Dishwasher insulation is the solution to the noises. An insulation blanket will do an excellent job, but you should know how to pull it off for the best outcome. We will take you through the topic of dishwasher insulation, giving you all the necessary info you should know about this accessory.

Why You Should Insulate Your Dishwasher

We start by showing you the benefits of getting an insulator for your dishwasher.

Silencing the Sound of Running Water

The sound of running water can be quite a nuisance when operating the dishwasher. You sometimes want to stay far from this appliance when it runs to get a piece of mind. The insulator steps into the equation, and helps dampen these sounds, which include gaggling, flushing, and buzzing of the machine.

While you may occasionally hear some noises, they are bearable. Padding the dishwasher at the back and sides will have a significant effect on noise reduction. For efficiency, it is also advisable to pad the frontal area.

Do Away with Vibrations

Vibrations are a mainstay with most dishwashers, especially the older models. When running, you notice some shaking, extending to surrounding furniture pieces and installations in the kitchen. It becomes worse if you have a wooden floor as the vibrations become more pronounced.

The shock-absorbing qualities of dishwasher insulation help to reduce vibrations. It reduces the trembling to manageable levels. Check the condition of this equipment if there is still excessive shaking because it could require some maintenance.

Offers Protection Against Water, Steam, and Heat

The dishwashers operating cycles produce heat and water, which you should control. Heat can damage supporting structures or cause overheating of the appliance; thus, reducing its service life.

Water can lead to mildew and mold growth. The growth of fungi degrades wooden structures and may produce an unbearable musty smell.

Dishwasher insulation acts as a barrier, preventing heat and water from escaping. You bid goodbye to the problem of worn-out surrounding structures.

How to Choose the Best Dishwasher Insulation

After looking at the role dishwasher insulation plays, you see how crucial it is. An issue most people have is selecting the right accessory for the dishwasher.

When selecting the insulation material, be keen on size. The width should be equal to or more than that of the dishwasher. You should get the appliance’s measurements to be sure.

Additionally, check on the thickness, where the thicker, the better. You should be able to slide the insulated kitchen equipment with ease back into place.

The insulator material is also crucial. Material such as cotton will do an excellent job in dampening sound, but it is prone to deterioration due to being damp for extended periods. The musty smell might be more pronounced with time. It is, therefore, advisable to go for polyester instead.

How Much Insulation Should You Get?

Back to the measurement factor, your figures should be accurate. You factor in the width, which covers the top section, then three heights for all the sides. The figure you get represents the least amount of insulation to get. The more, the better, as it will cover the parts lost in folding and cutting.

The standard height for most dishwashers is around 35 inches, while the width is 24 inches. 100 inches will adequately cover two sides and the top. If you also need to cover the back area, add an extra 35 inches.

Installation of Dishwasher Insulation

After looking at the review, you have an idea of which product to pick. With the product on your hands, you have to deal with another hurdle, installation. An easy way to go about it is by hiring a handyperson to fix it for you. However, this might be expensive, and further dig into your finances.

You can put your DIY skills to practice by handling the installation yourself. Keenness is a must, lest you end up with an undesirable outcome. Stick on as we take you through the steps of installing the dishwasher installation.

1. Check the Connections

Start by inspecting the connections of the dishwasher in the cabinet. Some have screws to secure them in place, while others rely on the water and electrical connections for anchorage. An inspection gives you an idea of the tools you need to use.

You will be lucky if the connections are not that firm, as you simply wiggle the appliance from its chamber. Also, you have to check the length of the power cord and water pipes. If long enough, installing the insulation material will be more convenient.

2. Disconnect the Dishwasher from Its Connections

The next step is disconnecting the dishwasher from its connections before working on it. After establishing the nature of the power cords and water pipes, you can proceed free of any hassles with this step.

Locate the dishwasher’s power switch and turn it off. Then, look for the piping valve and shut it to stop the water flow. This part can be really tricky, as any hitch can end up being very messy. Do not hesitate to ask for help if you cannot pull it through.

Loosen the screws that secure the appliance to the support structure. You have to open the door to access the upper edge screws. The dishwasher is now ready for removal from the supporting cabinet. Retract the front legs of this utility with a pair of pliers to make the ejection process easy.

Wiggle the equipment out gently to prevent any damage. You can put cardboard under the front legs to prevent scratches on the floor.

3. Covering the Dishwasher with an Insulator

With the kitchen utility out, you are now set to work on it. Remove the insulation material that the dishwasher initially had to put in the new one. Take measurements of the dishwasher and cut the insulator blanket to match the dimensions.

You may use tape or screws when wrapping, but be careful not to block the vents on the sides. Once done, you put the dishwasher back in its original place and fix all water and electrical connections.

Test your efforts by running the dishwasher. If you did everything correctly, you won’t notice any noises. If there is no change, you should contact a professional to check if there are any underlying issues.

Alternatives to Dishwasher Insulation

What alternatives can I consider apart from dishwasher insulation? You may implement several measures to avoid sounds and vibrations from this appliance. Sound-deadening mats do an excellent job if placed appropriately.

Soundproofing blankets are another ideal accessory to bank on. You put the blankets over the appliance to absorb sounds and vibrations.

Optionally, you may consider getting a quiet dishwasher. While it may cost more than the standard dishwasher, you won’t have to deal with the noises anymore.

An affordable way to go with the noise problem is to keep the dishwasher in a far-off room, which you can lock when the appliance runs. While it seems like a short-term solution, it can hold you down for some time until you get a permanent solution.
