What is a Dishwasher NE Error?

The NE error code on your dishwasher’s display panel is more than just a random set of letters and numbers; it’s a cry for help from your appliance. This code specifically points to an issue with the water level sensor.

The water level sensor is a critical component that ensures your dishwasher fills up with just the right amount of water. If the sensor isn’t working properly, it could cause your dishwasher to underperform or even break down. When you see the NE error code displayed, it means the dishwasher is unable to continue its cycle until the problem is resolved.

Common Causes of the NE Error

The following are common causes of this error…

Faulty Water Level Sensor

A malfunctioning water level sensor is the most common reason for the NE error code. This can happen due to wear and tear, or because of a manufacturing defect. The sensor measures the amount of water in the tub and sends this data to the control board. If it can’t perform this task, the control board will trigger the NE error code.

Clogged Water Inlet

The water inlet is where the dishwasher receives the water it needs for its cycles. Over time, it can get clogged with food particles, mineral buildup, or other foreign objects. When this happens, it can interfere with the water level sensor’s ability to accurately measure the water in the tub.

Damaged Wiring

Damaged or loose wiring connecting the water level sensor to the control board can also trigger an NE error. This might happen due to vibrations from the dishwasher or from the wear and tear of daily use.

Initial Steps for Troubleshooting

Here’s how to troubleshoot the issue…

Turn off the Dishwasher

Your first and foremost priority is to ensure that you’re operating in a safe environment. Locate the power cable for your dishwasher and unplug it from the electrical outlet.

If your dishwasher is hardwired into the home electrical system, you will need to locate the circuit breaker that controls the dishwasher and flip it to the “off” position. Take a moment to double-check that you’ve cut off the power supply to avoid any electrical accidents.

Check the User Manual

Almost every dishwasher comes bundled with a user manual. This manual is a treasure trove of information. Flip or scroll to the troubleshooting section where you’ll usually find a list of error codes and the manufacturer’s recommended steps for resolving them.

Take note of any steps that are specific to the NE error on your dishwasher model, as these can offer tailored guidance on what to inspect or adjust.

Inspect the Water Inlet

Now that you’ve ensured the dishwasher is safely powered off, you can open it and begin your inspection. The water inlet is a critical component. It is usually located at the bottom or sometimes at the side of the machine.

Use a flashlight to look into the inlet for any debris, food particles, or mineral buildup that could obstruct water flow. If you find anything, use a pair of tweezers or a similar tool to carefully remove the obstruction. Please note that you’ll need your product manual for specific information on accessing this part.

Advanced Troubleshooting Steps

Here are some advanced troubleshooting steps…

Test the Water Level Sensor

To proceed with this step, you’ll need a multimeter. This tool will help you determine whether the water level sensor is functioning correctly. With the dishwasher still unplugged, locate the water level sensor. This is typically found near the bottom of the dishwasher tub.

Disconnect any wires or plugs connecting it to the machine. Set your multimeter to measure resistance (Ohms) and connect it to the sensor. If the reading is not within the manufacturer’s specified range (usually found in the user manual or a technical sheet), the sensor is likely defective and should be replaced. Please note that you’ll need your product manual for specific information on accessing this part.

Examine the Wiring

Faulty wiring is a less common but still possible cause of the NE error. Carefully trace the wires from the water level sensor back to the control board. Examine each wire to ensure it’s in good condition, securely connected, and showing no signs of wear or fraying.

If any of the wires are loose, you can typically tighten them with a screwdriver. If a wire appears damaged, you may need to replace it or seek professional help for more complex wiring issues.

Run a Test Cycle

You’ve made it this far, which means you’re ready to see if your hard work has paid off. Safely restore power to the dishwasher, either by plugging it back into the electrical outlet or by turning the circuit breaker back to the “on” position. Initiate a quick test cycle, which is usually a shorter wash cycle that checks all the functions of the dishwasher.

Keep an eye on the display panel to see if the NE error returns. If it doesn’t, congratulations! You’ve successfully troubleshooted the issue. If the NE error still shows up, you’ve done everything you can on your own, and it’s time to seek professional help.

When to Seek Professional Help

You’ve done a great job getting this far, but if the NE error persists after trying all the troubleshooting steps, it’s time to consult a professional. A certified technician can provide a more in-depth diagnosis and may need to replace faulty components to resolve the issue.
