The dishwasher may make a strange noise if the wash motor or circulation pump are damaged. The following methods can help you troubleshoot a faulty wash motor.

  • Using a screwdriver and a wrench, remove all of the screws holding the dishwasher in place. If there is a significant amount of rust, you can also use a mini-hacksaw.
  • Disconnect the main components from the wash motor. While disconnecting, pay attention to avoid damaging other parts of the dishwasher.
  • Inspect the status of the wash motor for any problems. Ensure you scrutinize all parts.
  • Use sealing tape or any other appropriate tape to seal the wash motor if it is cracked.
  • If any dirt or organic matter is clogging the wash motor, clean it and unclog it. Clean the motor with a suitable detergent.
  • After reinstalling the pump, test it to check if the problem has been fixed.

If the problem persists, replace the motor or the entire dishwasher.

2. Water supply to the Samsung dishwasher machine is insufficient

If there isn’t enough spraying water in the washer during a cycle, it will make some noises. First, inspect the Samsung dishwasher parts for any flaws once the water spraying in the dishwasher has decreased. After you’ve figured out what’s causing the high-pitched noise, follow the procedures below to fix the low water supply problem.

  • Before moving on to the next step, disconnect the dishwasher and inspect it thoroughly.
  • Some parts, such as the water inlet valve, must be thoroughly inspected to determine whether they are in excellent working order or damaged. Remove any dirt or organic matter that has clogged the water inlet valve using a thin brush.
  • To remove any trapped material, flush distilled vinegar down the inlet valve. Allow the distilled vinegar to sit for a few seconds, maybe thirty minutes.
  • Flush clean water down the water inlet valve to flush out any remaining vinegar.

If the high pitch noise persists, get assistance by taking the dishwasher to a local repair shop or considering replacing the entire dishwasher.

3. A faulty Samsung dishwasher spray arm

The spray arm could be loose, and when it hits the utensils in the dishwasher owing to faulty utensil loading, it makes a knocking or rattling noise. The spray arm will not rotate if there are too many utensils in the dishwasher.

To resolve the issues, make sure that dirty utensils are correctly loaded into the dishwasher. When the spray arm is loaded correctly, it can rotate freely during the cleaning operation. Replace the spray arm with a new one that fits your dishwasher if it breaks. Also, clean and arrange the utensils in their proper places before removing them from the dishwasher. Finally, to avoid clogging the spray arm, reposition the laden utensils tightly to the dishwashing bucket.

4. The ventilation fan has been damaged

b) Perform a thorough inspection of the ventilation fan to identify any issues. Consider moving on to the next stage if there are any flaws.

5. Dishwasher drain pump bad

During the washing operation, the Samsung dishwasher drain pump is critical for emptying filthy water from the unit. To use the dishwasher pump, turn on the dishwasher and engage the dishwasher pump to dirty water in the pump, allowing clean water to re-enter. When the dishwasher drain pump fails, strange noises can be heard while cleaning the utensils.

Equipment in the drain pump, such as glass fragments, bones, and an accumulation of undrainable dirt, among other things, can cause a malfunctioning drain pump. A broken drain pipe might also cause a defective drain pump. The steps for troubleshooting a faulty drain pump are outlined in the information below.

1) Inspect the drain pump for any problems. Examine the drain pump as well as the entire dishwasher.

2) Before starting the repair, disconnect the dishwasher and disassemble the drain pump.

3) If the dishwasher drain pump is packed with broken glass or other objects, clean it with the recommended agent, such as distilled vinegar.

4) Rinse the pump to remove any remaining vinegar and allow it to dry.

5) Replace the drain pump in its original location and test the dishwasher to determine if the problem has been rectified.

6) If the dishwasher drain pump is broken, replace it with a new drain pump compatible with the dishwasher. Also, make sure the new drain pump is of good quality and works properly.

7) If the problem persists, other dishwasher parts may be at blame, or the entire dishwasher may need to be replaced.

6. A faulty water intake valve is present

The water inlet valve is required because it permits clean water to enter the dishwasher. The water pouring into the dishwasher comes into contact with deforms during the wearing process, causing a loud buzzing and screeching noise.

To resolve the problem, disconnect the water inlet valve and examine it for any deformities. If the valve is new and damaged, consider repairing it yourself or hiring a professional to assist you. If the water inlet valve is too old and unfixable, replace it.

Frequently asked questions

  • What is the source of the odor in my Samsung dishwasher?

The most common source of Samsung dishwasher odors is a build-up of trapped food particles or grease. They can block your dishwasher’s filters, spray arm, drain hose, and other nooks and crannies. If these food particles are allowed to accumulate over time, they begin to smell and emit fishy or foul odors, which are transferable to your dishes. Bacteria accumulate, making your dishwasher a breeding ground for bacteria and mildew.

If your dishwasher has a musty or damp odor, it could be due to a kinked hose or clogged drain. If feasible, slowly remove the dishwasher from its compartment and check the hose and surround for damage.


When in use, the Samsung dishwasher may make some amusing noises. The only approach to solve the noise problem is to inspect all parts and repair them if they are defective. Fortunately, the information provided above demonstrates how to repair various dishwasher components.
