A Samsung washer can only work correctly if it receives a steady supply of water. So, if the machine is displaying a 4C error code, that means there’s a problem with that water supply and cannot function as it should.

The 4C error code on a Samsung washing machine points to a problem with its incoming water supply. The root cause could be a lack of water pressure, a blocked or kinked water supply hose, or a blocked water hose mesh filter. The same error code could also appear if there is a blockage at the detergent dispenser drawer.

In this guide, we’ll dive deeper into what causes the 4C error code to appear on your Samsung washer and what you can do to fix it.

What The 4C Code Means On A Samsung Washer

Suppose your Samsung washing machine is displaying the 4C error code. If that’s the case, that means there’s a problem with the machine’s incoming water supply. 

This error code will get triggered when water does not flow into the machine quickly enough. The most likely reason behind this is that the water pressure or flow rate is too low. Ideally, the incoming water pressure must be between 0.5 and 8 bar for the washing machine to work optimally.

Possible Causes and Solutions

Several causes will trigger your Samsung washer to display the 4C error code. Externally, the problem could be with the incoming water supply or the water supply hose and its mesh filter

Internally, the detergent dispenser drawer could also be to blame.

Incoming Water Supply

What it is: Before troubleshooting your Samsung washer’s components, the first step you must take is to ensure that the incoming water supply is free from any problems. By this, we’re referring to your household’s water supply to the tap that supplies the washer with water.

Washer water tap is OFF

How it fails: There are several issues that can affect your incoming water supply. Firstly, check that your household is not experiencing a water supply disruption. You can do so by opening the kitchen sink tap and checking for water.

Next, check the tap that leads to your washing machine. It’s possible that the tap isn’t open all the way, thereby reducing the flow of water to the washer.

Lastly, your local climate could also be to blame. For instance, water pipes can freeze up during winter and prevent water from flowing to your washing machine.

How to fix: The solution to this issue will depend on the root cause. Assuming there is no water supply disruption, make sure that the water tap that supplies your washer is open all the way. If the pipe is frozen, keep it open and gently warm it up using a hairdryer.

Alternatively, you could also consult a qualified plumber to resolve any internal water flow problems.

Blocked Or Kinked Water Supply Hose

What it is: Your Samsung washer connects to the water supply tap via a water supply hose. This water supply hose is detachable, with one end connected to the tap and the other to the washer’s inlet valve. 

How it fails: Assuming there are no problems with the incoming water supply, the next part to troubleshoot is the water supply hose. If the 4C error code appears, the hose is likely blocked or kinked.

That hose can become kinked when the washer is placed too closely against the wall or if it was wrongly positioned. It can also become blocked if a buildup of dirt and debris forms inside it.

How to fix: To fix this, first shut off the water supply to the washer. Then, pull the machine away from the wall behind it so that you can check for any kinks in the hose.

Next, shut off the water supply and place a cloth underneath it. You’ll need to detach the hose from both ends and check it for any blockages. You can test and flush the hose at your kitchen sink by holding it up to an open tap.

Once you’ve cleared any obstructions, reattach the hose to the washing machine and its nearby tap.

Water Hose Mesh Filter

What it is: A small mesh filter is located at the part where the water supply hose attaches to the back of the washing machine. That mesh filter is designed to capture any dirt or debris that comes through the water supply hose and prevent clogs inside your Samsung washer.

How it fails: Here, the 4C error code could get triggered due to the mesh filter getting clogged. This problem can happen over a long period as the filter gets saturated with dirt and debris. 

When that happens, water will not flow fast enough into the washer, triggering the 4C error code.

How to fix: The solution to this problem is straightforward. Firstly, shut off the water supply to the washer and place a cloth underneath it. Then, unscrew the water supply hose where it connects to the washer.

Using a pair of tweezers or pliers, gently remove the mesh filter at the washer’s inlet. Wash it in the sink and brush off the dirt or debris trapped there. Then, place the mesh filter back into the inlet.

To prevent this from happening again, repeat this process twice a year.

Blocked Detergent Dispenser Drawer

What it is: The detergent dispenser drawer is located on the front of the washer, and it is removable. Water flows through this drawer and carries the detergents and fabric softener that you load into it.

How it fails: After a long time in use, the detergent dispenser drawer can get blocked. Typically, this happens due to a buildup of excess detergent that gradually becomes more significant over time.

At some point, the blockage can become severe enough to affect the water flow into the drum, triggering the 4C error code.

How to fix: Firstly, remove the dispenser drawer from its housing. You will not require any tools to do this. 

Then, check it for any foreign objects or buildups that could obstruct water flow. Finally, clean the drawer thoroughly under the kitchen tap and wipe it clean with a dry cloth.

Lastly, slide the dispenser drawer back into its housing.

How To Clear The 4C Error Code

To clear the 4C error code on your Samsung washing machine, you must first resolve the root cause using the steps described above. If not, the code will continue to show regardless.

Once you’ve completed troubleshooting the issue and fixed the root cause, then you can clear the 4C error code by performing a reset on your Samsung washer.

To do so, follow the steps below.

How To Reset A Samsung Washer

To reset a Samsung washing machine, follow these steps:

  1. Firstly, unplug your washer from its socket, or turn off the dedicated circuit breaker at your main electrical box.
  2. Next, wait for one to five minutes as the washer discharges any electrical charge it’s retaining.
  3. Lastly, power the washing machine up by reconnecting its plug to the wall socket or turning on the dedicated circuit breaker.

Once you’ve completed these steps, you can rest assured that your washing machine has been successfully reset.

How To Enter Diagnostic Mode

After you’ve addressed the problem and reset your Samsung washer, you might want to confirm that the 4C error code has indeed been cleared. You can do this by entering the washer’s diagnostic mode to check if the 4C or other error codes are still registering in the washer.

To enter diagnostic mode on your Samsung washer, follow these steps:

  1. First, start with the washer turned on. Then, press and hold the Delay Start and Soil Level buttons. The buttons might differ depending on your Samsung washer model, so please confirm by checking the user manual.
  2. Next, keep holding those buttons until you see all zeros on display and hear a chime.
  3. Then, press the Soil Level button until the letter D appears on display. That means the machine has entered the error code diagnostic mode.
  4. At this point, you can turn the jog dial to cycle through however many codes the machine has to show. Once you’ve reached the letter D on display, that means you’ve viewed all current error codes (if any).

If you do not see the 4C error code, that means you’ve resolved the issue.

How To Test Samsung Washer After Fixing It

The most effective way to test your Samsung washer thoroughly after a repair is to run a complete wash cycle from start to finish. You don’t necessarily need to load anything in the washer to do this, so testing with an empty drum is perfectly fine.

To do this, you can simply choose the shortest cycle available, such as the Rinse+Spin cycle available on many Samsung models.

Since the 4C error code refers to an issue with the incoming water supply, you’ll want to pay extra attention during the beginning stages of the wash cycle. Then, when you see that the washer fills up and begins the cycle without any problems, you can rest assured that the problem has been entirely resolved.
