You are not alone, and the good news is that this error is very common and quite easy to fix. After going through some instructions, you can diagnose the problem and get your dishwasher up and running in no time.
In this post, we explain what the NE error code on an LG dishwasher means, what causes it, and how you can troubleshoot it step by step. By the end of this, you will have every confidence to handle the problem yourself or know whether to call the professionals.
What Does the NE Error Code Mean on an LG Dishwasher?
The NE error code on LG dishwashers refers to a fault in the motor responsible for the movement of the dishwasher spray arm. This is often referred to as the “vario motor,” which provides variable speed and direction to the spray arm while in a wash cycle. When this motor fails, the system cannot spray water correctly to wash your dishes.

Common causes that raise this error code include:
- Vario motor failure or jamming
- The problem at the wiring or at the connection
- Technical Error at the control board of a dishwasher
From all of above possibilities, we will be taking a few steps necessary to troubleshoot it.
NE Error Code Troubleshooting
Following are some steps which have to be done in order to troubleshoot it. Do follow all of these below steps once you are certain that your dishwasher is unplugged and water supply has been turned off:
Step 1: Restart Your Dishwasher
First try a quick restart, as this may be due to a momentary glitch.
- Switch the dishwasher off and pull it away from power.
- Wait approximately 10 minutes to let the system cool down.
- Plug it back in, turn on the appliance, and check to see if the error has cleared.
If this code persists, proceed with the following steps.
Step 2: Check Spray Arm
The spray arm might be obstructing the smooth flow or clogged itself, therefore hindering the operation of the vario motor.
- Open your dishwasher and remove the lower and/or top spray arms from their holder; they are usually twisted off easily
- Scrape off food, grease, or any other substances that may impede the flow
- Wash the spray arms thoroughly under running water and return them.
- Run a short cycle to see if this clears the error code.

Step 3: Vario Motor Check
If the spray arm is clean but the error persists, it is time to take a closer look at the vario motor.
- Find the Vario Motor: Refer to your user manual; it is usually located underneath the bottom rack with the spray arms.
- Look for visible damage, debris, or obstructions.
- If you’re comfortable, use a multimeter to check if the motor is receiving the correct electrical current. If it isn’t, it might need replacing.
Keep in mind that this step may require a bit of technical skill. If you’re unsure, don’t hesitate to call a professional to inspect it for you.
Step 4: Inspect the Wiring Connections
A loose or damaged connection could be causing the NE error code.
- Check all wiring to the vario motor for any visible damage or disconnections.
- Secure any loose connections and check for frayed or exposed wires.
- When you find that a wire has been damaged, replacing it will be better, instead of letting the problem continue.
Step 5: Check the Control Board
If the above steps do not work, the issue might be in the control board of the dishwasher.
- The motor receives signals from the control board; it can be faulty and send the wrong signals.
- Always check the control board for signs of burn, damage, or loose wiring.
- Remember that it is among the most complicated parts to fix and replace; if you feel this is the issue, better call a pro.

Bonus Tip: Maintenance Tips
Make regular maintenance your habit for keeping this error code away. Some include:
- clean your spray arms, filters, and the interior of the dishwasher once in a month;
- Running dishwasher cleaner to clear all grease accumulation through a cycle
- Every use will need a routine cleaning after taking out food chunks, that’ll ensure a problem-free performance by its elements and gives the device the longest possible life.
When to call on Professional?
If you’ve tried all the troubleshooting steps and the error still won’t go away, or if you’re uncomfortable performing some of the steps, it might be time to call in a professional. An experienced technician can quickly identify and resolve more complex issues, ensuring your dishwasher gets back to optimal performance.
Also, if the dishwasher is within the warranty period, contacting the customer care team at LG can be a great first step; they can offer guidance and may cover the costs of repair.
Conclusion
The NE error code on an LG dishwasher should not give you any headache or ruin your day. A little patience will often pay off with the above-mentioned steps, and you’ll be back to clean dishes in no time. And remember, with regular maintenance, such glitches could be kept away.
