Why is my dishwasher so loud?
It’s not rocket science to determine the problem with the dishwasher. Because a majority of consumers have faced the same issue. Here are some of the common instances for your dishwashers to make a loud noise.
1. Faulty circulation pump
The circulation pump is one of the primary reasons for supplying the water from the source towards the machine. When the device won’t function properly, then there is a fault at the circulation pump. One of the common instances that you can find the cause for faulty circulation pump would be lack of water supply from the spray arms. This way you will easily come to know whether the circulation pump is at fault or not.
2. Damaged motor
The motor of the dishwasher is primarily responsible for the complete operation of the home appliance. It is like the heart of the device which knows how to function and clean out the utensils. Whenever there is any problem with the motor or any damage, you can observe that the dishwasher starts to leak. Through this, you can see if there is an actual fault with the motor and seek assistance from technical experts.
3. Problem with the drain pump
The drain pump is a primary part when it comes to letting out the water from the machine. And when the drain pump is damaged due to lack of maintenance or getting frequently blocked with leftover food items, it decreases the performance of the machine and the loud noise starts to arise. The possible solution for this problem would be cleaning the dishwasher and the drain pump regularly. If the issue persists, you may need to replace it.

4. Source of water
The source of water is the section where the water is passed through the dishwasher. And when the dishwasher has been used for many years, the inlet valve starts to malfunction. It can be because of the extensive usage that makes it hard for water to pass through the inlet valve. This is one of the most primary reasons for which you can hear the loud noise made by the dishwasher.

5. Broken spray arm
The spray arm is primarily responsible for supplying the water and cleaning out the utensil from the machine. And when it has been broken or has been faced with any external damage due to the utensils, it starts to make a loud noise. You need to carefully evaluate whether there is any damage to the spray arms and fix it accordingly by either repairing it or replacing it.
6. Sealant is worn out
The sealant on the interior parts of the dishwasher can be worn out. And due to this, the machine starts to make a loud noise. You can try disassembling the dishwasher and check whether any part has been detached or not properly fixed. Inspect for every part whether there are any cracks or damages that need to be addressed out.
7. Defective solenoid operated diverter
The solenoid valve facilitates draining the water from the dishwasher. If you can notice that there is any damage caused on the drain valve solenoid, you can notice that the dishwasher starts to make a sound. It is one of the primary components that works closely with the drain impeller and the filter. They are usually found on the bottom of the side sections of the motor pump.
What are the reasons for dishwashers to make a sound?
There are many reasons for resources to make sound, but here I am going to shortlist some of the major causes.
1. Age of the dishwasher
The age of the dishwasher is one of the most primary reasons to make a sound. As you all know that the electrical home and kitchen appliances won’t last more than a decade. So if your machine is more than 10 years old, then the probable cause can be the malfunction of parts due to its age.

2. Improper usage
If you or any other family member do not use the dishwasher properly, then it automatically damages the internal part and causes a loud noise. This is the reason you need to operate the dishwasher with care and perform all the precautionary measures before using the machine. One of the common instances is that consumers do not clear the leftover food debris from the plate and directly place it in the machine. The second instance can be not using the recommended dishwasher detergent. Likewise, there are many factors for improper usage that lead to damage and generate loud noise.
3. Fluctuation in Electric Supply
When there is any fluctuation in Electric Supply, it can be either high voltage or lower outage. Both can cause a heavy toll on the dishwasher. Because the machine will not be able to sustain the fluctuation and the motor pump gets damaged. That is the reason you need to prefer a dishwasher that is inverter-based or see that you don’t run the machine when there are power fluctuations.
How to check the issue with the dishwasher motor pump?
A dishwasher motor pump is one of the most probable causes for the machine to make a loud noise. To inspect the part and reach a conclusion, you need to test for the possible issue. You can take the help of a multimeter that lets you know whether there is any problem with the pump.
To begin this process, you need to turn off your dishwasher before you start initiating this process. Alternatively, you also need to check whether there are any other electrical devices associated with it. You should detach the cables and ensure everything is turned off.
The next step that you have to do here is to detach the pump from the machine. You can easily find the pump at the bottom surface of the dishwasher. Then you need to proceed by testing the pump using the multimeter. If you observe the reading on the meter for zero around that, then it means that the pump is free from any problem. You can verify the process by cross-checking the terminals.
How to check for any issues in the spray arm?
The spray arm is another popular instance for the dishwasher to make a loud noise. The process is as similar as you checked for the issues with the motor pump.
To begin this process, turn off the dishwasher and remove the power cables.
Later you need to check the spray arm and see if it is coming in contact with the interior parts of the dishwasher. It needs to be freely oscillating within the machine and the spray arm should be oscillating at a constant cycle.
You can also check whether there is any wear and tear caused by food plates on spray arms. If you find any such issues, you may need to replace them as it is very hard to repair the spray arms.
Concluding thoughts
If you look at the above scenario, the possible solution for fixing the problem is to completely replace the component. Because it is very hard to repair those parts and even if you are able to manage to repair them, it won’t work for a longer time. The best practice before you fix any problem would be to check whether the machine is still under the warranty period. As it will be serviced for free of cost.
You can also take the help of expert technicians who can fix it without any hassle. I hope that now you are aware of why is my dishwasher so loud. Let me know if you have any other queries in the comment section below.
