Samsung washing machine displays error SUD (5UD) or SD (5D) - what does it mean?

1. Information
2. Washing machines
3. Error codes
4. Samsung
5. SD/5D/SUD

You habitually stuffed the laundry into the drum, selected a program and turned on the wash, and after a while you discovered that your Samsung washing machine has stopped and the SUD, 5D or SD error is on the display. Through the glass of the hatch you can see a large amount of foam in the drum. It may even leak out of the detergent dispenser. However, there may not be foam, depending on the problem.

Error SUD / 5D / SD - what to do, how to fix it yourself

This error on Samsung washing machines is in most cases informational in nature, and you don’t need to do anything right now. Just wait 5 - 10 minutes, as soon as the foam settles, the machine will continue washing, and after it finishes, check:

• The drain filter may be clogged, causing excessive foam to form. Clean the filter. It is located in front of the washing machine in the lower corner behind the opening hatch. You can find more detailed information in the instructions for your machine model.
• Are you using hand washing powder that is not intended for automatic washing machines?
• Are you using too much laundry detergent? On average, no more than two tablespoons of powder are needed for 5-6 kg of dry laundry.
• Have you washed porous or fluffy items that contribute to increased foaming? When washing such materials in the future, use less powder.
• Try changing the detergent; it may be of poor quality or not suitable for your machine.

What to do if the wash does not complete, there is a lot of foam, and the Samsung machine constantly displays SUD, 5D or SD on the screen.
Then interrupt the wash: turn on the drain program or, open the washing machine door and take out the laundry. Then clean the drain filter and run the machine without laundry and detergent on a long washing program at a temperature of at least 60°C. This will help get rid of excess detergents that could clog the drain system of the machine.

The occurrence of this error in the absence of foam, unfortunately, most likely indicates a breakdown. However, first try to clean the drain filter of the machine and run the wash without laundry and powder on any program. If the SD/SUD/5D code appears on the display again, professional intervention is required.

What to do

The actions that a person should take when faced with the appearance of such an error depend on what caused it. First of all, you need to determine whether the drum is full of foam. If this is the case, you need to wait until most of the bubbles have settled. This takes 5-15 minutes. After this, the unit will start on its own.

If this does not happen, you need:

• interrupt the washing program;
• activate water drain;
• take out the laundry;
• run the machine without any clothes or powder to rinse it.

If there is no foam, you need to conduct diagnostics and determine what caused the error. The user can independently identify only a clogged drain filter.

Diagnostics

If error 5d occurs in the absence of foam, you must proceed according to the following instructions:

• press the power off button;
• disconnect the device from the electrical network;
• get underwear;
• clean the drain filter;
• run the washing machine without laundry and powder in any mode that involves heating the water to 60ºC.

If there is any water left in the drum, it must be drained before removing the laundry. This is done using the emergency drain tube located behind the filter cover.

If the error does not appear again, you can continue to use the washing machine.

If the device display continues to display fault code 5d, most likely the problem is a clogged drain filter.

How to fix

If the cause of the error is a clogged drain filter, you can fix the problem yourself by cleaning it. To do this you need:

• open the filter cover, unscrew it by turning it counterclockwise;
• rinse it under running water;
• look into the hole in which it is located and remove debris from the drain pump impeller;
• Replace the filter and the cover that covers it.

If the error is caused by excess foam constantly forming, you need to make sure that you are using powder for automatic washing machines and add it in smaller quantities. It is also wise to try using a different brand of detergent.

In addition, you need to take into account that when washing soft and fluffy items, the dose of detergent must be reduced, and for woolen items, use special powders or gels.

In what cases should you call a specialist?

If the washing machine displays error 5d when there is no foam and cleaning the filter does not solve the problem, you need to call a repairman, since the cause of the malfunction in this case may be:

• failure of the foam sensor;
• breakdown of the pressure switch that determines the water level, and in some models, foam;
• clogged pipe, hose or sewer;
• software failure;
• device processor malfunction.

You should contact a repair specialist if your washing machine drains water too slowly. This is the first sign of blockage, which will subsequently lead to operational errors.

The cost of the repair service for Samsung washing machines, depending on the type of fault and the pricing policy of the service center, ranges from 1 to 10 thousand rubles. The most expensive operation is replacing the processor.

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:

1. foam sensor failure;
2. breakdown of the pressure switch;
3. partial blockage in the elements of the drain system (hose, pipe, sewer);
4. 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 600C to wash out the 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:

1. disconnect equipment from communications;
2. remove the top housing cover;
3. Find the water level sensor in the upper corner of the washing machine;
4. remove the air duct;
5. disconnect flash drives with wires;
6. connect a new part;
7. 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

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

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

As for the “brain” of the machine, or rather the electronic board, we always recommend contacting a specialist with this problem. Both repair and replacement of this part have their own nuances, which cannot be neglected, otherwise you can damage the equipment even more. But don't worry ahead of time. If the sud error appears on the display, the likelihood of a control module failure is very low.

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!

   Answer

5d error value

The signal indicates that too much foam has formed in the drum. In Diamond machines from the manufacturer Samsung, foam control can be passive or active. With active control, the machine independently suppresses high levels of foam.

If the device cannot cope with the amount of foam, it displays error 5d. After this, the mode changes from active to passive. Passive control implies natural settling of foam. This process takes a lot of time.

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.
