Common Causes
Understanding the common causes behind an LG dishwasher arm not spinning can help in diagnosing and fixing the problem. This section will explore two primary reasons: a blocked spray arm and a pump malfunction.
Blocked Spray Arm
A blocked spray arm is a frequent issue in dishwashers. Food particles or debris can clog the small holes in the spray arm. This prevents water from flowing freely. As a result, the arm cannot spin effectively. Regular cleaning can help avoid this problem.
Pump Malfunction
The pump plays a crucial role in circulating water throughout the dishwasher. If the pump fails, water will not reach the spray arm. This can cause the arm to stop spinning. A faulty pump often requires professional repair or replacement.
Basic Troubleshooting
LG dishwasher arm not spinning? Check for blockages, clean the spray arm, and ensure proper water pressure. Simple fixes can often solve the issue.

First, open the dishwasher door. Remove the bottom rack to access the spray arm. Check if the spray arm is attached properly. It should spin freely. If it seems loose or wobbly, adjust or tighten it.

Is your LG dishwasher arm not spinning? Don’t worry, you’re not alone. Many homeowners face this issue, but with the right approach, you can get your dishwasher back to peak performance. Let’s dive into some advanced diagnostics to help you troubleshoot and resolve this problem.
Motor Issues
The motor in your LG dishwasher is crucial for the spinning action of the arm. If the motor is faulty, the arm won’t spin correctly. Here are some signs to look out for:
- Noise: A malfunctioning motor might produce unusual sounds.
- No Movement: If the arm is completely stationary, the motor could be to blame.
- Overheating: A hot motor indicates it’s working too hard or malfunctioning.
To diagnose motor issues, you can perform the following checks:
- Unplug the dishwasher from the power supply to avoid any electrical hazards.
- Locate the motor by referring to your dishwasher’s manual.
- Check for any visible damage or blockages.
- Use a multimeter to test the motor’s continuity. If it fails, you’ll need to replace the motor.
Electronic Control Problems
The electronic control system of your LG dishwasher manages various functions, including the spinning of the arm. A glitch in the control board can halt the spinning process. Here’s what you can do:
- Reset the Dishwasher: Sometimes, a simple reset can fix the issue. Unplug the dishwasher, wait a minute, and then plug it back in.
- Check for Error Codes: Modern LG dishwashers display error codes. Refer to your manual to decode them.
- Inspect the Control Board: Look for any burnt or damaged components on the control board.
If you suspect the control board is faulty, it might be time to call a professional. However, if you’re comfortable with electronics, you could try replacing the board yourself. Always ensure the power is off before attempting any repairs.
In conclusion, while an LG dishwasher arm not spinning can be frustrating, understanding motor issues and electronic control problems can help you pinpoint the issue. With a bit of patience and these advanced diagnostics, you’ll have your dishwasher running smoothly in no time.
Replacement Parts
When your LG dishwasher’s arm stops spinning, it disrupts your daily routine. The issue often arises from malfunctioning parts. Replacing these parts can solve the problem and restore your dishwasher’s efficiency. Let’s explore some essential replacement parts.
Spray Arm Replacement
The spray arm is crucial for cleaning dishes. If it doesn’t spin, it won’t distribute water evenly. Check for clogs or damage. If needed, replace the spray arm. Remove the old spray arm and install a new one. This simple fix can enhance cleaning performance.
Pump And Motor Replacement
The pump and motor power the spray arm. If they malfunction, the arm won’t spin. First, inspect the pump and motor for any signs of damage. If they are faulty, replace them. Disconnect the power and water supply before starting. Remove the defective parts and install new ones. This ensures your dishwasher runs smoothly.
Diy Fixes
Having trouble with your LG dishwasher arm not spinning? Don’t worry. You can try some DIY fixes before calling a technician. These simple steps can help get your dishwasher back to its optimal performance.
Cleaning The Spray Arm
The spray arm can get clogged with food particles. Remove the spray arm from the dishwasher. Use a toothpick or small brush to clear any debris from the holes. Rinse the spray arm under running water. Ensure all holes are clear before reattaching it to the dishwasher.
Unclogging Filters
Clogged filters can also stop the spray arm from spinning. Locate the filters at the bottom of the dishwasher. Remove them and rinse under running water. Use a brush to remove stubborn debris. Once clean, place the filters back in their position. This should help improve water flow and spray arm function.

When To Call A Professional
When your LG dishwasher arm stops spinning, it can be frustrating. Sometimes, simple troubleshooting can solve the problem. But other times, a professional is needed. Knowing when to call a professional can save time and money.
Identifying Complex Issues
Some issues are hard to diagnose without expert help. If you notice leaks, strange noises, or the dishwasher not draining, these could be signs of bigger problems. A professional can identify and fix these issues quickly.
Electrical problems are another red flag. If your dishwasher’s control panel is not working or you smell burning, call a professional. These issues require specialized knowledge and tools.
Cost Considerations
Think about the cost of parts and labor. Some repairs are simple and inexpensive. But if the motor or control board needs replacing, costs can add up. A professional can give an accurate estimate before starting the work.
Also, consider the age of your dishwasher. If it is older, repairs might not be worth the cost. A professional can advise if it’s better to repair or replace.
