What Does The “Nf” Error Code Mean On Your Washer?

Getting an error message while doing your laundry can be stressful, making it more annoying if you have no idea how to fix it.

You can get several errors, each representing a different problem. Some faults occur due to minor issues that you can DIY easily, while others require professional help.

If you are getting an “NF” error code on your washer, don’t fret because it is a minor issue that you can fix easily.


“NF” stands for “no fill” and indicates that your machine is not filling up with water. The washer will display the error code when it has spent 15 minutes or more filling up water with no success.

If you are at the wits-end of dealing with the NF code, read further as we enlighten you about the meaning of error code and the easy steps to fix it.

The Meaning of “NF” Code

The Meaning Of &Quot;Nf&Quot; Code

After you turn it on, your washing machine first adds water. There is no way a machine can start the cleaning without an adequate amount of water.

Normally, it requires 19 to 22 gallons of water per load, depending on its size and efficiency.

If your machine cannot fill up with water, you will see an NF error on your display indicating the issue. Here’s how you can fix it.

8 Ways To Fix the “NF” Error Code

Ways To Fix The &Quot;Nf&Quot; Error Code

Several reasons, like clogged mesh filters, blocked hoses, and closed taps, can disrupt the water flow inside the washing machine.

Let’s dig in more to find out the solutions.

1. Check the Water Supply

Check The Water Supply

We often start checking the washing machine to see the problem, but the solution is fairly simple. Before you examine your machine, check your water supply at home by opening the kitchen and bathroom taps.

If you are getting a good water flow, it means you have some issue with the washing machine; otherwise, no water supply is the main culprit.

2. Inspect the Hoses for Blockage

Inspect The Hoses And Faucet For Blockage

Washing machines have fill hoses connected to the washer from one side and to the faucet from the other. If your machine is not filling up with water, check if the faucet is open.

If that is not the case, then examine the hose. Unthread it from the fixture, thoroughly check for any dirt or debris around the hose and replace it in case of any damage.

3. Examine the Water Inlet Valve

Examine The Water Inlet Valve

Washing machines have water inlet valves that control water flow during the filling cycle. If your washing machine displays an NF error code, a faulty water inlet might need your attention.

To check the working of the valve, unplug the washing machine and use a multimeter to check the working of the solenoid.

If you find any fault in the working, replace the entire valve. It is a pretty easy task, but you can also get professional help.

4. Investigate a Faulty Lid Switch

Investigate A Faulty Lid Switch

A lid switch is a safety mechanism that allows the washer to start filling up water once the lid is closed.

If your machine has a faulty lid switch, it might never signal the appliance to start resulting in no water filling.

To solve this issue, you must remove the lid to access the switch for examination. Perform a continuity test to check the flow of the electricity through it.

You can easily replace the lid switch to get things working normally.

5. Look Into a Damaged Selector Switch

Look Into A Damaged Selector Switch

Advanced washing machines come with a selector switch that allows the user to select the temperature for the cycle.

According to the instructions, this switch signals the water inlet valve to supply hot or cold water.

If the selector switch is damaged, it won’t signal the valve to add water resulting in the NF error message.

You can access the solenoid of the selector switch and check its current flow with a multimeter for a better diagnosis.

6. Check the Pressure Switch

Check The Pressure Switch

The pressure switch determines the water level in your washing machine.

If this switch is faulty, it won’t signal the valve to supply water resulting in “no fill”.

Like other switches, you can also check its current flow with a multimeter and replace it if needed.

7. Examine the Leakage

Examine The Leakage

You can get an NF error if your machine leaks and fails to keep the water inside the tub.

There are several reasons why your washer can leak; common ones are loose/punctured drain hose, faulty drain pump, and worn-out tub-to-pump hose.

In any case, it is better to check the root cause of the leak and get it fixed for its proper working.

8. Thoroughly Clean the Filters

Thoroughly Clean The Filters

Washing machines have two types of filters, one is a mesh filter, and the other one is a debris filter. Sometimes if they are clogged, it can also result in a poor water supply.

A mesh filter in a washing machine filters harmful foreign substances from the water.

Similarly, the debris filter captures dirt from clothes like lint, human hair, pins, etc.

You can clean these filters with water or a soft brush and place them back to check if your machine is working properly.


The rust in the water supply hoses also causes clogging in mesh filters. Experts recommend cleaning it regularly for efficient performance.


“No Fill” is a common error message you can get while doing the laundry. There are several reasons for this issue, but the common ones are crimped hoses, clogged mesh filters, or faulty switches.

Knowing the reason and easy ways to fix the problem is good for efficient performance.

If you cannot find the exact reason for this error, it is better to get professional advice and diagnose the problem.
