Why Is Your LG Dishwasher Making Loud Noise?

Say goodbye to that noise that’s been driving you nuts for days – let’s figure out what’s causing your LG dishwasher making loud noise and how to fix it with these tips!

1. Dishwasher Circulation Pump is Making Noise

The water pump in your dishwasher helps move the water around during a cycle. If this part becomes clogged or damaged, it can cause your dishwasher making noise when water circulates. The noise will usually happen during the wash or rinse cycle and will sound like a loud whirring or clicking sound.

To fix this issue, you should check the pump filter and unclog it if necessary. You can also replace the water pump with a new one if needed.

2. Spray Arm Can’t Spin Freely

The spray arm cleans and sprays dishes during a cycle. If it can’t spin freely, you may hear a loud noise while the dishwasher is running when it bangs into dishes.

To fix this issue, check the spray arm and make sure that it has enough room to spin. If it is blocked in any way, you should move the dishes around to give them some space.

3. Dishwasher Drain Impeller Issue

The dishwasher drain impeller is responsible for draining the water from your dishwasher. If it becomes clogged or damaged, you will hear a loud buzzing sound which will eventually turn into a squealing issue as the problem progresses. You will also notice that your dishwasher will have issues draining and it could even cause dishwasher leaking issues, or leave you with a dishwasher that smells bad.

To fix this issue, you should check the impeller in the drain and make sure there are no issues. If necessary, you can replace the impeller with a new one.

4. Dishes Banging Together in Dishwasher

If your dishes are banging and clanging together inside the dishwasher, this can cause a lot of noise. This happens when there are too many dishes in the dishwasher or when they are not arranged properly.

To fix this issue, you should rearrange the dishes so they do not hit each other during a cycle. You may also need to adjust the height of the tray inside the dishwasher or add some space between the dishes.

To fix this issue, you should check the inlet valve and make sure it is not clogged or damaged. If necessary, you can replace the inlet valve with a new one.
