Benefits of a Dishwasher Insulation Blanket

Having an insulation blanket for your dishwasher does so much more than just dampen the sound from the dishwasher.

Here are some of the reasons why you need an insulation blanket for your dishwasher.

Sound Dampening
An insulation blanket will help reduce the level of noise that your dishwasher makes when in operation.

During a wash cycle, the spraying water, the drain and the humming of the dishwasher parts all contribute to the amount of noise that the machine makes.

With an insulation blanket, this sound is reduced significantly.

Thanks to improved sound dampening technologies, it is possible to have the dishwasher running and not interrupt any conversations. 

Protection from heat, steam, and water
During a wash cycle, the dishwasher can get extremely hot. This is because the machine uses hot water in each cycle.

The heat, together with steam and water from the dishwasher can cause damage to the surrounding wooden parts as well as the floor.

Having an insulation blanket around the dishwasher helps to reduce the impact on the surfaces as it provides a protective layer.

Reducing vibration
It is quite common for the dishwasher to vibrate a bit when in use.

Because many dishwashers are usually installed in between cabinets, having an insulation blanket around the machine will help to keep it in place.

You may also add some insulation on the doors to keep the front from rattling too much. 

What to consider when buying a Dishwasher Insulation Blanket?

Most dishwashers usually come with pre-packaged insulation. The insulation is usually made from fiberglass and is designed to fit the dishwasher purchased.

However, most people usually mistake this for packaging material and throw it away.

Pre-packaged insulation is usually quite thin. Because it is made to fit that particular dishwasher, it is usually the best insulation that you can use.

High-end dishwashers often come with a thicker layer of insulation.

This means that if you want better insulation for your appliance, you may want to consider purchasing a high-quality dishwasher machine.

You may find that you need some more insulation for your dishwasher.

Here is what you need to consider before you purchase another dishwasher insulation blanket:


Be sure that the insulation blanket you want to purchase will fit your dishwasher perfectly.

Built-in dishwashers are usually installed to fit in perfectly and there may not be enough room for additional insulation.

Before you purchase an insulation blanket, remove the dishwasher from its position and take measurements of whatever additional space there is.

This will help you determine the size of insulation blanket you need.

Insulation material

Dishwasher insulation blankets are made from different materials.

Having an understanding of these materials and how they work will help you make a better decision.

Common materials that are used to make dishwasher insulation include fiberglass, felt, foam.

Newer insulation materials such as ceramic fiber provide better insulation against sound, heat, and vibration.

Dishwasher Insulation DIY Guide

Soundproofing your dishwasher is quite easy and you can quickly do it yourself. Here is a quick guide to show you what exactly you need to do.

Step 1: Unplug the dishwasher

You cannot work on the dishwasher while it is still connected to the power and water lines.

Unplug the power plug from the socket first and then use a wrench to close the water valves tightly. Proceed to dis-attach the water lines and other lines once this is done.

Step 2: Unmount the dishwasher from the cabinet

Figure out where the dishwasher is mounted to the cabinet by finding the screws that keep the dishwasher attached to the countertop.

Unscrew them to unmount the dishwasher from the cabinet. This may take some effort so an extra pair of hands can come in handy.

Step 3: Discard the old insulation

Removing the old insulation will require that you use pliers.

This will be to help detach the rivets that hold the insulation in place. When doing so, be careful not to damage the rivets as you are going to use them to attach the new insulation.

Step 4: Replace the insulation wrap

Simply place the new insulation over the dishwasher and attach it into place using the rivets and pliers.

Depending on the dishwasher insulation blanket that you bought, there should be some installation guide in case you get stuck at any point.

Step 5: Place back the dishwasher

Once you are done soundproofing your dishwasher, all that is left to do is mount it back to the cabinet.

Be sure to plug back the power and water lines correctly before screwing the dishwasher back into place.
