Samsung Washing Machine Error Code 4C: How to Fix It

Image

The 4C error on your Samsung washing machine typically indicates there is an issue with the water supply to your washing machine. In some Samsung washing machines, an issue with the water supply is indicated not by error code 4C but by error code 4E. 

This error can only occur at the very beginning of the washing process or while rinsing. Some common causes are no cold water in the system, dirt in the water inlet valve, issues with the connections hoses, or low water pressure. There are a number of quick fixes you can check and do yourself to hopefully get your machine up and running again before having to call in a repair technician. 

This is a step-by-step guide that covers how to fix a 4C error code on a Samsung washing machine.

Check the water taps

As the 4C error on a Samsung washing machine indicates issues with the water supply, the first step is to check both the hot and cold taps are connected and turned on. 

All you need to do is make sure they are turned all the way on and that there are no leaks. If not, open them and try your washing machine again to see if the error has been fixed. If you only do washes using cold water then you will need to install a “Y-connector”. This provides water to both the hot and cold hoses and should not cause a 4C error. 

Check the water hoses

The next component to check is the water hoses to ensure they are working correctly. The hoses get damaged easily, can bend out of shape or become blocked and are therefore the most common reason behind the 4C error. 

Follow these steps to check the water hoses:

  1. Turn the power off to your washing machine so you can work on it safely.
  2. Manoeuvre your Samsung washer away from the wall so you can access the back. 
  3. First, check that the hoses are properly connected. If they are not connected properly it can interrupt the water flow. 
  4. Cleaning out the hoses is the next step. Turn off the water supply then disconnect both ends of the hoses. 
  5. Run clean water through the hoses to check for blockages and leaks. 

Before you reconnect your hoses, move on to cleaning the mesh filters. 

Check the mesh filters 

While you have your hoses disconnected, it is a good time to check the mesh filters. The mesh filters are found where the water hoses connect to the Samsung washing machine. Follow these steps to check the mesh filters:

  1. Unscrew the filters and ensure they are clean and not blocked. Ideally, you should be checking them once every six months.
  2. If they are dirty give them a good clean and then reattach them. 
  3. Once clean, reattach the water hoses tightly.

Remember to clean your filters twice a year to prevent them from getting blocked and causing any errors. 

Check the detergent tray 

The next step is to check your detergent tray. If your detergent tray is clogged it will need to be cleaned. A clogged tray can interfere with water being able to fill into your washer. It is good practice to use high-efficiency detergent in your Samsung washing machine. Non-high-efficient detergent has a tendency to produce excessive suds which can stop the machine from detecting water flow. This may cause your washer to stop mid-cycle and produce the 4C error.

Check the water pressure 

You will need a water gauge for this next step in order to check the water pressure. In order for your washing machine to work correctly, there needs to be at least 10 pounds per square inch (PSI) of water pressure. If the minimum threshold of pressure is not met then your washing machine may not be able to fill up which results in the error 4C code. 

If you do not have a water gauge you can call your water supplier and ask them to let you know what your water pressure is. 

Reset your washer

The final thing you can try is to reset your washer. Resetting your washer involves cutting the power and waiting. This will force a reboot in the main control board which will reset any errors temporarily. Follow these simple steps to reset your washer:

  1. Disconnect your Samsung washing machine from its power source by unplugging it. 
  2. Wait two to three minutes.
  3. Reconnect your washing machine to its power source. 
  4. Turn on your washing machine and test it to see if the error remains. 

If none of the checks listed above have fixed the 4C error then you will need to contact a repair technician or the Samsung service center. There is a chance the issue is with the machine’s internal components which only a qualified technician will be able to confirm. 

These are a few things to note down and pass on to the professionals that may help them in diagnosing the issue and eliminate potential causes. By having checked these things yourself you may save the repair technician some time and yourself some money. 

You should also take note of when the 4C error is appearing. If it appears before the start of the rinsing mode, you can be confident the issue is not with the following:

  1. That there is no cold-water being supplied.
  2. That there is no power to the machine.
  3. That the drain hoses are not connected properly. 
  4. That the water pressure is not adequate when it is passing through the inlet hose.
