Are you getting the LG Dishwasher Error Code nE? Well, You are at the right place as we have given a complete solution on how to fix this error. So what does nE error means in LG dishwasher? It indicates that there is a problem with the Vario motor. The main function of the Vario motor is to control the water spray arm. So if it does not work properly, the dishwasher can’t spray water properly to wash the dishes.
We also recommend checking the micro-switch. The switch’s main job is to send the signal to the control panel and tells it about the dishwasher motor position. When this happens, the nE error will happen. You need to replace the defective micro-switch so that it again send the correct signal to the control board.
How To Fix LG Dishwasher Error Code nE
As we have already stated before, the dishwasher spray arm is controlled by the Vario motor, which is a type of electric motor. This electric motor is run with the help of Micro Switch. They both combine to supply water every 90 seconds to the spray nozzles so that the dishes can be clean efficiently without using much water. The water will go through all the nozzles from lower to middle and then to the upper nozzle and vice versa.
As always, first, you need to reset the error by doing the basic troubleshooting and diagnosis. Many times if it’s a simple system failure, then it can be easily resolved without checking the internal parts. Let’s see how to do it.
- Switch Off the Dishwasher.
- Wait for 10-15 minutes.
- Restart the LG dishwasher again.
In most cases, it should reset the nE error. If you are still getting the issue, then you have to check the internal parts.
If the wiring is broken or burnt, then the control module will not receive correct signals, which can result in the LG Dishwasher Error Code nE. You need to check the wiring harness between the Vario motor and the control panel. Ensure that it is incorrect alignment, and there are no broken or burnt wires.
Use a multimeter to test the signal. If you find the faulty wire, then please replace the cable with a new one. One thing I want to say that before doing any step, please make sure that the dishwasher is OFF. Also, if you don’t have any experience of handling big appliances, then its always better to take the help of an expert.
Check Vario Motor/Diverter Motor
If after careful inspection, You are sure that wiring harness is not causing the error, then you need to check the motor. The way you can do it is to check the resistance of the motor and ensure that it is displaying the correct value. After long use or if the motor is faulty, then it will not show the correct value. Also, many times the seal can wear out by water.
The resistance for most dishwashers should be around 4000 Ω. If you are getting way higher or infinite resistance, then it is best to replace the Vario motor with a new one. Let’s see how to do it.
- Turn off the power to your dishwasher.
- Shut off the water supply valve.
- Remove the screws to release the lower access panel.
- Disconnect the water supply line from the inlet valve.
- Remove the screw to release the junction box cover and note the location of the wires.
- Disconnect the drain hose from the sink drain or garbage disposer.
- Pull the dishwasher away from the cabinet, open the door, and remove both the upper and lower dish racks.
- Now disconnect the diverter motor wire harness.
- Remove the mounting screws.
- Securing the motor and lift the old motor out.
- Install the new Vario Motor.
- Put all parts back again.
Restart the dishwasher again, and we hope that now you will not get the error.
Broken Diverter Switch
After checking the resistance of the diverter motor, and found that it is in good condition, then you need to check the Diverter Switch. Usually, when the piston is pushed up and down, the resistance can be infinite and with extended one having the resistance of 0 Ω. In either case, if you see the resistance is the same, then the Diverter/Micro Switch is not able to get the correct position of the diverter motor. Hence control module will not receiver proper signal that will result in LG Dishwasher Error Code nE.
We recommend replacing the faulty Micro Switch with a new one.
Faulty Control Panel
Many times, the control module is faulty and will display incorrect errors. Check the wiring inside the control panel and ensure that there are correct. You can use a multimeter to test the connection. We also suggest hiring a professional handyman that can help you in doing these steps. Also, it is better to replace the faulty control board rather than repairing it as it may cost more.
We hope that we can solve your problem. We have also given a solution for Error Code LE on our website. So do check out that one as well.
