Some days, nothing seems to go right. Whether you run out of milk for your coffee or you encounter a washing machine error code on laundry day, it’s the small, seemingly insignificant things that can ruin your mood.
Not to worry, we’re here to help you resolve a common Samsung washer error code and turn your day around.
In most cases, an NF error code will clear after you remove obstructions and straighten kinks in the hoses. If none of that works, you might have to replace a faulty internal component to get your washer to fill up with water.
Here, we will delve into the most common causes of an NF code. We will also walk you through all the steps to troubleshoot the error.
What does the NF error code on my Samsung washer indicate?
A Samsung washing machine NF error code stands for No Fill, which indicates that the unit is unable to fill with water.
The most likely cause of an NF error is a kink in the supply hose or an obstruction in the mesh filter. It can also be caused by a faulty component, which may require replacement.
How to Troubleshoot the NF Error Code in a Samsung Washer
If an NF error code appears on your Samsung washer, confirm that the water supply is connected and the valves are open.
Inspect the hoses for kinks, obstructions, and loose connections, then straighten them out if you find any. Clean out any debris that may have gathered in the mesh filters.
Below, we made a list of the most common causes of the NF error on Samsung washers. Start by troubleshooting the minor issues and work your way to the more complicated fixes.

Kinks and Obstructions in the Water Inlet Hoses
There are two types of water supply hoses connected to your Samsung washer—one for hot and one for cold. When you’re installing the hoses, you must connect them to their respective valves.
The valves are color-coded to make it easier for you to determine which hose goes where. Red is for hot, while blue is for cold.
Make sure the other ends of the hoses are connected properly to your water supply tap. Sometimes, fixing an NF error is as simple as turning on the taps.
If the hoses are installed properly and turned on when the NF error appears, you might be dealing with kinks and blockages in the water inlet hoses. These issues can restrict the flow of water into your washer and trigger an error code.
Solution: First, check the flow of water from the hot and cold hoses. Then, inspect the hoses for kinks and blockages if the water doesn’t flow.
- Step 1: Unplug the washer, and turn off the water supply.
- Step 2: Rotate the hot and cold inlet hoses counterclockwise and pull them out.
- Step 3: Hold the loose ends of the hoses over a bucket.
- Step 4: Briefly open the water supply taps to check the flow of water from both hoses.
- Step 5: Inspect the hoses for kinks and bent areas if water doesn’t flow out of them. Straighten them out if you find any.
- Step 6: Check for possible clogs in the hoses as well. Remove any visible obstructions.
- Step 7: Reconnect both hoses and make sure the connections are watertight.
- Step 8: Plug in the washer and turn on the tap. Then, test if it fills with water.
If water doesn’t flow but the hoses are clear of kinks and obstructions, you most likely have a problem with the water supply. We recommend calling a plumber to help you resolve the issue.
However, if water does flow through the hoses, you may check the mesh filters for obstructions, as well as other internal components for possible damages. Dirty filters and faulty components can prevent your washer from filling properly.
Clogged Mesh Filters
As mentioned, your Samsung washer has two water supply lines. Each line has a mesh filter, which traps foreign substances from the water.
Without regular cleaning, the mesh filters can get clogged up with dirt and restrict the flow of water into your washer. It may prompt a No Fill error if your washer can’t fill up at all.
Ideally, you should clean the filters every 15 days or so. It will prevent dirt from accumulating in the filters and causing water supply issues.
Solution: To clean a water hose mesh filter, follow these steps:
- Step 1: Unplug the washer, and turn off the water supply.
- Step 2: Rotate the inlet hose counterclockwise and pull it out. Cover the hose with a cloth to absorb any accidental spills when you disconnect it.
- Step 3: Pull out the mesh filter by hand. Use pliers if it is stuck.
- Step 4: Use a cotton swab to clean the filter, or soak it in water until it’s clean.
- Step 5: Let the filter fully dry before reinstalling it.
- Step 6: Insert the filter back into place using pliers.
- Step 7: Reconnect the hose and make sure the connection is watertight.
- Step 8: Repeat the same steps to clean the second mesh filter.
- Step 9: Confirm that the connections are tight.
- Step 10: Plug in the washer and turn on the tap. Then, test if it fills with water.
Damaged Water Inlet Valve
The water inlet valve, also known as the water valve assembly, connects the hot and cold supply hoses to your washing machine. It controls the flow of water to your unit.
If cleaning the filters and the hoses won’t restore the full flow of water, you might be dealing with a faulty component. In such cases, there’s little you can do to repair it.
