How to Resolve 4C or 4E Error Code in Samsung Washing Machine

Samsung washer shows different error codes for different problems that the washer faces. The purpose of codes is to make the problem easy to fix without calling or taking help from a technician. 

One such code is 4C or 4E. The error code 4C or 4E is essentially a problem related to the water supply. So, we will go into detail about the code and how to resolve the issue that the code refers to. 

A main inlet hose is connected to the washing machine via an L-shaped arm fitting.

When Samsung Washer Displays 4c or 4e Error Code?

Samsung washing machine demonstrates a “4C” or “4E” error code when it discerns water supply issues. A water supply issue means any obstruction or restriction in the flow of water through the main inlet hose into the machine. If the Samsung washer perceives that the water flow is obstructed or the water pressure is insufficient, it signals a 4C or 4E error.

What Causes the Water Supply Problem? 

Many factors in the water supply system can contribute to restrictions on water flow or cause low water pressure. One of the common culprits is the low water pressure. 

According to Samsung, “The water pressure needs to be in the range between 0.5 bar and 8 bar. If the pressure drops below the lower range, the water will not flow with enough force. So the Samsung Washer shows a 4C or 4E error code.” 

Besides, a clogged, kinked, or damaged main inlet hose can also interfere with the proper flow of water. In case you don’t know, the main inlet hose is the pipe through which the water flows into the machine for a wash cycle. So apparently, any block and kink in it can limit the water flow.

Other triggering factors could be a partially closed water valve, faulty water inlet valve, or buildups in the hose mesh filter, which capture the foreign particles and prevent them from entering the washing machine. 

How to Fix the Issues Causing 4C or 4E Error Message?

Test the Water Pressure

There are different ways to check the water pressure in the water supply. We have established that the low water pressure is a crucial factor that triggers the washer to display a 4C or 4E error code. That’s why it is important to test and verify that the pressure is right in the water supply. 

But how do you gauge the water pressure? 

Use a Pressure Gauge

Well, first you can use a water pressure gauge if you happen to possess one. It will give you an accurate reading of the washing machine. However, this device isn’t available to most of us and one needs to purchase it to check water pressure. 

Measure the Flow Rate Haphazardly

In case you don’t have a pressure gauge, there are slightly easier and cost-effective techniques as well to measure the pressure. One of them is checking the flow rate. The flow rate of the water supply is the rate at which water is filling the washer or the water inlet valve discharging the water. 

It may seem a bit complex term to you. So, the easier way is to count how much time it takes to fill the container to a gallon mark. If it takes longer to fill a gallon mark, you should understand that the water pressure is not enough. 

Use Hose Nozzle

An even easier way to determine the right pressure is using a hose nozzle. The goal is to have a steady and strong stream of water when the hose nozzle is attached to the washing machine’s inlet hose. 

You can think of it this way: if the water pressure is too low, the stream will be weak and may sometimes even trickle; if it’s too high, the water will come out forcefully. That said, the ideal flow or pressure should be stable that is not too low or forceful. 

However, in most cases, the water supply gets disrupted by the low water pressure. So you only pay attention to if it is low or gentle. When you identify that the water pressure is not within the correct range, you can deal with the situation using the following procedures. 

Check Every Aspect of the Main Inlet Hose

Samsung washing machine’s inlet hose is the pipe that connects the washer to the water supply. Water comes through this hose to the washing machine during the wash cycle. If the water hose is clogged or kinked for any reason, the natural flow of water gets obstructed. 

That’s why it is important to check if the hose is in the right condition. Here is a step-by-step process to check its condition: 

  1. Before moving forward to inspect this inlet hose, turn off the water supply and unplug the machine from the electrical outlet. 
  2. Slide the Samsung washer a bit ahead to locate the main inlet hose at the back of the washing machine. It is usually connected to the water inlet valve.
  3. Check the hose thoroughly for any kind of obstruction, kinks, or leaks. If you observe any leaks or damage, the hose should be replaced.
  4. If you find that the hose is bent or kinked, make it straight or free of kink. 
  5. Ensure that the hose is securely connected to both the water inlet valve on the washing machine and the water supply tap. Make sure the connections are tight, and there are no leaks.
  6. Sometimes, the stopcock of the water supply tap remains partially open. Pay careful attention to it and ensure the stopcock is fully open.
  7. Once you have checked the hose, turn on the water supply tap and check if water flows freely through the hose. If it does, you should no longer see the 4C or 4E error.

Check the Water Inlet Filter 

Samsung washers are equipped with a mesh filter inside the water inlet where the water inlet hose is connected. The purpose of the filter is to collect any foreign objects and separate them from the water flow to the machine. Over time, these objects can accumulate and clog the filter, leading to reduced water flow and potential issues with the washer’s performance. 

As a result, a clogged mesh filter can trigger “4C” or “4E” error codes. If you suddenly have these error codes on the screen, cleaning the filter regularly can also help solve the problem. Here is the step-by-step method of how you can clean the mesh filter. 

  1. Unplug the power supply from the outlet to fully power off the washing machine.
  2. Turn off the water supply or close the stopcock valve completely to prevent any flow of water. 
  3. To locate the water inlet filter, you need to disconnect the water inlet hose from the washer. Because inside the water inlet, you have access to the mesh filter. 
  4. The water inlet hose is connected to the washer via an L-shaped arm fitting. Disconnect it carefully by turning off the screw. 
  5. Once the hose is disconnected, you can use the grip with your fingers to gently pull the mesh filter out. You can also use a piler to do the same.
  6. The filter might be full of debris, lint, and other particles that accumulate in the filter. First, use a soft small brush to clean and loose those particles. And then, rinse the filter under running water to remove all the particles. 
  7. Once the filter is completely clean, install it back into its initial place. 
  8. Tightly secure the L-shaped fitting at the back of the machine. In Samsung, you can easily do it by screwing or turning on. 
  9. Turn the water supply valve back on to restore the water flow to the washing machine.

Samsung recommends cleaning this mesh filter twice every year. If you experience water supply problems quite often, then it is recommended to clean the filter more frequently. Once you have cleaned the mesh filter, the “4C” or “4E” error code should be cleared away.

Clean the Detergent Compartment of the Washer

Once in a while, “4C” or “4E” error codes originate from the blockage in the Samsung washer drawer. The drawer has different compartments for putting washing products like detergent, fabric softener, stain remover, etc. Each compartment is designed to hold different washing products and provide laundry aids. 

If the 4C or 4E error code is still on the screen after attempting all the methods above, you can check the drawer for any obstruction and clean it. This may also resolve the problem quite effectively. 

Each compartment in the drawer are meant to use specific washing products, and always try to follow the manufacturer’s instruction while using these compartments. Samsung recommends High-efficiency detergent. So, you should also stick with this recommendation. 

Plus, when you use the wrong detergent other than the recommended one, your Samsung washer can display an SUD error code due to excessive suds residue.

If all the resolving method fails to remove this error code, you can contact an expert or Samsung customer support. However, after trying all the methods, reset your Samsung washer. Sometimes, resetting can also do the trick. 

Contact a Skilled Technician or Samsung Customer Support


If you have never seen error codes before on the panel of your Samsung washing machine, there’s no need to worry when you come across the 4C error on your Samsung washer for the first time. Samsung washers use distinct error codes to signify various issues they detect. For instance, the 4C error code points to a water supply problem, while other codes, such as the SC error code or U6  error code may signify drainage issues and unbalanced load, respectively. These error codes serve the purpose of alerting you to specific problems so that you can address them on your own.
