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 is malfunctioning, this makes you irritated and frustrated.

Washer NF Error Code

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 FIX Appliances CA prepared the troubleshooting tips when you face one of the most common problems – “nF” error displayed on your washer. This error is the most common if you have Samsung, Speed Queen, Kenmore, Maytag or LG washing machines.

Please note that this is a general troubleshooting guide, and specific washing machine models may have variations in their components and diagnostics.

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.

Upon the experience of our experts, this nF code does not mean 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 out the filter with soap and water and 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 might require needle-nose pliers to extract the filter. Rinse the filters with water, employing a brush to eliminate any debris.
  • Water pressure issues. As a rule, 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, it’s possible that the water inlet valve’s solenoid is faulty. Over time, the solenoid coils within the inlet valve may deteriorate. Employ a multimeter to examine the solenoids for continuity. If the continuity test for the coil yields negative results, it indicates that the water inlet valve requires replacement.

NB: Before accessing the washing machine, ensure to disconnect the power and shut off the water supply. In the event of an NF error code, the potential issues could range from 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

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.
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.
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.
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.
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
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.
