Why Leveling a Dishwasher Matters
Before diving into the “how-to,” let’s understand why leveling is essential. A dishwasher that isn’t level can suffer from uneven water distribution, leading to poorly cleaned dishes or water pooling inside the unit. Over time, this misalignment can strain the door, hinges, and motor, potentially causing costly repairs. According to appliance experts at Whirlpool, “Proper dishwasher installation—including leveling—ensures the appliance operates as designed and avoids unnecessary stress on its parts” [(( Whirlpool ))].
Now, let’s get started with the tools and steps you’ll need.

Tools and Materials You’ll Need
To level a dishwasher effectively, gather the following items:
- Adjustable wrench or screwdriver: For adjusting the leveling legs.
- Carpenter’s level (bubble level): To check for evenness front-to-back and side-to-side.
- Measuring tape: To ensure proper alignment with surrounding cabinetry.
- Shims (optional): Thin pieces of wood or plastic to stabilize uneven floors.
- Gloves and flashlight (optional): For comfort and better visibility under the unit.
Most dishwashers come with adjustable legs, but if yours doesn’t, shims will be your go-to solution.

Step-by-Step Guide to Leveling a Dishwasher
Step 1: Prepare the Dishwasher and Workspace
Start by turning off the power to the dishwasher at the circuit breaker to avoid any electrical hazards. If it’s a new installation, ensure the water supply is disconnected. Open the dishwasher door and remove the bottom rack to access the interior floor easily. Clear any debris from under the unit and ensure the floor is clean—this prevents false readings when leveling.
Step 2: Locate the Leveling Legs
Most dishwashers have three or four adjustable legs—two in the front and one or two in the back. These are typically found at the base of the unit and can be adjusted with a wrench or screwdriver. Check your owner’s manual for specifics, as designs vary by brand. For instance, GE Appliances notes, “The front legs can often be adjusted by turning them clockwise to raise or counterclockwise to lower” [(( GE Appliances ))].
Step 3: Check the Current Level
Place your carpenter’s level on the floor of the dishwasher (inside the unit) to assess its current alignment. First, check side-to-side by placing the level horizontally across the width. Then, check front-to-back by aligning it from the door to the back wall. Note any tilt—bubbles off-center indicate unevenness.
Step 4: Adjust the Front Legs
Using your wrench or screwdriver, turn the front leveling legs. To raise the dishwasher, turn clockwise; to lower it, turn counterclockwise. Adjust one leg at a time, then recheck with the level. Aim for the bubble to sit perfectly between the marked lines. If the back seems off but lacks adjustable legs, proceed to the next step.
Step 5: Address the Back (If Necessary)
For dishwashers with rear adjustable legs, you may need to pull the unit out slightly to access them—check your manual for guidance. If there are no rear legs, use shims. Slide a shim under the back edge of the dishwasher to lift it slightly, then recheck the level. Bob Vila’s experts suggest, “Wooden shims are great for minor adjustments—just tap them gently into place with a hammer” [(( Bob Vila ))].
Step 6: Fine-Tune and Test
Once the dishwasher is level side-to-side and front-to-back, push it back into its space (if you moved it). Ensure it aligns with the countertop and cabinetry—use a measuring tape if needed. Close the door and turn the power back on. Run a short cycle with no dishes to check for leaks or unusual noises, which could indicate further adjustments are needed.

Pro Tips for a Perfectly Leveled Dishwasher
- Check the Floor First: Uneven flooring is common in older homes. If your kitchen floor slopes, you might need to level the surrounding area or use thicker shims.
- Don’t Overtighten: Over-adjusting the legs can strip the threads or damage the base—turn gently and incrementally.
- Secure After Leveling: Once leveled, tighten any locking nuts on the legs (if present) to prevent shifting during operation.
- Recheck Periodically: Vibrations from regular use can throw off alignment over time, so inspect the level every six months or after moving the unit.

Additional Considerations
Installation Context
If you’re installing a new dishwasher, leveling is just one part of the process. Ensure proper plumbing and electrical connections are in place first, as these can affect positioning. For built-in units, confirm the cabinet opening is square—misaligned cabinetry can complicate leveling efforts.
Troubleshooting Existing Units
For an already-installed dishwasher, leveling might resolve issues like water pooling or noisy operation. The Spruce advises, “If your dishwasher rocks or wobbles when you push on it, it’s a clear sign it’s not level—don’t ignore it” [(( The Spruce ))].
Brand-Specific Variations
Different manufacturers may have unique leveling mechanisms. Bosch dishwashers, for example, often feature a rear leg adjustable from the front with a special tool included in the kit. Always consult your manual for tailored instructions.

Frequently Asked Questions (FAQ)
Q: How do I know if my dishwasher isn’t level?
A: Signs include water pooling at the bottom, uneven cleaning results, or the door not closing properly. You might also hear rattling or notice the unit wobbling when touched.
Q: Can I level a dishwasher without a carpenter’s level?
A: Yes, but it’s less precise. You can use a smartphone app with a leveling feature or observe water behavior inside during a cycle—just pour a cup of water in and see if it pools unevenly.
Q: What if my floor is uneven?
A: Use shims to compensate. For severe slopes, consider leveling the floor itself with a contractor’s help before installation.
Q: How long does it take to level a dishwasher?
A: For most people, it takes 15-30 minutes, depending on access and adjustments needed.
Q: Do I need a professional to level my dishwasher?
A: Not usually—it’s a DIY-friendly task. However, if you’re uncomfortable with tools or suspect structural issues, call a technician.
