Fixed -LG Dishwasher NE Error Code

One of the most recognizable dishwasher brands on the market is an LG Dishwasher. It’s one of the most common appliances used and advertised in many countries.

But, just like any brand, an LG dishwasher can also experience problems. Thankfully, there is usually an error code to tell you exactly what the problem is. However, this can still be quite challenging if you are not familiar with technical terms. But if you read and familiarize yourself with the parts and terms of your LG dishwasher, it can make it a little easier.

A manual comes with every dishwasher you buy. Every error code displayed on the appliance references a specific problem. A common error code experienced by an LG dishwasher is the NE error code.

An NE error code would normally mean a problem with your dishwasher’s vario motor or diverter motor. The vario motor/diverter motor controls the dishwasher’s spray arms. Less commonly, the NE error code could be more than a vario motor problem, but we cover that down below too.

So how do we fix an LG dishwasher that experiences an NE error? Here are a few tips to remember:

Do Some Basic Troubleshooting

One of the first things you can do to fix an LG dishwasher is some basic troubleshooting. Sometimes, all you need to do is reset your dishwasher.

You can reset it by turning off the dishwasher and waiting around 10 to 15 seconds. After, you can open and restart the dishwasher. Don’t forget to run a small cycle to check that it’s working again. Also check that the racks are positioned properly inside the dishwasher. Put the pots, pans, dishes, and glasses inside properly and close the door securely. Ensure that you are using the right dishwashing detergent for your specific dishwasher model. Sometimes, an incorrect detergent or amount can cause a problem.

If you reset it and the dishwasher error code NE still appears, then this means you’ll need to do some handy work by dismantling your dishwasher or calling your handyman to fix the problem.

Check The Dishwasher’s Wiring

A broken or burnt wire could be the culprit causing the error code. For example, a burnt wire could send a wrong signal to the dishwasher, causing the LG dishwasher error code.

To check the wiring, you’ll need to look at the wiring harness found between the vario motor and control panel. Double-check its alignment and for broken or burnt wire. If you find a broken or burnt wire, replace the cable immediately with a new one.

To make sure that they are functioning properly, you can conduct a test by using a multimeter. While doing this, you may also want to check other things, like the water valve and hose, while the appliance panels are already off. After replacing any faulty wires, run another test to see if the error code goes away.

Check the Vario Motor

If you have no wire issues, you might want to check your vario motor/diverter motor. First, you need to unscrew the vario motor to check for any damage. You can check for damage to a diverter motor/vario motor by testing its resistance. The resistance should be around 4000 Ω.

If you get more than 4000 Ω, it means you’ll need to replace it.

  1. Before removing the motor, make sure to turn off the water supply and the power.

  2. Carefully remove all the parts, including the screws, to release the lower access panel.

  3. Disconnect the water supply line from the inlet valve.

  4. Unscrew and remove the junction box cover and disconnect the drain hose.

  5. Remove all parts and set them aside until you reach the motor and replace it with a new one.

  6. Once you replace the vario motor/diverter motor with the new one, put everything back together. Make sure to secure it tightly.

  7. Restore power and water to the dishwasher and check for an NE error by running a small cycle.

Broken Control Panel

Sometimes the error code might be due to a control panel problem. A broken control panel might send the wrong error signal. The best thing to check is the wiring inside the control board to see if everything is still in place. Additionally, you can check the settings and switch to see if they are working too. One way to check the connection and find out if it’s working is to use a multimeter. If the mainboard has a problem and the signal is failing, replace it with a new one. If you are unsure about this repair, it’s the perfect time to call a technician or appliance specialist.

Call a Trusted Technician

If you did basic troubleshooting and tried repairing it yourself but still have problems, it might be time to call an expert. A technician or handyman can repair the appliance and see the tiniest of issues, from a circuit breaker to a water supply line. Sometimes, it’s best to leave the repairs to someone with professional knowledge and specialized skills. It’s best to avoid touching or attempting to repair something if not equipped with the right knowledge or tools; you might end up with not just a problematic appliance but additional repairs and expenses as a result.

Summary

The LG dishwasher has functions that a user must be familiar with. When encountering an NE error code, the first thing you can do is basic troubleshooting by switching the appliance off and back on again, checking for a repeat error code. If you know how to do basic repairs, you can try the things listed above. If you’re not comfortable with it, or the problem persists after, it’s best to call a local technician or handyman.
