Samsung dishwasher errors

Any system error on a Samsung dishwasher takes the user by surprise. I urgently need to wash the dishes, but here it is, the machine refuses to work, and even displays a strange code on the display. To solve the problem, you need to have a reference book on hand where error codes for Samsung dishwashers are deciphered. But what to do if you don’t have it at hand, but there is a breakdown? Refer to our article and use it to figure out what error is “plaguing” your dishwasher and what it means.

Diagnostic features

We will certainly provide a list of error codes with transcripts below, but now I would like to say a few words about how to correctly interpret these transcripts. Many novice craftsmen are very angry at the developers of the Samsung dishwasher self-diagnosis system. They say they came up with a system of codes that do not indicate a breakdown at all, but rather confuse the technician.

In reality, you just need to understand the principle of how to use decoding and what to look at in order to accurately determine what is broken with the machine. And, of course, you need to gain experience. Golden rule: when any system error occurs, a breakdown of the control module cannot be ruled out. The technician must always keep this in mind, and if checking the primary causes does not yield anything, you need to look at the secondary causes, of which the first is a defect in the control module.

It is not easy for a novice technician to identify a defect in the control module, much less eliminate it.

If the defect points to a specific part, for example a pump, you need to check not only this part, but also its power supply wiring, as well as the bus on the control board that is responsible for it.Decoding error codes for different dishwashers this is just the beginning. The more comprehensively you approach the search for possible faults, the more successful they will be.

Meaning of codes

So we got to deciphering the self-diagnosis system of the Samsung dishwasher. In this paragraph we will provide the error code, the defects that caused this error and talk about what needs to be done to eliminate them. Let's begin!

1. E1 This code indicates that the machine is taking too long to fill with water. This may be caused by a water supply shutoff, a clogged or squashed inlet hose, or a clogged in-line filter installed in the inlet valve thread. To solve the problem, you need to check the water supply and hose. You also need to clean the flow filter on the inlet valve.
2. E2. An indication that there are problems with waste water disposal. Perhaps the drain hose is simply pinched or clogged. Maybe the garbage filter or one of the pipes is clogged, or maybe it’s all about the pump, you need to check it. To begin with, forcefully drain all the water from the machine using the button, and then check all the specified parts one by one. Most likely, there is a blockage somewhere.
3. E3 The water remains cold. The heating element is responsible for heating the water; it is checked first. Secondly, we look at the thermostat, and thirdly, we pay attention to the wiring and bus of the control module. You can get to all these parts through the side wall of the Samsung dishwasher.

To check these parts you will need a multimeter. If you don't know how to use it, it's better to call a professional.

4. E4 The circulation system is full of water. Water may flow into the machine excessively if the fill valve is not completely closed.The problem may also arise due to a pressure switch (level sensor) or an electronic module. The check begins with the filling valve, then moves on to the pressure switch, and from there to the electronics. Unusable parts need to be replaced.
5. E5 Error indicates insufficient water pressure. Why does this happen? Firstly, because the pressure switch is faulty, it does not tell you how much water has already been pumped in, whether or not it is necessary to open the filling valve. Secondly, because the inlet valve or inlet hose is clogged. Thirdly, the pressure in the water supply dropped significantly. How to fix the problem? You need to start by checking the intake valve and hose, and then move on to the pressure switch. Focus on the electrics of the level switch.
6. E6, E7 These two errors have the same meaning - a problem with determining the water temperature. As a rule, in such a situation the machine simply does not heat the water, and some users mistakenly think that the heating element is broken. In reality, it is necessary to check and replace the temperature sensor, since this part cannot be repaired.
7. E8 This error tells us about a defect in the water flow distribution valve, or as it is also called an alternative valve. To eliminate the problem, you need to get to this valve through the right side wall of the dishwasher, check its resistance, and if it is broken, replace it.
8. E9. This code indicates a defect in the button that starts any dishwasher program. The reasons may be: short circuit or contact wear. You will have to disassemble the control panel in order to clean the button contacts. If this does not help, you will have to replace the contacts.
9. E.A. This error tells us that there is a little more water in the machine than needed. Most likely, the pressure switch is lying.Typically, this problem occurs due to a clogged level sensor tube, or because it is in the wrong position. Solution to the problem: checking the pressure switch, cleaning it and installing it correctly.

The point is that the dishwasher pressure switch must be installed strictly in the direction of water flow. A tilt to the left is acceptable, but not more than 30⁰, if the slope is greater, the sensor may not work correctly. Tilt to the right is not allowed.

The list of errors starting with the letter E is over, but this does not mean that the self-diagnosis system database is limited only to these errors. There are specific codes of 2 or even 3 characters, let's look at them.

1. 3E2 This code indicates that the signal coming from the tachometer has disappeared. This means that the control module does not know at what speed the motor is rotating. You will have to find this sensor on the engine body, check it, paying special attention to the supply wiring, and replace it if necessary.
2. Die. A rather specific code indicates an open dishwasher door. Perhaps the user simply did not close the door tightly, or there may be problems with the contacts on the lock. If you cannot close the door, you will have to disassemble it and look at the locking device and its contacts.
3. Le. This code appears when the leak protection system is activated. Most likely, the pan is full of water, or the contacts on the sensor are simply stuck. Remove the side wall of the machine, stick your hand into the tray and feel. If there is water there, you will need to drain it and look for the cause of the leak; if there is no water, move the sensor to remove the sticking.
4. Fe, He. These two codes may appear on machines with turbo dryers.The first code appears when foreign objects get into the fan, and the second when there are problems with the drying sensor. It is necessary to inspect, clean the fan and check the sensor. If necessary, both can be changed without any problems.

So, we studied and deciphered the errors of dishwashers. It is clear that you have dozens of additional questions that we anticipated. But we cannot answer in the format of this publication. Follow our articles and you will find the answers. Good luck!
