First Step

First of all, you have to turn off the power source and also remove the water source. It is for your own safety and vital for detailed inspection to find out the element that is creating the real problem in this situation.

Step Two

Now you have to remove the front panel and it is not really difficult. First of all, you have to open the door of the dishwasher and use the screwdriver to get the screws out from the inside. Close the door and easily open the front panel.

Step Three

Inspect the front panel of the dishwasher for any kind of dirt or debris. It is possible that something is stuck in there creating the problem. If the inside of the panel is clear then you have to purchase a sound-absorbing matting for the panel.

The length and the width have to be equal to the front panel so you can fit it in properly. Now fix the matting inside the front panel.

Step Four

The matting has to go inside the front panel properly. Watch out for the depth and make sure that it properly fits in. There shouldn’t be any kind of space in between because then there would be no benefit of the matting.

Take the screwdriver and fix the screws again. Wasn’t it easy? You have been able to fit in the sound-absorbent without any issue at all.

Step Five

Remove all the water lines from the dishwasher. Take the dishwasher out and remove it from the wall and the cabinets. You need a screwdriver here as well so keep it close. The door of the dishwasher can be used to pull out the whole thing from its place in a safe manner.

Step Six

Take the insulating blanket out of the dishwasher. It is mostly placed on top and on the sides. It is possible that the blanket has an issue because of continuous usage and it needs to be replaced. The effectiveness reduces with time and after a while, it starts creating noise. It is important to keep inspecting the blanket and if it needs a replacement you shouldn’t get late at all.

There is no technical knowledge required for replacing it because you just need to push it into the frame and it will get locked at its particular place.

Step Seven

Next step is to check the back of the dishwasher for the noise. It is possible that it hits the wall and creates noise so you have to apply soundproofing material at the back as well.

In order to do so, you will have to use the material according to the length of the dishwasher. You can also use strips of the material but it would take a lot of cutting so it depends on how you want to do it.

Step Eight

This is the final step of the process and now you are done with everything you can do so it is time to put the dishwasher back in its place. Use the screwdriver to put all the screws back and attach all the water lines along with the power supply and turn it on.

Now your dishwasher is back in action and you can start washing dishes without any kind of noise. Try to use a dishwasher basket that is suitable for the machine and doesn’t produce any rattling noise. You can use different kinds of baskets according to the dishes you use and keep replacing them.
