If your dishwasher has been making a loud noise lately, you’re not alone. This is a surprisingly common problem that can be caused by a variety of factors. In most cases, it’s nothing to worry about – it’s just a minor problem that can be fixed easily. However, in some cases, the problem may be more serious. Here are seven reasons why your dishwasher is making a loud noise and what you can do about it.

What to Do If Your Dishwasher Is Making a Loud Noise

Is that noise coming from your dishwasher making you crazy? Don’t panic – there are a few steps you can take to try and fix when your dishwasher is making a loud noise.

1. Spray Arm Hitting Dishes

If your dishes are too close together in the dishwasher, then it’s possible that the spray arm is hitting them as it rotates. This will cause a loud thumping noise from a dishwasher, so you’ll need to rearrange your dishes to ensure that they’re not obstructing the arm.

2. Overloaded Dishwasher

If your dishwasher is overloaded with dishes or cutlery, then it could be struggling to work efficiently. This puts extra strain on the motor and can cause a loud noise as it works. It also will result in dishes banging together, which could also cause a loud noise. To fix this, simply adjust the number of dishes and cutlery you put in each cycle. If you’re dealing with issues like dishes not drying this could also be the cause.

3. Broken Dishwasher Motor

If the noise coming from your dishwasher is particularly loud and continuous, then it could be due to a broken motor. A damaged motor will make grinding and buzzing noises as it struggles to turn on. This issue can also result in your dishwasher not starting. If this is the case, then you’ll need to have your dishwasher serviced or replaced entirely. If your dishwasher is a bit older, then it’s possible that the motor bearings have become worn out. This will cause loud grinding noises as the motor struggles to turn on. To fix this problem, you’ll need to have the bearings replaced by an experienced technician.

4. Blockage in the Drain Hose

Sometimes, a blockage in the drain hose can cause your dishwasher to make a loud noise as it struggles to pump out water. If you find your dishwasher making noise when draining this is likely the issue. To check for this problem, you’ll need to examine the hose for any clogs or debris. If there is a blockage, you can remove it and the noise should stop.

5. Dishwasher Filter Clogged

Clogged filters can be the source of many dishwasher problems, including loud noises. Remove the filter(s) from your dishwasher and clean them thoroughly with warm, soapy water. If this doesn’t fix the issue, try replacing the filter.

6. Loose Parts

If you’ve recently moved your dishwasher or had to take it apart for some reason, then it’s possible that some of its parts may have become loose over time. This could be the cause of the loud noise, so you’ll need to check that all the screws and parts are properly secured and tightened.

7. Worn Out Pump

If the noise coming from your dishwasher is more of a humming sound that occurs when it’s filling with water, and you find your dishwasher making loud noise when starting, then it could be due to a worn-out or damaged pump. This is an issue that will require professional help, as you’ll need to have the pump replaced by an experienced technician.
