LG Dishwasher Making Noise? This Could Be Why!

Share This Tip

LG dishwashers are known for their quiet operation and efficient cleaning power. However, if you are experiencing excessive noise coming from your LG dishwasher, it can be a frustrating experience. This noise can be caused by a number of factors, from a blocked spray arm to worn-out parts. So why is your LG dishwasher making noise?

Why Is My LG Dishwasher Making Noise?

An LG dishwasher can make several different noises and in order to properly diagnose the cause of the noise, it is important to consider the type of noise being made and assess if there are any visible signs of wear or damage. Regular maintenance, avoiding overloading, and cleaning the dishwasher regularly can help prevent some of these issues.

Common LG Dishwasher Noises:

  • Whining or Whistling
  • Buzzing
  • Banging
  • Grinding

LG Dishwasher Making Whining Noise

If you hear a whining or whistling noise coming from your LG dishwasher, it could indicate that water is entering the unit which is a normal occurrence. However, if the noise is loud and high-pitched, it may indicate that the water volume is too high. In this case, you may need to adjust the tap to reduce the amount of water entering the dishwasher and resolve the issue.

Buzzing Noises

The most common cause of buzzing noises in an LG dishwasher is incorrect dish loading. If dishes are stacked too close together, they can vibrate against each other during a wash cycle, creating a buzzing sound. Other potential causes of buzzing include a clogged spray arm, a damaged wash motor, or a foreign object inside the dishwasher. To resolve the issue, it’s recommended to load the dishes and clear any blockages properly, and if the buzzing persists, to seek assistance from an LG repair service provider.

Banging Noises

Banging noises in an LG dishwasher are often caused by the spray arm running into dishes blocking its path. When the spray arm can’t spin freely, it creates a banging sound during the wash cycle. To fix this, check that the dishes are not blocking the spray arm before starting a cycle. You can do this by attempting to spin the spray arm manually. If it can’t rotate fully, adjust the position of the dishes until it can.

Dishwasher Making Loud Grinding Noise

If you hear grinding noises from your LG dishwasher during a wash cycle, it may indicate a problem with the circulation pump motor. The motor, responsible for circulating water throughout the dishwasher, has several parts, such as an impeller and bearings, that can wear out over time.

When these parts fail, it can cause the motor to make a grinding noise. If you experience this issue, it’s important to have the circulation pump motor inspected and, if necessary, replaced by a professional.

Tips to Prevent LG Dishwasher Making Noises

To prevent your LG dishwasher from making noise, there are several maintenance steps you can take. First, regularly clean the dishwasher, including the interior and exterior. This will prevent the buildup of debris, grime, and food particles that can cause blockages and produce noise.

Secondly, make sure to check and clean the filter regularly. A clogged filter can restrict the water flow and cause the dishwasher to work harder, leading to noise. These simple steps can help keep your LG dishwasher running quietly and efficiently.
