What Causes The LG Dishwasher nE Error Code?

LG dishwashers sense when there is a problem with the motor and displays a error code nE.

Have you run into an error message of some sort? To resolve it, try resetting the machine. To do that, follow the below steps: 

  • Power off the dishwasher and unplug it for 5-10 minutes. 
  • When you’re ready to use it again, plug the machine in and restart it. 

This should fix any simple system problems.

If this does not fix the problem, you should check your internal components. The nE error is usually caused by these factors.

Check Wiring

The LG Dishwasher Error Code nE indicates a faulty relay on the dishwasher control panel, which may have failed due to a broken or burnt wiring harness. When you’re encountering this error code, the first thing to do is to check the wiring harness between the Vario motor and the control panel.

This flaw can also be caused by a failure in the wiring harness next to the relay. If either of these problems is present, you need to reconnect the wire harness correctly using soldering iron in order to fix the problem.

To test the wiring, use a multimeter to confirm if the wires are sending out electrical current. If the multimeter reads 0V, then there is a break in the wire, and you should replace it with a new cable. Remember to turn off the dishwasher before doing work on it. If you don’t know how to work on big appliances, then it’s best to call an expert for help.

Faulty Vario Motor

LG dishwashers often come with a Vario motor, which allows the appliance to fit into narrow spaces. Vario motor repairs can be done by first checking the dishwasher’s wiring and ensuring that it is in working order.

If the wiring is okay, you should test the motor’s resistance using a multimeter. Ideally, it should have a resistance of approximately 4,000 ohms.

If your dishwasher’s Vario Motor has an infinite resistance value, it might be faulty and most likely needs to be replaced.

Defective Vario Motor Switch

After you have taken the resistance reading of your dishwasher’s Vario motor, you need to check the function of the motor switch. To do this, you will need: 

1. a multimeter with an ohm function 

2. wire strippers or scissors

To Troubleshoot LG Dishwasher nE Error Code, You will need to measure the resistance at the Vario position switch.

  • To test that the Vario switch plunger is functioning correctly, push in the dishwasher’s Vario switch plunger. 
  • You should also extend the switch plunger throughout this test to ensure it moves smoothly and performs to specifications.
  • When the trigger is pulled, the plunger should slide from the first position to the second. The multimeter should show that the resistance reading changes from infinite (greater than 100kΩ) to zero (less than 1Ω).

Faulty Control Panel

A faulty dishwasher control module can create all sorts of different errors. The best way to troubleshoot this issue is to check the wiring inside the control panel and ensure that it is correctly connected. A faulty control panel can result in LG Dishwasher nE Error Code.

You can use a multimeter to test the connection and make sure it is clean. If your dishwasher is still giving you issues, it may be a good idea to hire a local appliance repair service to replace the faulty control module.

Final Thought

LG dishwashers are engineered with safety in mind, but sometimes even the most resilient appliance will have issues. A common error code that pops up with LG dishwashers is LG Dishwasher nE Error Code.

By Checking the wiring harness, Vario Motor, and control switch can often solve the problem. If these components aren’t working correctly, appliance repair experts are on hand to help you out of a sticky situation.
