In modern appliances, error codes are designed to help us understand the problems our devices might be facing. However, they often come with a lot of confusion, and one such common error code is the “nE” error code on LG dishwashers. This error code refers to an issue with the dishwasher’s “Vario” motor.
While the LG dishwasher nE error code primarily indicates an issue with the Vario motor, other aspects such as the drain hose, water temperature sensor, poor water pressure, micro switch, dishwasher tube, water level, filter, and the function of the drain pump should not be overlooked.
They all work together in the dishwasher’s optimal operation and could indirectly influence the nE error occurrence if not functioning correctly.
Causes of LG Dishwasher Error Code nE
These are the primary causes of the nE error on LG Dishwashers:
1. Hardware Malfunction
The “nE” error generally means that your LG dishwasher’s “Vario” motor isn’t working right. This motor changes the spray arms’ intensity and direction during the dishwashing cycle. You might see the nE Vario Motor error code displayed if there is a hardware malfunction.
2. Faulty Wiring
Faulty or loose wiring might cause an electrical disconnect between the Vario motor and the dishwasher’s control board, causing the nE error code to appear.
3. Control Panel Issue
Sometimes, the problem could be due to a faulty control panel or a malfunctioning electronic control board. Make sure to check the power button too.
How to Fix LG Dishwasher Error Code nE?
1. Power Cycling
Power cycling is a simple yet effective troubleshooting method that can fix various electronic and appliance issues, including the nE error code on your LG dishwasher. Here’s a detailed step-by-step guide on how to power your dishwasher:
- Turn Off the Dishwasher: Start by ensuring the dishwasher is not in use. Then, turn off the dishwasher using the power button on the control panel and turn off the water supply lines.
- Unplug the Dishwasher: For a proper power cycle, you also need to disconnect the dishwasher from the power and water supply valves. Carefully unplug the dishwasher from the electrical outlet. If the dishwasher is hardwired into your home’s electrical system, locate the breaker that controls its power supply and turn it off.
- Wait: After disconnecting the dishwasher from the power source, wait at least 10 minutes. This waiting period allows all the residual power in the appliance to drain and the dishwasher’s electronic control board to reset.
- Reconnect the Power: Reconnect the dishwasher to the power source after waiting. Plug it back into the electrical outlet, or turn the breaker back on if it’s hardwired.
- Turn On the Dishwasher: Finally, turn the dishwasher back on by pressing the power button on the control panel. Ensure no power outage could affect the success of your operation.
2. Checking and Tightening any Loose Wiring
Loose wire or disconnected wiring in your LG dishwasher can lead to the nE error code. Here’s a step-by-step guide on how to inspect and tighten any loose wiring.
Please note: If you are uncomfortable with these steps or lack the necessary tools and skills, consulting with a professional electrician or appliance repair technician is always safer.
- Unplug the Dishwasher: Safety first! Ensure your dishwasher is turned off and disconnected from the power source before you begin. If your dishwasher is hardwired, turn off the breaker in your electrical panel that supplies power to the dishwasher.
- Access the Wiring: To access the dishwasher’s internal wiring, you’ll need to remove the bottom kick plate or toe panel. A few screws usually attach this. Use a screwdriver to remove these screws and gently remove the panel.
- Inspect the Wiring: Look for any loose, disconnected, or damaged connections. Pay particular attention to the wiring connecting the Vario motor, as a disconnect here could cause the nE error code.
- Tighten any Loose Connections: If you notice any loose connections, ensure they are adequately tightened. A pair of pliers might be needed to secure some types of connections.
- Reassemble the Dishwasher: Once you’ve inspected and tightened the wiring, reassemble the dishwasher. Reattach the toe panel or kick plate using the screws you removed earlier.
- Reconnect Power: Reconnect the dishwasher to the power source. If it’s plugged into an outlet, plug it back in. If it’s hardwired, turn the breaker back on.
- Test the Dishwasher: Finally, turn on your dishwasher and run a cycle to see if the nE error code has been cleared.
3. Replacing the Vario Motor
If your LG dishwasher displays the nE Vario Motor error and the previous troubleshooting methods have not solved the issue, the problem might lie with the Vario motor itself.
The Vario motor is integral to your dishwasher as it controls the spray intensity and direction. A malfunctioning Vario motor could lead to ineffective dishwashing and error codes. Here’s a guide on how to replace the Vario motor.
This task may require technical proficiency and should be done by a professional if you’re uncomfortable doing it yourself.
- Disconnect Power from the drain and inlet hoses: Before starting, disconnect your dishwasher from the power source to avoid electrical shock and turn off the water supply. If your dishwasher is hardwired, switch off the dedicated circuit breaker.
- Remove the Dishwasher: You must remove the dishwasher from under the countertop. This often involves removing a couple of screws that attach the dishwasher to the countertop and sliding the dishwasher out.
- Access the Vario Motor: The Vario motor is typically located at the bottom of the dishwasher. You may need to remove the dishwasher’s lower back panel to gain access.
- Disconnect the Vario Motor: Before removing the Vario motor, you’ll need to disconnect any attached wires. Note where these wires connect so you can properly install the new motor.
- Remove the Vario Motor: Every dishwasher model will have a slightly different method to remove the Vario motor. Generally, it will involve unscrewing bolts holding the motor in place, and then carefully removing it from its slot.
- Install the New Vario Motor: Now, install the new Vario motor in the space where the old one was. Secure it in place using the bolts that were removed earlier.
- Reconnect the Wires: Reconnect any wires previously connected to the old motor. Make sure they’re connected in the same way they were on the old motor.
- Reassemble the Dishwasher: Now, reattach the back panel and slide the dishwasher back under the countertop. Secure it with the screws you removed earlier.
- Reconnect Power and Test: Finally, reconnect the dishwasher to the power source and run a cycle to see if the error code has been cleared.
Remember, replacing a dishwasher motor can be a complicated process. If you’re uncomfortable performing this task, consider hiring a professional appliance repair service.
4. Replacing the control board
The control board is the “brain” of your LG dishwasher, and if it’s malfunctioning, it could lead to several issues, including the nE error code.
Replacing the control board can be a complex process, and if you’re not comfortable performing this task yourself, it’s best to hire a professional.
However, if you feel confident in your abilities, here’s a general guide to help you:
- Disconnect Power: First, ensure your dishwasher is turned off and disconnected from the power source to prevent any potential electrical shock. If your dishwasher is hardwired to the house’s electricity, switch off the corresponding circuit breaker.
- Access the Control Board: The control board is typically located behind the control panel on the door of your LG dishwasher. You must remove the screws holding the inner door liner to the outer door panel to access it.
- Disconnect the Control Board: Before removing the control board, you must disconnect any wires attached to it. Carefully remove each connector, noting their locations so you can easily reinstall them on the new control board.
- Remove the Control Board: Once all the connectors are detached, you can remove the control board. It may be secured with screws or clips. Carefully remove any fasteners and lift the control board from the control panel.
- Install the New Control Board: Now, you can install the new control board. Ensure it is secured like the old control board, using the screws or clips you removed earlier.
- Reconnect the Wires: Next, reconnect all the wires previously connected to the old control board. Connecting these wires is essential for the dishwasher to function properly, so double-check your notes or take a picture before removing the old board.
- Reassemble the Dishwasher: After you’ve installed the new control board and reconnected the wires, you can reassemble the dishwasher. Reattach the control panel to the door and secure it with the screws you removed earlier.
- Reconnect Power and Test: Reconnect the dishwasher to the power source and turn it on. Run a wash cycle to see if the nE error code has been resolved.
