You might have faced the problem of your dishwasher moving or shaking when it runs, and it feels unsafe or annoying. You want your dishwasher to stay firmly in place under the countertop so it works well and lasts long. In this article, I will show you exactly how to secure a dishwasher under a countertop. You will learn the simple and effective ways to keep it safe and steady, so you don’t have to worry about it moving again.
Prepare Your Workspace and Gather Tools
Before you start, it is very important to prepare your workspace well. You need to make sure you have a clean and safe area to work. Clear everything under the countertop and around the dishwasher spot. This gives you space to move and fix the dishwasher without any problems.
Next, gather all the tools you will need. Usually, you will need a screwdriver, a drill, some screws, and possibly brackets or straps designed for dishwashers. Make sure the screws are the right size for your dishwasher and countertop. If you have a manual for your dishwasher, check it for any special parts you might need.
When working in tight kitchen spaces, good lighting is also important. Use a flashlight or a small lamp so you can see what you are doing clearly. You might want to wear gloves to protect your hands from sharp edges.
Prepare by turning off the dishwasher and unplugging it from the power source. Also, turn off the water supply to avoid leaks while working. Finally, pull the dishwasher out a little bit to give yourself more room, but be careful with the hoses and wires connected behind it.
- Clear the area under and around the countertop.
- Gather screwdriver, drill, screws, brackets, straps.
- Check dishwasher manual for special parts.
- Use good lighting and wear gloves.
- Turn off power and water supply.
- Pull dishwasher out carefully without damaging hoses.
Check Dishwasher and Countertop Fit
Now that your workspace is ready, the next important thing is to check how your dishwasher fits under the countertop. Sometimes dishwashers can be slightly bigger or smaller than the space available. This can cause problems if you try to force it in or don’t secure it properly.
Measure the height, width, and depth of the dishwasher first. Then measure the space under your countertop where the dishwasher will go. Make sure there is enough space for the dishwasher to slide in easily but not too much space so it moves around.
If the dishwasher is too tall, you may need to adjust the legs or feet of the dishwasher. Most dishwashers have adjustable feet that you can turn to raise or lower the height. This helps the dishwasher sit flush under the countertop without pushing too hard against it.
Also, check the countertop’s bottom edge. It should be smooth and strong enough to hold the dishwasher. If the countertop edge is weak or damaged, you may want to fix or reinforce it before installing the dishwasher. This helps prevent future problems with securing the dishwasher.
- Measure dishwasher height, width, and depth.
- Measure space under countertop carefully.
- Adjust dishwasher feet for correct height.
- Check countertop bottom edge for strength.
- Repair or reinforce countertop edge if needed.
Use Mounting Brackets or Straps to Secure Dishwasher
One of the best ways to secure a dishwasher is to use mounting brackets or straps. These small metal or plastic pieces attach the dishwasher firmly to the countertop or cabinet. They stop the dishwasher from moving forward, backward, or side to side when it runs.
Start by locating the mounting points on your dishwasher. These are usually near the top or sides of the dishwasher frame. The dishwasher manual will show you exactly where they are. Then, find matching spots under the countertop or inside the cabinet where you can attach the brackets or straps.
Use screws to fix the brackets securely. If you are fixing to a wooden cabinet, use wood screws. For metal countertops or cabinets, use the correct metal screws or bolts. Make sure the brackets or straps are tight but do not over-tighten and damage the dishwasher or countertop.
If your countertop is stone, like granite or marble, drilling might be hard or not possible. In this case, use special adhesive brackets or heavy-duty straps that stick or clamp to the dishwasher and cabinet sides.
- Find dishwasher mounting points from manual.
- Locate matching points under countertop or cabinet.
- Use correct screws for wood or metal.
- Tighten brackets firmly but carefully.
- Use adhesive brackets or straps for stone countertops.
Level the Dishwasher Correctly
A dishwasher that is not level can cause many problems, like poor cleaning, water leaks, and even damage to the machine. It is very important to make sure your dishwasher is level on all sides before securing it fully.
Use a bubble level tool to check the dishwasher’s position. Place the level on the top front edge of the dishwasher. Adjust the feet or legs by turning them until the bubble is centered. Then, check the side-to-side level by placing the bubble level on the sides of the dishwasher.
If you find the dishwasher is tilting forward or backward, or leaning to one side, fix it by adjusting the feet more. Some dishwashers have four adjustable feet, one at each corner. Keep checking with the level after each adjustment until it is perfectly flat.
A well-leveled dishwasher will fit better under the countertop and work more efficiently without shaking or sliding.
- Use a bubble level on the top front edge.
- Adjust dishwasher feet until bubble is centered.
- Check side-to-side level with the bubble level.
- Adjust all feet to stop tilting or leaning.
- Confirm dishwasher is perfectly flat and stable.
Secure Water and Power Connections Safely
While securing the dishwasher itself is important, you also need to take care of the water and power connections. Loose or poorly connected hoses and cables can cause leaks, shorts, or even fires. These problems can damage your kitchen and dishwasher.
Start by checking the water supply hose. Make sure it is connected tightly to both the dishwasher and the water valve. Use a wrench to tighten the hose connectors but don’t force them too much. Over-tightening can cause cracks or damage the connectors.
Next, check the drain hose. It should be properly placed in the drain pipe or garbage disposal. The hose must not be bent or pinched because this will stop water from flowing out, causing leaks or flooding.
For the power cable, ensure it is plugged into a grounded outlet. Avoid using extension cords, as they can be unsafe for dishwashers. The power cable should be placed where it will not get wet or damaged. If you are not sure about electrical connections, it is best to hire an electrician.
- Check water supply hose tightness with a wrench.
- Ensure drain hose is properly placed and not bent.
- Use grounded electrical outlet, avoid extension cords.
- Keep power cable away from water and damage.
- Hire professional help if unsure about wiring.
Test the Dishwasher After Securing
Once everything is secured, it is time to test your work. Push the dishwasher fully under the countertop and tighten any final screws or brackets. Check that the dishwasher does not move when you push or pull it gently.
Plug in the dishwasher and turn on the water supply. Run a short wash cycle to make sure everything is working well. Listen for any unusual noises or vibrations. Watch for leaks around the water connections and under the dishwasher.
If you notice any problems, like water leaks or shaking, turn off the dishwasher and fix the issue before using it again. Sometimes small adjustments in tightening screws or leveling feet are needed after testing.
Regularly check your dishwasher to make sure it stays secure and safe for many years to come.
- Push dishwasher fully under countertop.
- Tighten any remaining screws or brackets.
- Run a short wash cycle to test function.
- Check for leaks and unusual noises.
- Fix problems before regular use.
- Keep checking dishwasher security regularly.

Frequently Asked Questions (FAQs)
Is it necessary to secure a dishwasher under the countertop?
Yes, it is necessary to secure a dishwasher under the countertop to prevent it from moving or shaking during operation. If not secured, the dishwasher can slide out when the door is opened or while washing, which can cause damage to the machine, the surrounding cabinets, or even cause injury. Proper securing also helps the dishwasher work more quietly and efficiently by reducing vibrations. Securing prevents leaks by keeping hoses and connections stable. Most dishwashers come with mounting brackets or instructions for securing, which should always be followed for safety and performance.
Can I secure a dishwasher without drilling?
Yes, you can secure a dishwasher without drilling, but it depends on the countertop and dishwasher design. If you have a stone or delicate countertop where drilling is not possible or recommended, you can use heavy-duty adhesive brackets or metal straps that clamp around the dishwasher and cabinet sides. These provide strong hold without damaging the countertop. Another option is using anti-slip mats under the dishwasher feet to reduce movement. However, these methods may not be as strong as drilling and screwing brackets in place, so they are better for light securing or temporary setups.
Do I need special tools to secure a dishwasher?
You don’t usually need many special tools to secure a dishwasher. The basic tools like a screwdriver, a drill (if you are drilling holes), a wrench for water hoses, and a bubble level are enough for most jobs. If you use special adhesive brackets, you might need cleaning supplies to prepare surfaces for the adhesive. Some dishwashers come with a mounting kit that includes brackets and screws, which reduces the need for extra tools. If you are unsure about electrical or plumbing work, calling a professional is always safer.
Is it safe to use an extension cord for dishwasher power?
No, it is not safe to use an extension cord for a dishwasher. Dishwashers require a strong and stable power connection, and extension cords can cause overheating, power loss, or electrical shorts. They may not handle the dishwasher’s power needs properly, which can be dangerous and damage your appliance. It is best to plug the dishwasher directly into a grounded outlet installed by a professional. If the outlet is too far, have an electrician install a proper one near the dishwasher.
Can I adjust dishwasher feet after installation?
Yes, you can adjust the dishwasher feet even after installation. The feet are designed to be adjustable so you can level the dishwasher perfectly. If you notice the dishwasher is shaking or not draining water properly, adjusting the feet can often fix the problem. To adjust, gently turn each foot clockwise or counterclockwise until the dishwasher sits level on the floor. It is easier to adjust feet when the dishwasher is pulled out slightly, so you may need to pull it forward a bit to reach the feet.
Do I need to turn off water and power before securing a dishwasher?
Yes, you should always turn off the water supply and power before securing a dishwasher. This is important to avoid water leaks, electrical shocks, or damage while working. Turn off the water valve that supplies water to the dishwasher. Also, unplug the dishwasher or switch off the circuit breaker to cut the power. This ensures your safety and protects the dishwasher from damage during installation or securing.
Is it okay if the dishwasher touches the countertop?
No, the dishwasher should not press hard against the countertop. It should fit snugly but with a small gap or even surface contact without pushing hard. If the dishwasher presses too hard, it can damage the countertop, dishwasher frame, or cause vibrations. Adjust the dishwasher feet to make sure it sits flush without force. The countertop should support the dishwasher but not squeeze or bend it. Proper fit helps keep the dishwasher secure and working well.
Can I secure a dishwasher to cabinets instead of the countertop?
Yes, you can secure a dishwasher to the cabinets around it instead of the countertop. Some kitchens do not have a solid countertop or have stone countertops that are hard to drill. In such cases, mounting brackets or straps can be attached to the side or back of the cabinet frame to hold the dishwasher in place. This method is just as strong if done correctly. Always follow dishwasher manufacturer instructions for mounting locations and use the right screws or brackets for cabinet material.
