Why Is My Samsung Dishwasher Humming? The Mystery Solved!

Samsung dishwashers are known for their efficiency, reliability, and quiet operation. However, like any appliance, they can sometimes develop problems, including humming noises. If you’re experiencing this issue with your Samsung dishwasher, don’t panic. In this comprehensive guide, we’ll explore the potential causes of the humming noise and provide step-by-step instructions to help you troubleshoot and resolve the problem.

Possible Causes of Humming Noise in Samsung Dishwashers

1. Faulty Drain Pump: A faulty drain pump can cause a humming noise during the draining cycle. The drain pump is responsible for removing water from the dishwasher after the wash cycle is complete. If the pump is malfunctioning, it may not be able to drain the water properly, resulting in a humming sound.

2. Obstructed Drain Hose: A blocked or kinked drain hose can also lead to a humming noise. When the drain hose is obstructed, it prevents the water from draining properly, causing the dishwasher to make a humming sound.

3. Worn-Out Motor Mounts: Over time, the motor mounts that support the dishwasher’s motor can become worn or damaged. This can cause the motor to vibrate excessively during operation, resulting in a humming noise.

4. Damaged or Loose Impeller: The impeller is a rotating part of the dishwasher’s wash system that helps to circulate the water. If the impeller is damaged or becomes loose, it can cause a humming noise during the wash cycle.

5. Faulty Control Board: In some cases, a faulty control board can also cause a humming noise in the dishwasher. The control board is responsible for managing the dishwasher’s various functions, including the motor and drain pump. If the control board is malfunctioning, it may send incorrect signals to the motor or drain pump, resulting in a humming noise.

Troubleshooting and Resolving the Humming Noise

1. Check the Drain Pump: To check the drain pump, first, ensure that the dishwasher is turned off and disconnected from the power source. Then, locate the drain pump, which is usually situated at the bottom of the dishwasher. Inspect the pump for any signs of damage or wear. If you notice any damage, replace the pump with a new one.

2. Inspect the Drain Hose: Next, inspect the drain hose for any kinks or blockages. Straighten out any kinks and remove any obstructions that may be blocking the hose. If the drain hose is damaged, replace it with a new one.

3. Examine the Motor Mounts: Check the motor mounts for signs of wear or damage. If the mounts are worn or damaged, replace them with new ones.

4. Inspect the Impeller: To inspect the impeller, you’ll need to remove the wash arm from the dishwasher. Once the wash arm is removed, you can access the impeller. Check the impeller for any damage or wear. If the impeller is damaged, replace it with a new one.

5. Test the Control Board: Testing the control board requires specialized knowledge and equipment. If you suspect that the control board is faulty, it’s best to contact a qualified appliance repair technician for assistance.

Preventive Maintenance Tips to Avoid Humming Noise

1. Regular Cleaning: Regularly clean the dishwasher’s filter and drain hose to prevent clogs and blockages.

2. Proper Loading: Avoid overloading the dishwasher, as this can put excessive strain on the motor and drain pump.

3. Use the Right Detergent: Use the recommended amount of detergent and rinse aid to avoid excessive foaming, which can strain the motor and drain pump.

4. Regular Maintenance: Schedule regular maintenance checkups with a qualified appliance repair technician to ensure that your dishwasher is functioning properly.
