Modern appliances feature built-in troubleshooting aides in the form of error codes or fault codes. Sometimes a top load or front load Samsung washing machine has trouble completing a function or is unable to move the next washing process. When this happens, the machine should display an alpha-numeric error code that can help you understand what problem the machine is experiencing.
Some issues can be resolved by a machine reset, while others require you to fix the problem before you can continue washing. This is the case when an E4 error code appears on the machine's display. This means there is a problem with the water supply system. The machine will not continue until that problem is fixed or the error is cleared.
What does E4 mean on a washing machine?
Several times during the washing process, the machine must empty and refill the drum with hot, cold, or warm water. If there is an issue with the water inlet or supply coming into the washer and not filling the machine, then the E4 fault code is generated. In short, there is something preventing the washing machine from receiving water.
Water fill and water drain functions have time allowances that give the machine plenty of time to fill, even if you have low water pressure or a slow flow of water into the machine. Typically, Samsung washing machines allow about 40 minutes for the machine to reach the proper water level during the fill process.
If the machine does not detect a change in water level after 6 minutes or if the machine is still in the filling mode after 40 minutes, then the machine will stop and generate an E4 code to indicate there is a problem with the water inlet or supply.
Fix E4 error code on Samsung washing machine
The E4 error code is a common fault that has some easy fixes and some fixes that may require a professional technician. The first thing you want to do is remove the main power supply by unplugging the machine from the wall outlet. This will prevent injury in case the machine starts suddenly. Also, unplugging the machine may be enough to clear the fault.
Some newer model Samsung washers experience a glitch that can present an error code when there really is no fault. Resetting the electronic system by powering down the machine for 10 minutes, then bringing it back online may solve the problem if it is an electronic glitch.
Check water supply
Typically, an E4 error will issue when there is a lack of water from your water valve into the machine. Therefore, check that the water supply faucets or valves that supply the washer are fully open and operational. You may even have to check your home or building's main water valve to make sure it is in the open position.
If it is winter and the temperatures are at or below freezing, then the water supply lines or drain hose might be frozen and need thawing.
Don't rule out human error. Make sure you have selected the right water volume level for your load. Lighter loads require less water than full loads, and having the option to wash a small load is one of your washing machine's energy saving features.
Remove any clogs
If the water valves are open and functioning properly, there may be a small object clog a water line or the cleaning filter at the entrance to the washer. This issue can also cause a 4E error code. You can fix this problem by locating the filter that mates the hose to the body of the washing machine. With the water supply turned off, unscrew the hose, remove the mesh filter, and clear any debris or rinse the filter clear of dirt.
The fine mesh filter is needed to remove impurities from tap water. When this inlet valve becomes clogged, soak the mesh screen in a solution of citric acid to remove the built-up limescale on the mesh filter. Or you can use a needle and a strong stream of water to clear the mesh pores that may be seriously clogged.

Water inlet valve is broken
If the washing machine doesn’t reach the proper water level or doesn’t fill with water at all, it could be a broken water inlet valve. The hot and cold water hoses that run from the machine are connected to your home's water inlet valve. This valve controls the flow of water into the machine and monitors the flow out through the drain hose. If this valve is broken, you will need to have it replaced to restore full water flow.
If you decide to fix replace the water inlet valve yourself, it must be the proper part that was built to fit the model of your washing machine.
Defective water level sensor/switch
The water level switch is an electromechanical device that controls the amount of water flowing into the machine. Some washing machines have an electronic water level sensor that sends a control signal when the proper water is reached. If the water level sensor has failed, it can no longer stop the water flow when the proper water level has been reached. To prevent a flooded floor condition, your washing machine is programmed to no allow water to flow if this sensor is not operating correctly.
If this is the problem with your Samsung washing machine, then it would be advised to have a technician diagnose the problem and replace the water level switch.
