How To Soundproof Your Dishwasher

You want to run your dishwasher but you dread the noise that comes with the task ahead. It’s so hard having meaningful conversations over the sound of a ‘truck revving’ in your kitchen and any time you have dinner in the evenings you have to pile those dishes for the following morning because you might be disturbing your neighbors.

Opting for a new mid to high-range dishwasher would easily solve your problem since they are usually quieter. However, if you don’t have the cash for a more expensive dishwasher, you can still find ways of quietening your dishwasher.

Some dishwashers come with a sound upgrade kit which may be purchased when the noise begins to develop from your dishwasher. This is fixed at the bottom of the dishwasher to prevent noise generation from the base.

How To Soundproof Your Dishwasher


There are so many inexpensive materials out there that can efficiently insulate your old machine for noise control. Styrofoam and several soundproof foams are easily available on the market for that purpose.

Another option is to fit fiberglass insulation into your machine. Fiberglass also called glass-fiber reinforced plastic is a lightweight material with glass fiber as its base. It is produced by forcing molten glass through microbial holes through a process called pultrusion.

The air pockets within the material allow for the absorption of sound making it a very efficient sound insulator. The strand mat is ideal and can be measured to 2″ and fixed close to the base of the dishwasher to control noise from your machine.


Always use protective gear when handling fiberglass. Particles of glass may easily be dislodged and float into your eyes, nose, or mouth. This is may prove to be extremely harmful.

Here are a few steps to help control noise from your dishwasher:

Step 1:

Take off the front door cover of your dishwasher by unscrewing the bottom screws. Then gently lift off the panel and place it aside for re-fixing afterward.

Remove any material between the inner door and the panel you have taken off.

Measure accurately the space in between the panel and the inner door and cut out a slightly thinner measurement from the sound absorbent mat.

Attach one end of the material to the end of the door and apply household adhesive or contact cement (depending on which is available) to hold the soundproof mat in place.

Step 2:

Bring out the dishwasher machine from the cabinet.

Measure the right side and top of the dishwasher.

Cut out the exact measurement from the floor mat (sound proofing mass loaded vinyl) to cover the left and right sides (the left side is the same measurement as the right obviously) and the top as well.

Hold the material in place with the help of household adhesive (you may leave the back of the unit)

Step 3:

Check for space between the machine and the cabinet

If the space is substantial, apply soudproofing mat on wood molding and place it between the space.

Hold the wood molding in place with household adhesive to muffle sound generated from vibrations between the dishwasher and the cabinet.

How To Soundproof a Noisy Dishwasher?

There are a few ways to soundproof a noisy dishwasher. One is to add insulation around the dishwasher, which will help to absorb some of the noise. Another is to use sound-dampening mats or pads under the dishwasher, which will help to reduce the vibrations that cause noise. Finally, you can also try sealing any gaps around the dishwasher with caulking or weatherstripping to further reduce noise.

How To Make My Dishwasher Quieter?

There are a few things you can do to make your dishwasher quieter. First, check to see if there are any loose parts that may be causing the noise. Next, make sure the dishwasher is level – an unlevel dishwasher can vibrate and cause noise. Finally, try insulating the dishwasher with sound-proofing materials to help reduce noise.

Are all Dishwashers Noisy?

No, not all dishwashers are noisy. Some dishwashers are designed to be very quiet, and you may not even be able to tell when they’re running. However, some dishwashers can be quite loud, and you may want to avoid using them at night or when people are sleeping.

Is it Normal For a Dishwasher To Make Noise?

Yes, it is normal for a dishwasher to make noise. The dishwasher is equipped with a pump and motor that circulate water through the dishwashing cycle. You may hear gurgling or whirring noises as the water is pumped through the dishwasher.

Follow these outlined steps and you are sure to have a dishwasher sounding as good as new. Please feel free to leave comments or share your thoughts on the subject.
