle on the dishwasher and check for any leaks.
  2. If leaks are present, turn off the power and water supply, and recheck the connections.

Final Checks

Before calling it a day, make sure to:

  • Reconnect the power to the dishwasher.
  • Replace any items you removed from the dishwasher.
  • Give the exterior a quick wipe-down to remove any fingerprints or smudges.

Maintenance Tips

To keep your dishwasher running smoothly, remember these maintenance tips:

  • Regularly clean the filter and spray arms.
  • Check for loose connections or worn-out parts.
  • Avoid overloading the dishwasher.

Troubleshooting Common Issues

If you encounter problems with your dishwasher, such as unusual noises, poor cleaning, or drainage issues, consult your manufacturer’s manual for troubleshooting guidance.

When to Seek Professional Help

If you’re uncomfortable with any part of the lowering process or if you encounter complex issues, it’s best to seek professional assistance. Attempting complex repairs without experience can lead to costly damage.

Benefits of Proper Dishwasher Height

Properly adjusting your dishwasher’s height offers several benefits:

  • Improved aesthetics and kitchen design.
  • Reduced risk of leaks and damage.
  • Enhanced convenience and functionality.


Lowering a dishwasher to fit your kitchen’s specific requirements is a manageable DIY project if you follow the steps outlined in this guide.
