Why Your Dishwasher Is So Loud (and What You Can Do About It)
What To Know

- The time required to replace a dishwasher motor varies depending on the model and the technician’s experience.
A noisy dishwasher can be a major annoyance, disrupting your daily routine and even affecting your sleep. If you’re wondering why your dishwasher is making such a racket, here are some common causes to consider:
1. Loose or Worn-Out Parts
Over time, the parts of your dishwasher can become loose or worn out, leading to increased noise. Check for loose components, such as the spray arms, racks, or door hinges. Tighten any loose screws or replace worn-out parts as needed.
2. Obstructed Water Flow
Restricted water flow can cause the dishwasher to work harder, resulting in louder noises. Ensure that the water supply hose is not kinked or blocked. Also, check the drain hose for any clogs or obstructions.
3. Faulty Motor
The motor is the heart of the dishwasher, and if it’s malfunctioning, it can generate excessive noise. Listen for any unusual humming, grinding, or squealing sounds coming from the motor compartment. If you suspect a motor issue, contact a qualified technician.
4. Hard Water Deposits
Hard water can leave behind mineral deposits on the dishwasher’s components, including the spray arms and heating element. These deposits can restrict water flow and cause the dishwasher to work louder. Use a commercial dishwasher cleaner or vinegar to remove hard water buildup.
5. Overloading or Improper Loading
Overloading the dishwasher or loading dishes improperly can imbalance the machine, leading to excessive noise. Make sure to load the dishwasher evenly and avoid overloading it. Also, ensure that dishes are placed securely in their designated racks.
6. Worn-Out or Damaged Impeller
The impeller is a component that circulates water in the dishwasher. If it’s worn out or damaged, it can create loud noises. Inspect the impeller for any signs of damage or wear and replace it if necessary.
7. Air in the Water Lines
Air in the water lines can cause the dishwasher to make banging or popping noises. Run the dishwasher with an empty load to purge any trapped air from the lines.
Alternative Solutions
If you’ve checked for the above causes and still can’t find the source of the noise, consider these alternative solutions:
- Use a dishwasher silencer pad: Place a sound-absorbing pad under the dishwasher to reduce vibrations.
- Install a noise-reducing hose: Replace your existing dishwasher hose with a noise-reducing hose that absorbs vibrations.
- Insulate the dishwasher: Install sound-dampening insulation around the dishwasher to block out noise.
