Samsung Washing Machine Shows NF or 4E Error Code – What Does This Fault Code Mean?

If your Samsung front load or top load washer is displaying the error fault codes 4E or NF, you need to know what is wrong to repair your washer. These error codes will show on your Samsung washer if it detects a water issue. NF and 4E = No Water Feed = Washer Not Filling. This means that there is an issue that is preventing your washer from receiving water into the water inlet valve.

The troubleshooting steps below apply to all types of Samsung washing machines including front load, top load, and washer and dryer combos.

The first thing to do when you see the NF or 4E error code appear on your Samsung washer:
Step 1 – Remove the unit from power! Be sure the water supply valves on the wall behind your washer are fully open. These 2 water valves must be ALL THE WAY open to provide water to your Samsung washer. Turn them all the way counter-clockwise to be sure. If you have check valves on the wall, make sure they are turned all the way open and parallel with the water supply hoses. If both the water supply valves are fully open, proceed to step 2.

Be sure both water valves are open to supply water to your washing machineBe sure both water valves are open to supply water to your washing machine

Step 2Check to be sure the water supply hoses are not bent, crimped, or kinked. If the hoses are bent, this can prevent water from getting to your washer. Be sure that when you last pushed the washing machine back towards the wall, you did not inadvertently get the water hoses crimped behind the washer, as this happens often. To be sure, get a mirror and a flashlight and look behind your washer without pulling the washer away from the wall. If the water supply hoses are bent or crimped, slide the washer out enough to get your hand down there to get the water supply hoses straight so the water can flow properly. If the water supply hoses are too short, replace them with longer water supply hoses so the water lines do not get bent when you slide it back into place. If the water supply hoses are not crimped or bent, proceed to step 3.

Step 3Be sure there is nothing clogged inside the water supply hoses. To check this you need to turn off the water valves that supply water to the washer. Unplug the washing machine from power or turn off the breaker. Slide the washer out far enough to get to the water supply hoses that attach to the back of the washer. Remove the water supply hoses from the back of the washer. (Keep the water supply hoses attached to the water valves on the wall) Be careful as there may be water mesh filters installed in between the water supply hoses and the water inlet valve. If so put these aside and clean if needed. Get a bucket and be sure the water supply hoses are not clogged by slowly opening the water valve one at a time and let the water flow into the bucket. If the water flows freely then the water supply hoses are not clogged. This is to test to be sure the water is flowing properly from the water hoses and valves. If the water does flow as it should from the water supply lines proceed to step 4.

Step 4Check where the water hoses were attached to the washer. You will need to pull the washer all the way out so you can get behind it. The part that the water supply hoses screw into on your Samsung washer is the Water Inlet Valve or Valves. Check the water inlet valve to be sure there is nothing clogging or blocking the water from entering. There may be small water mesh filter screens on the water inlet valve that could be clogged, clean if needed. If you do not see anything clogging the water inlet valve or valves, proceed to step 5.

Step 5The water inlet valve itself may be clogged internally, have a loose electrical wiring connection, or the solenoids in the water inlet valve are not operational. If you suspect the water inlet valve is faulty or has a loose connection, you will need to open the washer up to gain access to the valve. Remove power first. Check to be sure that the wiring harness is connected to the water inlet valves. Be sure it is secure and not loose. If the wire connection is attached to the water inlet valve, you may have a bad or faulty solenoid in the water valve or valves. At this point you could test them with a multimeter or simply replace it or both.
NOTE: SOME Samsung washing machines have 2 water inlet valves, 1 for COLD water and 1 for HOT water. Other Samsung washers have a hot and cold water inlet valve as one part.

I started a load of towels yesterday and halfway through filling up it gave the 4E error and drained all over my kitchen floor. Is what I didn’t realize is that the towels had stuffing from a dog toy bundled up in one of the towels and I think it has my washing machine stopped up. It is a Samsung topload VRT and I have had it a couple of years with no issues. I think maybe some of the stuffing made its way under the tub and is throwing off the water level thing. How can I fix this without having to call for a service repair?

My issue is that my Samsung Washing Machine cold water inlet valve is ok itself, but the power to it is not connected or has a problem, as there is no input power to it blue cable when the program runs on cold water and when it runs on hot it is all good.


DIY Project Help Tips 3 DIY Project Help Tips March 9, 2017 at 12:01 am

Check to see if the wiring harness going to and from the water inlet valve is connected and secure.
If you find the wiring harness to the water inlet valve to be damaged, replace it.
Also be sure you have the cold water valve open.

Samsung eco bubble washing machine displaying error 4E. We have checked the water pressure this appears to fine. Checked the mesh in hose, this is clear, also cleaned out the filter. We have replaced the solenoid valve following the steps you advise on the web page, but we still continue to see the error 4E. The washer appears to work longer into the cycle but the error appears part way through the rinse cycle. The washer appears to fill and drain ok. What else could we do?

I have a problem my Samsung WA90F4- filling water more than enough then appear error 4E, I checked the filters its okay whats the problem plz?


6 Dede November 5, 2016 at 9:20 pm

My Samsung front load flashes the nf code and I have to set it on a different cycle then it will work.
Sometimes I have to do it a few times.
For months it was only one cycle that did it, but now it’s doing it on all cycles usually once per 2 or 3 loads.
It seems as if something is going out rather than an actual physical issue with the water flow.
Admittedly, I’ve not been able to check that.
I’m 53 and disabled and can’t get back there to look.
Haven’t been able to afford anyone to come take a look.
Can this be a parts issue or is it always a blockage issue?

My samsung washing machine shows 4E. There is no inlet problem as I could see water flowing inside the drum. But still not filling. I believe the water is just draining before filling/washing. How to fix this problem. Kindly help. Thank you.
Washing machine model: Samsung WA85V3

If your Samsung washer is draining and filling at the same time, check that the drain hose at back is not too far down in the standpipe. If so, it may create a siphoning effect and drain as it fills.

My Samsung washing machine stops after 6 minutes then displays the code 4E. What should I do?


DIY Project Help Tips 11 DIY Project Help Tips August 11, 2016 at 9:13 pm

Samsung washer 4E error code is a Water Supply Error.
Is the water tap connected to the washing machine and open to full?
Is there kinks or bends in the water hose connected to the washing machine?
Is the water hose mesh filter blocked or clogged?

Samsung aquajet washer will run the cycle but as soon as it gets to the “rinse and spin” it will stop and show the 4E code. why is that, what can i do to fix it?

Check the following areas on your washer:
– Be sure the water tap connected to the washer is fully open.
– Make sure there are no bends in the water hose connected to the washer.
– Be positive the water supply hose mesh filter is not clogged.

My Samsung washer will not quit filling. It displayed the code 4E so we checked everything. We replace the pressure switch and none of that helped.


DIY Project Help Tips 15 DIY Project Help Tips June 9, 2016 at 9:50 pm

Brandy Caywood,
Samsung washer error code 4E means the washer IS NOT GETTING WATER or NOT ENOUGH WATER.
If you are getting the 4e error code and the washer will NOT STOP FILLING, you most likely have a bad water inlet valve as one of the solenoids may be stuck in the OPEN position.
Check with meter to be sure.


16 Tim June 8, 2016 at 5:07 am

Just because it comes up code 4e, it could be something else. There’s a little tube on the bottom of the drum that sends water and tells the valve to close when it’s full. Open the back and put the hose on with duct tape. Samsung code 4e leaking.

My new sSamsung front loader keeps on giving the 4E code even after i found nothing wrong with the water inlet pipes?


DIY Project Help Tips 18 DIY Project Help Tips June 1, 2016 at 10:53 pm

If you have followed all methods for clearing the 4E error code on this page… contact Samsung if your fridge is new. Or call the company you purchased it from and let them know your issue.
Is it under warranty?

Samsung washer 4E error is a Water Supply Error.
Check if the water tap connected to the washing machine is open to full.
Check if there are no kinks or bents in the water hose connected to the washing machine.
Check if the water hose mesh filter is not blocked.

Samsung top load washer – Keep getting 4e error.
Just purchased the machine 3 weeks ago, we have well water so not sure if that is the cause.
Thinking about taking this machine back.


DIY Project Help Tips 22 DIY Project Help Tips April 13, 2016 at 9:23 pm

The Samsung washer error code 4E = No Water Feed = Washer Not Filling.
It most likely DOES have something to do with well water.
You will need to check the water pressure coming into your home and to the washer.

Make sure you have both water valves open and there are no bends or kinks in the water hoses.

The samsung wobble technology top load empties the tub as fast as water comes in so the tub never fills up in the first place.


DIY Project Help Tips 24 DIY Project Help Tips April 8, 2016 at 8:27 pm

You may have a siphoning issue going on with your Samsung washer. Make sure the washer drain hose is not pushed far into the draining pipe.
NOTE: A siphoning effect will happen if the drain hose is pushed in too far… thus causing water to come back into the washing machine or drain out as it fills.

My washer gives the NF code after it has filled all the way up. The entire drum is full of water which is way too much for this washer. I am able to empty it after I set it on the spin cycle. After going through the trouble shooting steps I think it might be a sensor, but I have no idea how to know or how to replace it.


DIY Project Help Tips 26 DIY Project Help Tips March 14, 2016 at 2:40 pm

NF means NO FILL, if your Samsung washer is filling TOO MUCH, there may be an issue with the board, water fill inlet valve, or a possible sensor. First be sure all wire harnesses are secure. If you find that you need to replace the board, valve or sensor, look on YouTube to find the correct video to assist you in repairing the washer yourself.
