Common Causes of a Buzzing LG Dishwasher
1. Faulty Drain Pump:
The drain pump is responsible for removing water from the dishwasher during the rinse and drain cycles. A faulty drain pump can produce a loud buzzing noise due to a blocked impeller or worn-out bearings.
2. Clogged Drain Line:
A clogged drain line can prevent water from draining properly, causing the dishwasher to work harder and produce a buzzing sound. The clog can be caused by food debris, grease, or other objects trapped in the drain line.
3. Loose or Damaged Motor Mounts:
The dishwasher motor is mounted on rubber or plastic mounts to absorb vibrations and reduce noise. Loose or damaged mounts can cause the motor to vibrate excessively, resulting in a buzzing sound.
4. Worn-Out Water Inlet Valve:
The water inlet valve controls the flow of water into the dishwasher. A worn-out valve can create a buzzing sound as it struggles to open or close properly.
5. Faulty Control Board:
The control board is the brain of the dishwasher, controlling all its functions. A faulty control board can send incorrect signals to other components, causing the dishwasher to buzz abnormally.
6. Loose or Damaged Spray Arms:
The spray arms rotate to distribute water throughout the dishwasher. Loose or damaged spray arms can hit against the dishes or the walls of the dishwasher, producing a buzzing noise.
7. Overloaded Dishwasher:
Overloading the dishwasher can put excessive strain on the motor and other components, leading to a buzzing sound. Make sure to only load the dishwasher with the recommended number of dishes.
Troubleshooting and Repair
1. Check the Drain Pump:
Inspect the drain pump for any blockages or debris. Remove any obstructions and ensure that the impeller is rotating freely. If the bearings are worn out, the pump may need to be replaced.
2. Clean the Drain Line:
Disconnect the drain line from the dishwasher and inspect it for clogs. Use a drain snake or a wet/dry vacuum to remove any obstructions.
3. Tighten Motor Mounts:
Check the motor mounts for any loose screws or bolts. Tighten them securely to reduce vibrations and eliminate buzzing.
4. Replace the Water Inlet Valve:
If the water inlet valve is faulty, it will need to be replaced. Disconnect the power supply and water supply before attempting this repair.
5. Reset the Control Board:
Sometimes, a faulty control board can be reset by unplugging the dishwasher for 30 minutes and then plugging it back in. If this does not resolve the issue, the control board may need to be replaced.
6. Inspect Spray Arms:
Ensure that the spray arms are properly attached and not damaged. Replace any damaged spray arms and tighten any loose connections.
7. Avoid Overloading:
Follow the manufacturer’s recommendations for the maximum number of dishes that can be loaded into the dishwasher. Overloading can put unnecessary strain on the appliance and lead to buzzing.
Prevention Tips
1. Regularly Clean the Drain:
To prevent clogs, regularly clean the drain filter and remove any food debris or other objects that may accumulate over time.
2. Use a Dishwasher Cleaner:
Run a dishwasher cleaner monthly to remove mineral buildup and keep the appliance running efficiently.
3. Avoid Overloading:
As mentioned earlier, avoid overloading the dishwasher to prevent excessive strain on the components.
4. Inspect the Dishwasher Periodically:
Check the dishwasher periodically for any loose parts or damage. Address any issues promptly to prevent them from becoming more severe.
5. Call a Qualified Technician:
If you are unable to resolve the buzzing issue on your own, do not hesitate to call a qualified appliance technician for assistance.
