When the nF error code, which stands for ‘No Fill,’ is displayed, it indicates that your Samsung washer is not filling with water correctly. This could mean that it is receiving some water, but not enough to run a cycle, or it could mean that your washer is not receiving any water at all.
There are a number of potential causes of this problem, with the most common being an issue with the water supply hoses. Below, we will run through the most likely culprits causing the nF error on your washer and provide step-by-step instructions for fixing it.
The mesh filter screens sit at the ends of the water supply hoses and stop debris from entering your washer. However, over time, they can become clogged, hindering the water supply to your washer, and triggering the nF error code.
If this is the case, cleaning them will resolve the problem. You can do this by taking the following steps:
If the water supply hoses are kinked, clogged, or not connected properly, the water supply will be interrupted, causing the nF error. To ensure they are functioning as they should be, pull your washer away from the wall and inspect the hoses.
Ensure the hoses have not been pinched or become kinked, and then check the hoses are connected securely to the washer’s water inlets and the water supply faucets on the wall. It’s important that both the hot and cold water supply hoses are connected, and that the hoses go to the correct corresponding hot and cold water inlets on the washer.
Finally, ensure the water supply faucets are turned on all the way so they’re fully open, otherwise the error will persist.
If the drain hose is loose or not installed correctly, it can lead to siphoning, which means water will drain out of the washer as quickly as it fills. To ensure this isn’t happening, check the following:
Sometimes, a hard reset can resolve the nF error on Samsung washers. That’s because it could be a temporary software glitch that is causing the error to appear. To perform a hard reset, simply unplug your washer, wait for 5 minutes, then plug it back in again and attempt to run a cycle.
If one of the water inlet valves is faulty, it can cause the nF error code to appear, meaning that the water inlet valve will need replacing. However, testing them requires you to disassemble the washer, so call in a professional if you don’t feel comfortable doing this. Here are the steps to test them yourself:
The pressure switch monitors the water level in the washer. If it’s faulty, it may send an incorrect signal stating that the washer is not filling, causing the nF error. You can test it by:
If after running all the troubleshooting steps above the nF error code is still displaying on your Samsung washer, it may be time to call in a professional to inspect and fix your appliance. That’s because there could be a more complicated issue, such as a problem with the control board, which is not something you can usually fix yourself.
