The washing machine is one of the most necessary laundry appliances nowadays. None of the housewives can imagine a daily routine without it, as it helps save time, energy, and health. It goes without saying that when your washer malfunctions, it makes you irritated and frustrated.
The NF Error on a washing machine often signals problems with the water supply. It can stem from issues like low water pressure caused by clogged filters or kinked hoses. Another culprit could be malfunctioning inlet valves that fail to open properly. However, it’s worth noting that other factors might also be at play, such as electronic glitches or sensor malfunctions within the machine.
Here, our skilled washing machine technicians at Spark Service PRO have prepared troubleshooting tips for one of the most common problems: the “nF” error displayed on your washer. This error is most common with Samsung, Speed Queen, Kenmore, Maytag, and LG washing machines.

A Very Common Error for Brands like Samsung, Speed Queen, Kenmore, Maytag and LG
NF error means “No fill”, indicating the washing machine cannot safely fill with water. An nF code appears on the display when your washer has spent over 15 minutes trying to fill itself up without success.
According to our experts’ experience, this NF code does not indicate severe damage to your appliances and can be fixed within several minutes. In this case, the main task is to identify why it happened. Let’s look at some of them:
- Water is turned on. Confirm if the water supply to the washing machine is activated. Typically, the washing machine necessitates both the hot and cold water supply valves to be opened. Ensure these valves are fully unlatched.
- The filter is clogged with debris. If your Samsung or Speed Queen washing machine has a debris filter, clean it with soap and water, then return it to the washer. This may resolve the nF error code.
- Door or lid switch problems. At times, it may fail to fill with water if the door isn’t shut properly. The door switch (for front-loaders) or lid switch (for top-loaders) signals the control panel or timer to initiate water filling once the door is securely shut. Even if the door closes correctly, there could still be an issue with the door or lid switch.
- Water inlet hoses. From time to time, water supply hoses may twist or fold, triggering the nF error code. Unfurl the hose if it obstructs the water flow to the washer.
- Water inlet filters are clogged. The majority of washers are equipped with filters situated where the water inlet hoses link to the machine. Clogged filters could result in an “nF” error. Switch off the water inlet valves and detach the hoses from the washer to inspect the filters. Identify the filters and assess whether they are obstructed. Depending on the washer model, you may need needle-nose pliers to remove the filter. Rinse the filters with water, employing a brush to eliminate any debris.
- Water pressure issues. Most washer models require water pressure between 30 and 120 psi. If the water pressure is below 30 psi, the washer will not receive enough water, and this will cause the nF error code.
- Water inlet valve issues. After verifying the potential causes outlined above for the nF error code, the water inlet valve’s solenoid may be faulty. Over time, the solenoid coils within the inlet valve may deteriorate. Employ a multimeter to examine the solenoids for continuity. If the coil continuity test yields negative results, it indicates that the water inlet valve needs to be replaced.
NB: Before accessing the washing machine, ensure the power is disconnected and the water supply is shut off. In the event of an nF error code, potential issues could include a complete blockage in the valves, a malfunctioning valve, a broken wire between the electronic control board and the water valves, or a defective electronic control board.

Frequent Asked Questions
What does the NF error code on my washing machine mean?
The NF error code indicates No Fill error, which means your washing machine is not receiving water as it should during the selected cycle. It's a common issue that can result from various causes.
Can I fix the NF error issue on my washing machine myself?
Depending on the cause, some NF error issues can be resolved by homeowners with basic DIY skills, such as checking water supply valves and cleaning inlet screens. However, for more complex issues like electrical component failures, it's advisable to seek professional repair assistance.
How can I determine if the water inlet valve is the problem?
To check if the water inlet valve is causing the NF error, you can perform a simple test. Disconnect the hoses and inspect the valve screens for blockages. Additionally, you can test the solenoids for continuity using a multimeter. If these tests indicate issues, it may be necessary to replace the inlet valve.
What should I do if I've tried troubleshooting but the NF error persists?
If you've attempted the troubleshooting steps in the guide but the NF error continues to display, it's best to contact a qualified appliance repair technician. They can perform a more thorough diagnosis, identify the precise issue, and carry out the necessary repairs or parts replacements to resolve the problem efficiently.
Is it cheaper to repair or replace a washing machine?
A relatively new washer may not break down on a regular basis, hence it may be more affordable to repair it. Getting replacement parts for modern machines can be easier than finding components for older models. We recommend the washing machine repair only when the repair cost is less than 50 percent of a new machine's price
How many years should a washing machine last?
A typical washer should last 10-13 years. Top-loading washers typically last a few years longer than their front-loading brethren. If you use a stacked washer/dryer combo, you may have to replace both if one starts acting up.
