How To Fix an NE Error Code on an LG Dishwasher

Dishwasher 14

When you see an NE error code on your LG dishwasher, it’s a clear sign that there’s a problem with the Vario motor or diverter motor. This motor is responsible for controlling the dishwasher’s spray arms, directing the water pressure to clean your dishes effectively. But don’t worry, this comprehensive guide will walk you through the steps to troubleshoot and fix this issue.


To fix an NE error code on an LG dishwasher, first power cycle the dishwasher and inspect the wiring. If the error persists, check the Vario motor’s resistance using a multimeter. If the motor is faulty, you’ll need to replace it. If the wiring is broken, repair it. If neither of these steps work, the issue may lie with the control panel, which should be replaced by a professional. Always remember to take safety precautions when troubleshooting your dishwasher.

Understanding The NE Error Code

An NE error code usually indicates a fault within the dishwasher’s Vario motor. However, other factors can also contribute to this error, such as a temporary system failure, broken wiring, or a faulty relay on the control panel. Regular maintenance and checking for potential issues can help prevent the NE error code from appearing.

Initial Steps To Take

When you first encounter the NE error code, follow these initial steps:

  1. Power Cycle the Dishwasher: Simply turn off the dishwasher, wait for about 15 seconds, and then turn it back on. Power cycling can often clear temporary system glitches that might be causing the error code.
  2. Inspect the Wiring: Carefully check the wiring harness connected to the motor and diverter microswitch. Ensure all connectors are firmly inserted and there are no breaks that could be interfering with signal transmission.
  3. Check the Vario Motor: If the wiring is fine, disconnect the wires and measure the resistance of the motor using a multimeter. The reading should ideally be around 4,000 Ω. If the resistance is infinite, it means the motor may need to be replaced.

Diagnosing The Specific Cause

If the NE error code persists after the initial troubleshooting, you may need to diagnose the specific cause. Inspect other aspects that could indirectly influence the NE error occurrence, such as the drain hose, water temperature sensor, water pressure, micro switch, dishwasher tube, water level, filter, and the function of the drain pump. If you’re unsure about any of these elements, it’s recommended to call a professional technician to inspect your dishwasher.

Fixing The NE Error Code Based On The Cause

Once you’ve diagnosed the specific cause, you can take the appropriate steps to fix the issue:

  1. Hardware Malfunction: If a system failure is causing the error, a simple power cycle should fix the issue. However, if the problem persists, you may need to call in a professional.
  2. Broken Wiring: If the wiring harness going to the motor and diverter microswitch is loose or broken, you’ll need to tighten the connections or repair the wires.
  3. Vario Motor Failure: If the motor is faulty, you’ll need to replace it. Make sure to purchase a motor that’s compatible with your specific LG dishwasher model.
  4. Faulty Control Panel: If the control panel is malfunctioning, you’ll likely need to replace it. This is a more complex process that should be done by a professional.

Safety Precautions To Take

Before attempting to fix the NE error code yourself, make sure to take the following safety precautions:

  1. Disconnect the power and turn off the water supply.
  2. Wear protective gear, such as gloves and safety goggles.
  3. Use the correct tools for the job.
  4. Follow manufacturer guidelines.
  5. If you’re not comfortable with any aspect of the repair process, call a professional.

Preventing The NE Error Code

To avoid encountering the NE error code in the future, consider the following preventive measures:

  1. Regularly clean the dishwasher filter.
  2. Tighten any loose wiring connections.
  3. Maintain proper water pressure.
  4. Inspect the Vario motor regularly for signs of wear or damage.

Remember, regular maintenance can help prevent issues like the NE error code and keep your dishwasher running smoothly. However, if the code persists even after you’ve followed the steps in this guide, it’s best to call a professional technician.

While fixing an NE error code on an LG dishwasher can seem daunting, it’s often a simple process that can be done with a little patience and know-how. So next time you see that dreaded NE error code, don’t panic. Just follow this guide, and your dishwasher will be back up and running in no time.

Frequently Asked Questions

What is a Vario motor in an LG dishwasher?

The Vario motor in an LG dishwasher is a crucial component that controls the movement of the dishwasher’s spray arms. It directs the water pressure to different areas inside the dishwasher, ensuring your dishes are cleaned effectively.

How can I check if the control panel is faulty?

Checking the control panel for faults requires a multimeter and a basic understanding of electrical circuits. You’ll need to disconnect the power, access the control panel, and measure the resistance across various connections. However, this can be a complex process and is best left to professionals if you’re unsure.

Where can I purchase a replacement Vario motor for my LG dishwasher?

Replacement Vario motors for LG dishwashers can be purchased from various online retailers, home appliance stores, or directly from LG’s official website. Always ensure the motor is compatible with your specific dishwasher model before purchasing.

How often should I clean the dishwasher filter to prevent the NE error code?

It’s recommended to clean your dishwasher filter once a month to ensure optimal performance and prevent issues like the NE error code. However, this can vary based on usage. If you use your dishwasher daily, consider cleaning the filter more frequently.

What does it mean if the resistance of the Vario motor is infinite?

If the resistance of the Vario motor is infinite, it means there’s no continuity, or the current can’t pass through the motor. This typically indicates a fault or break in the motor, and it will likely need to be replaced.
