How To Soundproof Your Dishwasher?

You want to run you dishwasher but you dread the noise that comes with the task ahead. Its 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 neighbor’s.

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 noise begins to develop from your dishwasher. This is fixed at the bottom of the dishwasher to prevent noise generation from the base.

Here is how:

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 in 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 allows for the absorption of sound making it a very efficient sound insulator. The strand mat is most 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 in 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:


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


  • Bring out the dishwasher machine from the cabinet.
  • Measure the right side and top of the dishwasher.
  • Cut out the exact measurement from floor mat (sound proofing mass loaded vinyl) to cover the left and right sides (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)

  • Check for space between the machine and the cabinet
  • If the space is substantial, apply soudproofing mat on wood moulding and place between the space.
  • Hold the wood moulding in place with household adhesive to muffle sound generated from vibrations between the dishwasher and the cabinet.

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
