The Samsung dishwashing machine is well-deservedly popular all over the world. It not only features unusual design solutions, but also attracts the attention of housewives with its simple interface and excellent functionality. The manufacturer managed to implement all modern developments in this dishwasher, constantly increasing its sales volumes. Each modern model has a system for self-diagnosis of possible breakdowns. In case of failure, the Samsung brand machine specifies which unit has lost its functionality and gives the user a corresponding signal. Today we will take a closer look at what error codes exist. Samsung dishwashers and what to do if they appear.
A few words about diagnostics
It should be explained how error codes are correctly recognized. The fact is that even service center technicians are sometimes dissatisfied with the self-diagnosis system developed by Samsung. They say that the dishwasher does not indicate a problem with its signal, but only creates some confusion.
First of all, a general rule: when any code is displayed, a failure of the module responsible for general control can never be ruled out.The repair specialist must always remember this, and when checking the primary causes does not yield anything, he should move on to secondary causes, the main of which will be a malfunction of the module.
When an error code indicates a specific element (for example, a pump), it is recommended to check not only it, but also the wiring that goes with it and the bus on the management board, which is responsible for proper operation.
Decipher error codes is considered an initial action, but the search for a breakdown should be approached comprehensively in order to achieve a positive result.
Signal meaning
We proceed directly to deciphering the readings of self-diagnosis of a Samsung dishwasher. We list the codes, probable defects that provoked a particular signal, and the main actions aimed at eliminating the problem:
- E1 – Using this code, the Samsung machine reports that the water intake has been taking too long. The reasons may be hidden in turning off the water supply, the appearance of blockages or squeezing of the water intake hose, or a clogged filter installed in the inlet valve. To fix the problem, you will have to check the presence of water in the water supply system and the condition of the hose. In addition, the valve filter is cleaned;
- E2 – the signal indicates that there are difficulties in removing dirty liquid. There is a suspicion that a blockage has formed in the water outlet hose, or it has been pinched somewhere. It is possible that debris has accumulated in the filter or in the nozzle; it is possible that the pump may break down. First of all, all water is forcibly removed from the Samsung dishwasher, after which all of the listed elements are checked one by one.It is more likely that the problem is hidden in the blockage;
- E3 – The dishwashing water does not heat up. The water heating element is responsible for this function and should be checked first. After that, we move on to the thermostat, then check the wires and the modular bus. It is possible to perform such actions by first removing the side panel of the Samsung dishwasher;
- E4 – the circulation system is overfilled. Water can fill the machine with excess if the water intake valve does not close. The reasons are hidden in the pressure switch or electronic module. First, the valve is checked, then the remaining elements. Those that fail are replaced with new analogues;
- E5 – The error code tells you that the water pressure in the machine is not strong enough. The problem may be explained by a breakdown of the pressure switch, which does not control the liquid level and does not send a signal to the water intake valve. It is possible that the valve itself or the hose is clogged. Another version is low pressure in the central water supply network. We check the valve and hose for water intake, after which we diagnose the pressure switch, focusing on the electrical part of the relay;
- E6 and E7 – such a pair of codes has the same interpretation, explaining problems with the temperature of the water. The dishwasher simply does not heat the liquid, and many consumers are beginning to attribute the problem to a failure of the heating element. In fact, you just need to inspect and replace the temperature sensor;
- E8 – the code indicates that the valve distributing water flows has failed.To fix the problem, remove the right panel of the Samsung dishwasher, find the specified element, check its resistance value and, if necessary, replace it;
- E9 – With this error code, the machine reports a defect in the button that activates the machine's programs. The main reasons are a short circuit or wear of the contact group. It is necessary to disassemble the control panel to inspect and clean the contacts. There is a possibility that they will need to be completely replaced;
- EA – The error indicates a violation of the water level in the dishwasher. Probably, the failure occurred in the pressure switch. As a rule, the problem is associated with the sensor tube, or the element itself is located incorrectly. The pressure switch is checked, cleaned, and set correctly.
Special signals
The main list of errors is listed in full, but the Samsung dishwasher has several specific signals, which include two and three symbols:
- 3E2 – With this code, the machine reports the loss of the signal supplied by the tachometer. Therefore, the control module does not recognize the speed mode of the electric motor. It is necessary to find this device on the motor body, inspect it (especially the wires) and replace it if necessary;
- Die – a very specific problem, signaling that the dishwasher door is not closed. There is a possibility that the user did not watch, or the contact located on the lock failed. If the door does not close, it must be disassembled and the locking mechanism checked;
- Le – such an error is possible if the system protecting against possible leaks was activated. Probably, a lot of water has accumulated in the tray, or the sensor contacts are stuck.It is necessary to remove the side cover of the dishwasher and feel the bottom of the washing compartment (drip tray). If there is water in it, you should drain it and look for the problem;
- U.C. – the signal indicates that there are problems in the electrical network with the voltage necessary for the normal operation of the dishwasher. To keep this issue under control, experts advise using a stabilizer device;
- Fe, He – This pair of codes is typical for Samsung brand dishwashers that have a turbo drying function. The first error means that there is a foreign object in the fan, and the second indicates that there is a problem with the drying sensor. We inspect and clean the elements or simply replace them.
