Error meaning SUD, SD, 5D
Most often, the appearance of the SUD value on the washing machine display (in some models it may be designated as SD or 5D) is not at all a reason to panic and urgently call a technician. In numerous cases, this indicates that the level of foam inside the device is too high. You can verify this by looking at the loading hatch or opening the powder cuvette. Modern Samsung machines are equipped with foam formation control, and in cases where there is a lot of it, the suppression mode is automatically launched.
The SUD error code that appears indicates that the problem could not be resolved, so the device has stopped working and is waiting for the foam to settle. As a rule, the user does not need to do anything; within ten minutes the washing machine will continue to operate itself. Some models may ask you to press the “Start” button to continue working. But sometimes the amount of foam does not decrease, and the fault message continues to light up continuously on the display. In such cases, you need to know how to fix the breakdown and eliminate the causes of its occurrence.

Reasons for the SUD error
As a rule, increased foam formation occurs in the following cases:
- Use of hand washing products. They do not contain the defoamer added to automatic powders, so they should not be used in a washing machine.
- The use of counterfeit or low-quality powders.
- The dosage of detergent has been exceeded. In cases where bulky, porous or downy items are washed, it is recommended to reduce the amount of powder. If concentrate powder is used, it must be added in small quantities according to the recommendations on the package.
If there are no complaints about the detergent, the malfunction could arise for the following reasons:
- Blockages in the drain filter, hose or drain. In these situations, during an idle wash, the machine drains water for a very long time, and a SUD error occurs with the detergent. This indicates that the blockage has partially clogged the system; the remaining small hole is sufficient to drain water, but not enough to discharge foam.
- The foam sensor or pressure switch, which controls the foam level in some models, is broken.
- Failure in the electronic control board.
To determine the cause of the breakdown and eliminate it on your own, you need to know what to do in the situation that arises.
Error value
Those who speak English well can easily understand what the SUD error is telling the user. These three letters are taken from the word SUDS, which means soap suds. It is not difficult to guess that this code did not appear by chance, but because too much foam had formed in the car. In more detail, this error means that the washing machine has entered the mode to eliminate large foam formation in the drum. Just for everything, she stopped for 5-10 minutes so that this foam settled, and then the washing process continued.
Not all Samsung washing machines have the Sud error, but this does not mean that nothing happens with increased foaming. It’s just that different models of washing machines have different codes for the same error. An analogue of this error are codes 5d and Sd, they are the same thing because the number 5 and the letter s are not distinguishable on a small display of the equipment.
Note that even without knowing the exact decoding of the code, you can understand the reason for the machine stopping if you carefully look at the drum. You can't help but notice the large amount of foam.
How to fix the problem yourself
If more than ten minutes have passed since the error appeared, and the foam level has not decreased and the SUD error continues to appear on the screen, you should turn off the machine, unplug the power plug and remove the laundry. If the hatch is blocked, you must drain the water through the filter or emergency drain located behind the decorative panel at the bottom of the device.
Next, you need to clean the filter under running water, the drain hose and the sewer using a cable, and also free the cuvette from any remaining washing powder. After cleaning, run a new wash cycle without laundry or powder at high temperature to flush out any remaining detergent from the system.
If, after starting a new program, the SUD code appears again or in situations where it lights up on the screen and no foam is visible, this may indicate a malfunction of the foam formation or water level control sensors, which in a number of Samsung washing machines perform the function of controlling the amount of foam.
The foam control sensor cannot be repaired and must be replaced. It is very difficult to do this yourself; it is recommended to contact a service center and call a specialist who will select the appropriate part and install it correctly.
If the water level sensor (also known as a pressure switch) breaks down, you can fix the problem yourself. To do this, you need to perform the following steps:
- unplug the washing machine, unscrew and remove the top cover;
- find the pressure switch located in the corner;
- disconnect the air duct and move it aside;
- disconnect the wires from the faulty part;
- connect a new water level sensor;
- Reassemble the machine in reverse order.
In very rare cases, the SUD error indicates a breakdown of the control board. It is not recommended to repair this part yourself, because it can cause even more damage to the washing machine. In this situation, you need to call a qualified specialist and trust him to fix the problem.
How to find and fix the problem
What to do if a SUD error appears in a Samsung washing machine? The error usually does not interrupt the wash; we wait until it resumes and ends. After its completion, you should check:
- Is the drain filter clogged? You can find it by opening a special small hatch at the bottom of the unit. Remove and clean it according to the operating instructions.
- What type of powder was poured in. Often, beginners simply confuse the types for hand washing and those for automatic machines. A product that is too cheap and of poor quality should be replaced.
- Was there too much powder added? It is recommended to pour on average no more than two tablespoons per 5-6 kilograms of laundry.
- Whether there were fluffy or porous clothes in the drum. Such things foam the powder a lot, and for such washing it should be added less than usual.
It happens that the machine cannot cope with excess foam, constantly giving out “SUD” and not finishing the wash. In such a situation, we interrupt the procedure ourselves - turn on the water drain and remove the laundry from the drum. Then we clean the drain filter and start the drum cleaning mode, while it should be empty. If there is no such mode, run any long-term program, setting the temperature to at least 60 degrees.
DE error on a Samsung washing machine - what it means and how to fix it
The “SUD” message, called without foam, indicates a breakdown in the machine itself. For prevention, you should try the previous option - clean the filter and drum. If these actions do not change the situation, you will have to send the washing machine for repair.
Bottom line
So, one of the most popular codes that the machine displays on the screen, indicating a malfunction, is the SUD error. It means increased foam formation inside the drum.
As a rule, the owner of the device does not have to call a technician. Such a malfunction indicates improper use of the powder or a clogged drain system.
In some cases, the SUD error code indicates a malfunction of the foam sensor or pressure switch. The first one cannot be repaired; you should call a specialist to replace it; the second one can be changed on your own.
In the rarest situations, this error occurs when the control unit is faulty. In this situation, you should call a qualified technician from the service center to diagnose and carry out repair work.
How to fix it?
If we are talking about a large amount of foam or the use of unsuitable washing powder , then no technical intervention is required. You just need to change the detergent or reduce its dosage for washing. In the case of foam, the machine itself will continue to work as soon as its level reaches a certain point. But after the washing is completed, you should definitely start the program without using powder. There is no need to put laundry in such a “idle” wash.
Such a launch will make it possible to clean all the insides of the part. In addition, to ensure that the machine is clean, you should wash the drain pump filter.
If we are talking about a malfunction of the foam sensor, you just need to replace it. Although sometimes it happens that it is simply clogged. Therefore, you first need to clean it, and then start the washing machine. If the situation repeats, then this indicates a malfunction of the foam sensor, and it must be replaced.
Not all models of washing machines from the manufacturer in question are equipped with such a part as a foam sensor.
But to prevent clogging of the drain pump filter, it is necessary to use only high-quality gels and washing powders in the correct dosage.
The pump concentrator flushing procedure should be performed from time to time, regardless of whether the error in question appears on the display or not. It often happens that the problem of foaming is caused by blockages on the mesh or foreign objects.
If the pump does not work normally, then in order to make sure of this, it is necessary to dismantle it and then connect it directly to the power supply via an adapter.
Before starting, you must press the impeller with your finger. If you can easily hold it, the part should be replaced.
If we are talking about a malfunction of the pressure switch, then it should be said that in a large number of models of Samsung washing machines, this device is responsible not only for measuring the water level, but also for controlling foam formation. If this part is faulty, then you should inspect it and either repair the fault or simply replace it. To inspect and gain access to the part, you need to remove the top cover, and then find the pressure switch, which is located in the upper right corner.
Now you need to clean the sensor tube from debris and straighten it if it is pinched in some place. The contacts of the part should be inspected and cleaned. If the device does not work properly, the pressure switch is replaced.
If problems are observed in the control unit , due to which the indicated error occurs, then you should turn off the Samsung washing machine from the network and restart it after 5-10 minutes. If nothing has changed, then you need to call a washing machine repair specialist to your home. If the technician finds out that the control board processor is intact, then this failure can be corrected by repairing the board itself.
If the processor burns out, then in this case all that remains is to replace the entire control unit.
Summarizing all of the above, it should be noted that error 5d (Sd) on a Samsung washing machine can appear for a number of reasons, ranging from physical and mechanical to software. At the same time, its appearance allows the user to quickly understand why it occurs and check what exactly the problem is. Although in some cases it is definitely not possible to set up the operation of a Samsung washing machine without the involvement of a qualified specialist. But in the vast majority of cases, the user can do this on his own.

Error Sd (5d) on a Samsung washing machine: causes and solutions
Modern models of Samsung washing machines, for example Diamond WF8590NMW8 or WF8590NMW9, give their owners the opportunity to independently diagnose breakdowns. This was largely possible thanks to special information codes that appear on the display in the event of a malfunction.
Error Sd (5d) is due to excessive foaming
So, if letters or numbers suddenly appear on the washing machine display, and the washing stops for some unknown reason, it means that the machine is signaling a breakdown. In this article we will tell you what the Sd (5d) error means on a Samsung washing machine, what are the reasons for its appearance, and how to fix the problems associated with it.
Error Sd (5d) may also be indicated by the letter combination Sud (5ud). These information codes mean the same thing - there is too much foam in the washing machine.
Reasons for the error
If the SD code is displayed on the washing machine display, there is no need to panic. This error most often goes away on its own, you just need to wait a little.
Most models of modern automatic machines are equipped with a special sensor that ensures that too much foam does not form inside the drum.
Sometimes this function is performed by a pressure switch - a device that controls the water level required for each washing cycle.
With an increased level of foam formation, the sensor adjusts its operation in such a way as to extinguish a further increase in the amount of foam.
The SD information signal lights up if the measures taken cannot reduce foam formation. The machine stops working for a while until the foam settles. After the parameters become acceptable for further washing, the equipment will turn on itself and complete the cycle. In some Samsung washing machine models, you will need to press the “Start” button to resume washing.
Excessive foaming may occur in the following cases:
- the use of a powder intended not for automatic, but for hand washing (the latter foams very strongly, while the product for automatic machines contains special substances that suppress excessive foaming);
- exceeding the powder norm;
- using low-quality laundry detergent;
- washing fluffy or porous items without reducing the amount of washing powder.
These are the most common reasons why an SD code appears on the information display, but there are others. If the washing machine does not start washing even after the foam has completely settled, or the error appears again and again for no apparent reason, the problems may include the following:
- the foam level sensor or pressure switch has failed;
- there are problems with draining water;
- There was a failure in the washing machine control module.
