How to troubleshoot & fix the NE error on an LG dishwasher


Steven E / Friday May 24, 2024


One common error code that might show up on your LG dishwasher is “NE”, which typically means there’s an issue with the diverter motor (also called a Vario motor). The diverter motor controls the spray intensity and direction during the dishwashing cycle.

Let’s unpack this error code so you can find out what’s going wrong and how to fix it.

What causes the NE error code?

The NE error on LG dishwashers is primarily caused by issues with the diverter motor. Other factors that can indirectly cause this error code include:

  • Faulty or loose wiring that causes an electrical disconnect between the motor and the dishwasher’s control board
  • A malfunctioning electronic control board

How to troubleshoot the NE error

Troubleshoot and resolve the NE error code on your LG dishwasher by following these steps.

Step 1: Power cycle the dishwasher

  1. Turn off the dishwasher and unplug it from the power outlet.
  2. Let the dishwasher rest unplugged for at least 2-3 minutes so the dishwasher’s electronic control board can reset.
  3. Plug the dishwasher back in and turn it on.

If the error code still shows up, move on to the next step.

Step 2: Check the wiring

  1. Unplug the dishwasher from the outlet.
  2. Remove the bottom kick plate or toe panel to access the dishwasher’s internal wiring.
  3. Look over the wiring and pay special attention to the connections of the diverter motor. Check for any frays, burn spots or loose connections. Tighten any loose connections you find. If you find any damage, replace the wiring.

If you suspect a specific wire may be causing the issue, you can test it individually. Disconnect both ends of the wire and set your multimeter to the continuity mode. Then place one meter lead on one end of the wire and the other meter lead on the opposite end. If the meter shows continuity (closed circuit), then the wire is good. If there’s no continuity, it means there’s a break in the wire that needs to be repaired or the wiring harness will need to be replaced.

If the wiring looks good, move on to the next step.

Step 3: Check the diverter motor

  1. Disconnect the drain and inlet hoses and remove the dishwasher from under the countertop.
  2. Remove the base to access the motor, which is typically at the bottom of the dishwasher.
  3. Disconnect the wires attached to the motor and remove it from its slot.
  4. Set the multimeter to the resistance mode.
  5. Use the meter probes to check for resistance between the motor terminals.
  6. Check the meter, which should read around 4,000 Ohms. If the reading is more than 200 Ohms different than this, then the motor needs to be replaced.

If the motor and all other parts are good, replace the control board as a last resort.
