How To Fix Samsung Washer ND Error Code

So your Samsung washer is displaying the ND error code on the control panel. You must be wondering what could have caused it and how you resolve the problem and resume normal washing. 

In this article, we’ll uncover precisely why this error code is displayed, and what it means, and offer a series of troubleshooting steps that you can take to fix your washer without the need for intervention from an appliance technician. 

What Does A ND Error Code Mean

The ND error code indicates a problem with the washer drainage. The most common diagnoses relate to a blocked drain filter, faulty drain pump, or obstructed hoses. The ND error message puts the washing machine into a basic safety mode setting whilst letting you know there is a problem with the drainage function. 

What Causes The Samsung ND Error Code

There are a number reasons why your washer is displaying the ND error code, all primarily related to drainage. From relatively simple issues such as a clogged drain filter or obstructed drain hose, through to more complex mechanic or electrical issues such as a faulty drain pump or blown control board. In this section I will outline each possibility and offer actionable advice to get your machine in good working order.

1. Clogged Drain Filter

A washing machine’s internal drain filter serves as a barrier to safeguard the pump from lint, and other potential debris that could be in the washer drum. Blockages will result in poor water drainage from the washer drum, which in turn could lead to minor flooding or leaks. The ND error code acts to prevent this situation by alerting you to the problem.

To guarantee the drain filter is functioning effectively, it should be cleaned every 6 weeks for optimal performance. To make sure your washer is running at its best, you should clean the filter after 40 wash loads, especially if you’re a heavy user. 

2. Blocked Drain Hose or Waste Pipes

An obstructed drain hose will trigger the ND error code, and it’s often a very simple and easy-to-resolve problem, once you appreciate how the hose becomes obstructed:

  • Clogging from debris or scum
  • Being bent, kinked, or crushed behind the washing machine
  • Running up a vertical loop, leaving the washing machine to literally pump wastewater uphill to clear the drum

Despite its rudimentary design, the drain hose is one of the most important components in the drainage system of your washing machine. It facilitates the removal of the wastewater throughout the wash cycle, not just at the end. 

3. Drain Pipe Not Syphoning

Drainage problems in your washer can occur due when there is no air gap for the drain pipe. Without an air gap, a vacuum is created within the pipe, causing the machine to start the draining process before it should, resulting in an ND error code

4. Faulty Drain Pump

The drain pump is a mechanical component with impellers that draw the waste water out of the drum throughout the wash cycle. If the pump becomes clogged, or the impellers get damaged, or break it will trigger a drainage problem . In some instances there may also be a problem with the pump electrical connectors. Whatever the root cause, the result of the pump failing to function properly will lead to the ND error code. 

5. Control Board Defect

The control board inside your Samsung washer is the main circuit board responsible for exchanging signals between different parts of the machine. You could think of it as the washing machine computer.

When the control board fails or malfunctions, you could see a variety of errors displayed, including the ND code. If everything within the drainage system inside the machine seems to work fine, it’s a sign that the problem may be within the control board circuitry.

Fixing Samsung ND Error Code

Now that we have outlines the primary reasons for the ND error code, we can follow a series of troubleshooting steps to diagnose and fix the specific cause on your machine.

1. Clean The Drain Filter

Cleaning the drain filter is a simple task that takes 15 minutes or less to complete. 

  1. Lay down a towel and place an empty bowl on the floor near it – these two items will come in handy as soon as you open up the cover.
  2. Carefully remove both the drain hose’s cap and its core so that water starts flowing out into your container. wait until all liquid has been collected
  3. Inspect the filter and remove any debris and wash it thoroughly in the sink
  4. Reinstall the filter and replace the hose cap

2. Inspect the Washer Drain Hose

Next check the drain hose. You are looking for any signs that would indicate the hose is prevented from permitting the waste water to drain. For example if the hose is crushed behind the washer, or if it is blocked or kinked. Follow these steps to inspect the drain hose.

To access your Samsung washer’s drain hose:

  1. First, move the appliance away from the wall so you can easily remove its clamp and separate it from its surroundings. 
  2. Inspect the drain hose surface looking for any visible damage such as cracks, kinks, or narrowing in the diameter that may restrict water flow. 
  3. Check the pipe for any internal obstructions or blockages. Run tap water through the hose to check if flows without restrictions
  4. If there are blockages inside the hose, use a drain snake to reach them and clear out any clogs that may be present.
  5. If the hose is damaged in any way I recommend replacing it, this is a low-cost component. 
  6. Finally, after replacement push the washer back towards the wall taking care not to crush or bend the hose. 

If you notice visible damage to the drain hose, you will have to replace it. Here’s a great video on how to replace this component.

3. Inspect Household Waste Pipes Are Clear

If your drain hose is clear and functional, it is possible that your sewer line has a blockage. Once the wastewater leaves the washer drum, it travels down the drain hose and away into your home’s sewer line. Unless it’s blocked. Here are two ways to check:

  1. If you remove the washer drain hose from the sewer line coupling, you will see the wastewater backing up to the pipe coupling and not clearing the sewer line waste pipe.
  2. Flush your downstairs toilet and check if it clears, if not, you can be certain of a sewer line problem. 

4. Check The Drain Pump Is Working

The drain pump is located inside the washing machine, and will require a reasonable level of technical understanding. Unless you are familiar with appliance mechanics, it may be worth calling a professional appliance repair technician for support at this stage.

Testing The Drain Pump

You will need a multimeter to check whether the drain pump is working. Once you grab a multimeter, follow these simple steps to conduct the test:

  1. Make sure the washing machine is unplugged
  2. You can get access to the drain pump by removing the side or rear panel of your washer
  3. Remove the connecting drain hoses and unscrew the drain pump
  4. Set your multimeter to the lowest ohm setting.
  5. Connect the leads of the multimeter to the pump’s terminals.
  6. There should be some continuity if the pump is working properly. You’ll get a reading of 5-10 ohms if the component is in good condition.
  7. If you get a reading of 0 or a number close to it, the pump needs to be replaced. The same goes if you get a reading of a high number or infinity.

5. Check The Control Board is Functional

If you have taken all of the steps recommended within this diagnosis guide, then the final check is to inspect and test the control board. It is important to test the control board functionality first-hand for confirmation and not presume it is at fault. Performing this type of test requires a reasonable degree of technical competence in electrical circuitry, so I would recommend you seek professional support from an appliance repair technician.

How to Test the Control Board

You will need a screwdriver and a multimeter to do this. Follow these steps to successfully test the board for continuity.

  1. Your first step is to ensure that the washing machine is unplugged.
  2. Take your screwdriver and use it to remove the screws that secure the control panel.
  3. You will find the control board behind the panel. Disconnect all of the wires from it and remove the board from the machine.
  4. Take your multimeter that’s set to the lowest resistance setting and connect the leads to the terminals of the control board.
  5. You will know that the board is defective if you get a reading of a high number or infinity.
