When the system fails to detect the presence of a water supply, the Samsung 4E error code dishwasher is displayed. First and foremost, it is necessary to determine whether the water entering the dishwasher is coming from an external source.

Before proceeding, check the water supply to ensure that everything with the valve is in working order. Take a pressure reading because a low-pressure reading may result in the error code 4E.

Turn off the power to the appliance and make sure the supply valves are not closed. If this is the case, turn them clockwise and then counter-clockwise to get them out of the way.

E4 Error Code Dishwasher: DESCRIPTION

Examine the hoses that are connected to the faucet. They should be in good condition, smooth, and free of inflections. Disconnect them from the machine and place them in the bucket, after which you will turn on the supply valve to the machine. If the water is flowing normally, this indicates that the hoses are not obstructed.

Is this the first time you’ve encountered the error 4E? For 10 – 15 minutes, turn off the electricity to the appliance. In the event of a control module failure, this should be of assistance.


If the hoses are in good condition, the pipeline is operational, the valves are open, and the reset did not resolve the problem, immediate action should be taken. It is necessary to examine the entire system, right down to the chips.

1. The filter has become clogged

At the point where the hose connects, there is a fine mesh to prevent kinking. It protects the valve from being clogged with debris. It is recommended that the system be cleaned twice a year in order to avoid the error code 4E.

  1. Remove the hose from the machine after it has been turned off.
  2. Using pliers, remove the filter from the machine.
  3. Make sure the holes are clean.
  4. Place the mesh in the appropriate location.

2. Water hoses connected incorrectly to the hot and cold water sources

It is important not to mix up the hoses that are connected to the pipes that have the appropriate temperature. In this case, error 4E may occur, although this problem has a different error code than the previous one.

3. A problem with the wiring

Using a screwdriver, carefully remove the top panel and check that the valve winding is connected. The loops’ connections should be secure and reliable at all times. Inspection of the wiring harness connected to the control board and testing with a circuit analyzer will follow.

It should either be repaired or replaced, depending on the extent of the damage. This should be of assistance in resolving the samsung dishwasher 4e error code.

The next step entails checking the wiring that runs from the base of the door to the main module for damage or fraying. This is accomplished by removing the front panel, which may contain some rusted or broken areas, by unscrewing the screws. Examine everything with a circuit analyzer and replace the contacts if they are damaged.

4. Failure of the drainage system

The drain hose may have been installed incorrectly in some cases, resulting in the Samsung error code dishwasher being displayed. The reason for this is that it is not connected to the detergent drawer (the transparent pipe is torn, pinched, or not connected).

5. The failure of the inlet valve

If the wiring and drain system are in proper working order, use a circuit analyzer to measure the resistance of each solenoid coil. Remove the dishwasher’s valves first, then connect the water supply and the electromagnetic coils in a series of connections to a 220 V voltage source alternately.

A blown solenoid will result in the valve, not opening, resulting in the error code 4E being displayed. Testing for this should be done by measuring the resistance at each of the outputs. The normal resistance should be between 2 and 4 kOhm.

There may be significant differences between models. It is possible to replace the defective part by removing it from another valve. This can be caused by a worn rod spring or membrane, which can be detected when the channel opens but does not completely close.

In this case, it is necessary to replace the entire assembly. A new valve will set you back more than $55.

6. There is a problem with the control board.

The final scenario associated with the error 4E is when the main module fails to supply voltage to the inlet valve through the circuit or when the main module malfunctions. Consult with a professional to have it checked and replaced (if necessary).
