Error 5d on a Samsung washing machine: what does it mean, what to do if Samsung issues code 5ud, sud, how to fix it yourself?

Samsung washing machines are reliable in operation, but no manufacturer of household appliances can guarantee 100% protection against breakdowns.

Therefore, during the next wash, each user has a chance to encounter a 5D or 5UD error.

Read the article about what the 5d error on the display that a Samsung washing machine displays means, and whether you can fix it yourself.

Decoding

Error 5D indicates excessive foam formation. It appears when there is too much of it in the drum.

Smart technology displays the 5D code on the screen and turns on the soap bubble suppression mode . Notice that there is more foam in the machine than is usually possible even without the 5D code.

It will be visible through the glass. Sometimes it leaks out of the detergent dispenser. If code 5d appears on the screen, but no excess foam is observed, then the reason lies in a problem with the equipment itself.

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.

Why does Samsung issue this code?

Error 5D is for informational purposes only. There may be several reasons for its appearance:

Incorrect calculation of the dose of powder or other detergent. If there is too much of it in the tray, excess foaming cannot be avoided.
The powder used was hand washable and not machine washable.
The detergent is of poor quality.
The drain filter is clogged.
There are porous and fluffy things in the drum, which lead to a lot of foam. If this is aggravated by even a slight excess of powder, then problems cannot be avoided.
The foam sensor has failed.
The water level sensor (pressostat) is faulty. In some Samsung washing machines, it not only measures the water level, but is also responsible for controlling the formation of foam. If this part fails, a 5D code will appear, although the amount of foam will remain within normal limits.
Clogged drain pipe, hose or sewer drain. If the hole is partially blocked, then the water will come out slowly, but this is not enough to remove the foam.
Malfunction or failure of the control unit.

Depending on the cause of the 5D code, further actions will differ. Sometimes you can solve the problem on your own, without calling a specialist to your home.

Step-by-step instructions for resolving error 5d

Signs of error 5d (SD, SUD) in Samsung SM	Help measures
There is a noticeable amount of foam in the washing machine, it operates in a modified mode, it may pause and be in standby mode.	Do not turn off the machine, allowing it to cope on its own. To speed up the process, you can press the Start/Pause button
The car has finally gone into standby mode, there is so much foam that it “crawls out” outside the hatch door.	Stop the washing process by turning off the SM. Carry out an emergency drain using the appropriate hose, clean the drain filter and run the device once without powder and things. When you subsequently start the work program, use only a high-quality product in a minimum sufficient quantity. It must be remembered that when washing porous or cellular items (tulle curtains) or fluffy items (sweaters, rugs), a very large amount of foam is formed, therefore, the amount of powder or gel must be reduced significantly.
Everything is observed, but foaming does not decrease.	Inspect the foam sensor, clean it, and replace if necessary. Inspect, clean or replace the pump. Wash the drain filter. Diagnose the pressure switch and control unit.

How to fix it yourself?

If error 5d is displayed on the display, no emergency measures are required. You just need to wait about 10 minutes for the foam to settle. After the specified period of time, the appliance will continue washing.

After completing the cycle, take the following steps:

Assess the condition of the drain filter. If a blockage has formed in it, it must be removed. The filter is located on the front wall of the device, in the lower corner, behind the opening hatch. After removing foreign objects, washing can be continued.
See what powder was used for washing. It must be marked “Automat”.
Estimate the amount of powder used. As a rule, a wash cycle with a load of 5-6 kg of laundry requires 2 tablespoons of detergent. More detailed information can be found on the package.
See what laundry has been washed. Fluffy materials require less detergent to care for.
Check the drain hose and the sewer hole in which it is located for permeability.

Sometimes it happens that the machine simply stops washing, and the 5D error is constantly displayed on the screen. In this case, you need to stop the cycle manually and activate the water drain program. After its completion, the drum flap is opened and the laundry is removed.

The first step is to manually clean the drain filter, and then run the device empty , without adding detergent. The water temperature should not be below 60 degrees. This measure is aimed at flushing the washing machine from excess foam that could clog the system.

What should I do if code 5d appears but there is no excess foam? This most likely indicates a breakdown of parts of the Samsung washing machine. In this case, it is better to seek the help of a specialist.

Troubleshooting procedure

In some cases, the washing machine does not resume the washing process, the foam does not disappear and the error continues to be displayed on the display. In such situations, the following steps must be taken:

interrupt the wash cycle using the “Stop” button;
start the water drain mode. If the program does not work, unplug the machine and drain the water in emergency mode;
remove the laundry from the drum;
clean the drain filter;
Wash the powder dispenser and drum to remove any detergent residue.

If error Sd (5d) occurs in the absence of foam, this may indicate a serious breakdown. First, try cleaning the drain filter and running a dry wash. There may be a malfunction in the electronic module. If the code appears on the display again, contact the technician.

The table provides a list of the most common faults that can be reported by the error code sud (5ud).

Signs of an error	Possible reasons	Remedies
Error Sd/5d/sud/5ud when there is no foam	Foam sensor failure	Part replacement
An error appears immediately after switching on or during the washing process (foam may be missing)	Malfunction of the pressure switch (in a number of models, the pressure switch not only measures the water level in the washing machine, but also controls foam formation)	Inspect the sensor, troubleshoot or replace the pressure switch if necessary
Slow process of draining clean water and error when draining water with foam	Clogged drain or sewer system	Cleaning the drain filter, hose and drain
Error anyway	Electronic module malfunction	Disconnecting the machine from the network and restarting again after a few minutes. If there is no result, call a specialist

You can clean the drain hose yourself; for this, use a special cleaning cable or another suitable item at hand.

If the error comes on during the washing process, but no foam appears, the problem is probably in the water level sensor (pressostat). With some home appliance repair skills, you can deal with this problem without the help of a specialist. To do this you need to do the following:

open the top cover of the machine;
find the pressure switch in the upper right corner;
clean the sensor tube from blockages or straighten it if it is pinched;
inspect and clean the contacts of the part;
if necessary, replace the pressure switch. Remove the tube, disconnect the wires, replace the part and reassemble everything in the same order.

Clean the powder dispenser, filter and drum of any remaining foam, even if the machine has completed the cycle on its own after an error occurred.

The error code in question is extremely rarely a sign of serious problems. Try to use suitable and high-quality detergents, do not exceed their dosage and clean the drain filter on time. By following these simple recommendations, you can avoid a number of problems with your washing machine.

When should you call a specialist?

There are situations that you cannot cope with on your own. A specialist should be called in the following cases:

The foam sensor is broken. Symptoms: code 5d appears on the screen, there is no foam in the drum, when starting the wash empty (without laundry and powder), the error continues to display. The cost of replacing the sensor is 1900 rubles, the price of the part itself is about 1000 rubles.
The water level sensor has failed (the pressure switch functions as a foam controller only in some Samsung models). Signs: the code is displayed immediately after turning on the washing machine or during washing, there is no excess foam. The cost of the work is 1900 rubles, the price of the part itself is 980 rubles.
A blockage has formed in the washing machine system (in the pipe through which water is drained, in the hose or in the area of the sewer hole). Signs: dry washing proceeds as usual, but the water takes a long time to drain, the error appears only when using powder. The cost of the work is 1300 rubles.
The control board needs to be replaced or repaired. Symptoms: code 5D is displayed, but there is no foam in the drum, the error appears even when washing without powder. The cost of work is 2400 rubles. If the board is burned out, you will need to purchase a new part. It costs from 5500 rubles and above.

Washing machine repair specialists can be found by adverts in the newspaper or on the Internet. In every city there are specialists providing such services. However, when choosing a specialist, you need to be vigilant so as not to encounter scammers.

The best option is to use the services of a specialist who has previously repaired equipment for relatives , neighbors or friends. If there are no recommendations, then it is better to contact the service center. The larger the organization, the better its workflow. Such companies have their own office and website where you can read reviews from other clients.

As a rule, calling a specialist to your home and diagnosing the breakdown is free of charge. The consumer pays only for the part itself and its repair.

Before you give money, you need to monitor the estimated cost of such work on the Internet. This will allow you not to overpay the master if he asks for too high a price.

Reasons for appearance

On Samsung washing machines, the sud error can be caused by various reasons. The main one is related to powder. The reason is this:

use of powder not intended for automatic machines. The fact is that special powders automatically add antifoam agents, but powders for hand washing do not contain them, so they cannot be poured into the washing machine;
low quality fake powder;
the dosage of powder has been exceeded. If things are bulky, it is better to reduce the amount of detergent or use a special powder. And if the powder is concentrated, then it generally needs to be poured strictly according to the dosage.

If the powder you use is beyond doubt, then the problem is that the washing machine is faulty. Such malfunctions include:

foam sensor failure;
breakdown of the pressure switch;
partial blockage in the elements of the drain system (hose, pipe, sewer);
control board failure, which is extremely rare.

What to do yourself, and what to turn to a specialist?

You can eliminate most of the reasons that caused the Sud error to appear on your own. The most important thing is to act consistently. First of all, wait until the washing machine itself tries to remove the foam. If the error still appears on the display, then do the following:

press the off button, then turn off the power to the machine;
open the drum and remove the laundry;
the door may be blocked, then drain the water from the tank through the emergency drain at the bottom of the machine or through the filter;
Be careful, prepare rags and a flat container into which you will pour the water.
rinse the drainage filter and run an empty program (without laundry and powder) with water heating to 60
0
C to wash out any remaining powder from the machine.

If, when performing this mode, the message sud appears again, then with a high probability we can talk about a breakdown of the foam sensor. It is not available in all washing models, and in some machines its function is performed by a water level sensor, which is often called a pressure switch. The foam sensor cannot be repaired and must be replaced. With this problem, you should contact a specialist who will find the necessary similar part and install it correctly.

If the pressure switch breaks down, you can do the repairs yourself. This part can be changed quite easily, you need:

disconnect equipment from communications;
remove the top housing cover;
Find the water level sensor in the upper corner of the washing machine;
remove the air duct;
disconnect flash drives with wires;
connect a new part;
assemble the machine.

In some cases, the system may display a Sud error if the foam does not leave the drum due to a partial blockage in the hose or drain pipe. These parts need to be cleaned. The drain hose is disconnected from the machine and cleaning is carried out using a cleaning cable. To rinse the pipe, you need to remove it from the machine. This can be done through the bottom of the washing machine, you need

put the equipment on its side;
if there is a bottom, remove it carefully;
release the clamps on the pipe that hold it on the tank and pump;
wash the part and return it to its place.

You may need new clamps after cleaning the pipe; they are usually replaced.

Thus, in most cases, you can eliminate the reasons that gave rise to the sud error yourself. The main thing is to be patient and act according to the plan. Good luck!

Prevention

To prevent your Samsung washing machine from displaying error 5d in the future, you need to take the following preventive measures:

do not use excess amounts of powder, strictly follow the recommendations for its dosage;
when washing fur and porous items, reduce the amount of detergent;
do not put powder intended for hand washing into the machine;
remove all small parts from pockets and shake out debris before loading into the drum - this will avoid clogging the filter and drain hose.

Additional functions

In addition to programs, Atlant washing machines also offer several useful functions that allow you to improve cycle parameters. Some are activated automatically, protecting equipment from excessive foaming, imbalance or overfilling, while others are turned on at the user’s discretion. We will analyze the most popular and convenient options in more detail.

Additional rinse. When this function is turned on, a second rinse is added to any program, which ensures that the detergent is completely washed out of the fabric. This is necessary if you are washing children's clothes or clothes for allergy sufferers.
Half load. Now you don’t have to wait until the basket with dirty laundry is filled to the top - you can wash a modest load without imbalance and unnecessary water consumption. With the half-load option, you can put fewer things in the drum, while the machine will work smoothly and use resources economically.
Refusal to spin. This option is necessary if items made from delicate fabrics, silk, wool and down are washed.
Easy ironing. Thanks to a special algorithm, things look smooth after washing, which saves time on ironing.
Water level control. This function allows you to save water consumption. Special sensors analyze the weight of the laundry loaded into the drum and calculate the volume of liquid required to wash it. Savings reach up to 10 liters per cycle.
Delayed start. With its help, you can start washing at any set time within 12-24 hours, for example, before returning from work or waking up.

Helpful information

Tips that will be useful to all owners of Samsung washing machines:

If a new powder was used for washing, and after using it, error 5D was displayed, it may be due to the poor quality of the composition. It is recommended not to use this product so as not to damage the washing machine.
If the device is under warranty and the breakdown is not related to external factors, you need to contact a Samsung service center. The manufacturer must correct the defect at his own expense.
Private craftsmen are required to provide paper with a stamp and signature. It must indicate the price, describe the service and note the warranty period.
If you have the appropriate skills, you can buy and replace a failed part yourself. This will save a significant amount of money.

Miele Foam Control System

Miele engineers took care of their consumers and equipped many devices with special “Foam Control” technology, which allows you not to worry about this danger. A sensor is installed inside the machine that reacts to the appearance of foam at the top of the tank. When it is triggered, the electronics will drain the water and refill it. This will happen until the foam leaves the tank. Foam Control technology protects both the Miele machine itself and the user's repair.

Magicka flies out. At a specific or random moment. Solution

You play for yourself, play and then - bam! - everything goes out, and now in front of you is a desktop without any hint of a game. Why is this happening? To solve the problem, you should try to figure out what the nature of the problem is.

If a crash occurs at a random moment in time without any pattern, then with a 99% probability we can say that this is a bug of the game itself. In this case, it is very difficult to fix something, and the best thing to do is just put Magicka aside and wait for the patch.

However, if you know exactly at what moments the crash occurs, then you can continue the game, avoiding situations that provoke a crash.

However, if you know exactly at what moments the crash occurs, then you can continue the game, avoiding situations that provoke a crash. In addition, you can download the Magicka save in our file archive and bypass the departure location.

Magicka has no sound. Can not hear anything. Solution

Magicka works, but for some reason does not sound - this is another problem that gamers face.
Of course, you can play like this, but it’s still better to figure out what’s going on. First you need to determine the scale of the problem. Where exactly is there no sound - only in the game or on the computer at all? If only in a game, then perhaps this is due to the fact that the sound card is very old and does not support DirectX.

If there is no sound at all, then the problem is definitely in the computer settings. Perhaps the sound card drivers are installed incorrectly, or maybe there is no sound due to some specific error in our beloved Windows OS.

Magicka gives an error about the missing DLL file. Solution

As a rule, problems associated with missing DLLs arise when starting Magicka, but sometimes the game can access certain DLLs during the process and, not finding them, crash in the most blatant manner.

To fix this error, you need to find the required DLL and install it on the system. The easiest way to do this is using the DLL-fixer

, which scans the system and helps quickly find missing libraries.
