The Reasons Your Dishwasher Is Making Loud Noises

There are a couple of answers to why your dishwasher is making loud noises, as you will soon realize. However, in addition to helping you understand the reason for the sound, we will show you how to repair your dishwasher.

A Defective Drain Pump

If the drain pump of your dishwasher is bad, that may be the reason it is making loud noises. What the drain pump does is to pressurize the spray arms and also remove water from the dishwasher. This pump is a vital part of the cleaning process. At the beginning of the wash cycle, it removes water from the machine and does the same thing after the cycle. 

If debris like glass shards or other wayward objects get in the pump chamber, they can cause quite a commotion when they hit the pump impeller. So, if your dishwasher is making funny noises at the beginning of the wash cycle, the drain pump may be the culprit.

Wash Arm Bearing Ring and Spray Arm Seal

These parts may be what causes loud noises in your dishwasher. The wash arm bearing the ring and spray arm seal are plastic rings that support the rotating arm of the washer and the spray arm, respectively. If either part wears out or becomes loose, the wash arm and spray may not function properly. This can lead to loud noises when you attempt to operate your dishwasher.

A Faulty Recirculation Pump

If the above two reasons are not why your dishwasher is making loud noises, then it may be a problem with your circulation pump. The function of the recirculation pump is to send water gathered at the bottom of the dishwasher back through the spray arms during the wash cycle. 

If broken shards of porcelain or related debris get in the recirculation pump units, it can become very noisy. This is because as the pump tries to expel water, whatever object is in it will bang around in the pump chamber, creating unsettling noises.

A Defective Water Inlet Valve

Problems with the water inlet valve can result in loud noises in your appliance. However, the good news is that it is particularly easy to identify if your water inlet valve is the problem. Your dishwasher may have a faulty water inlet valve if it makes loud noises when water is running. If the water inlet valve is the culprit, as soon as you turn the water off, the sound will seize.

Quick Tips to Help You Fix Dishwasher

Now that we have told you ways to identify why your dishwasher is making loud noises, let’s explore how you can remedy the problem. Here are a few tips for repairing a dishwasher with loud noises. 

Note that before you attempt any troubleshooting on your dishwasher, you must unplug the unit.

  • If your drain pump is the problem, you need to check to make sure there is no debris stuck in the impeller pipes. If there isn’t, then your drain pump itself may be faulty and need replacement. To confirm, take it out and test it with a multimeter.
  • You may also need to inspect your wash arm bearing ring and spray arm seal for signs of wear and tear. You will find these on the wash and spray arms. Also, you may need to remove them to inspect them for damage thoroughly. If you notice signs of wear, you should replace them.
  • Also, to rectify noises that your recirculation pump causes, you will need to clean out debris in the pump chamber. After this, if the pump still rattles, you may need to replace the unit.
  • More often than not, if your water inlet pipe is the problem, a simple replacement will solve this problem.
