What does the Samsung washer SUD code mean?
The SUD error code on a Samsung washer (which some customers misread as 5UD) is caused by various factors. Unlike several other error codes, this error does not occur due to a faulty Samsung washer. Instead, it typically arises from using the wrong type of washing detergent, using excessive detergent, or not allowing the detergent to dissolve adequately in the machine.
Here are the details regarding the appropriate detergent type, the recommended amount of detergent, and the necessary steps to take if you encounter the SUD error code on your Samsung washer, even when using the correct detergent.
If your Samsung washing machine displays “SUDS” on the screen, it has detected an over-sudsing situation and will pause temporarily to allow the excess suds to dissipate.
This error message usually occurs when you use excessive detergent or the wrong type of detergent.
What is the meaning of a Samsung washer SUD Error Code?
Samsung’s latest washing machines have an automatic foam detector that monitors the amount of foam and soap in the drum during the wash cycle.
This feature is becoming increasingly crucial as excessive suds make it difficult for the Samsung washer to agitate the water effectively.
If there’s too much detergent in the Samsung washer, the display will show a SUD Error number, and the machine will slow down to let the foam dissipate before continuing the cycle.
The time it takes for the foam to go away depends on how much detergent is in the water, ranging from 5 to 40 minutes. During this time, the appliance will add extra water to ensure a thorough rinsing process.
An extra rinse long wash cycle helps break up suds bubbles more effectively. During the washing process, this additional rinse may happen multiple times to eliminate any remaining suds. The SUD, 5D, and SD codes correspond to different years of production, but they all share a standard feature.
The manufacturer suggests using a High-Efficiency detergent to avoid an extended washing cycle and achieve cleaner clothes.
What Is the Root Cause of the Samsung Washer SUD Error Code?
If you see the error code 5UD or SUD, it means there are too many soap suds in the washer drum, which may be caused by using too heavy soap residue too much or the wrong type of detergent.
When there is too much foam in the Samsung washer, it can cause problems with how it works correctly. To prevent this, the Samsung washer will automatically stop until the amount of suds, and excessive foam has decreased, and then it will resume from where it left off.
In some automatic Samsung washing machines, a sensor detects when too many soap suds are being produced, called an excessive SUDS sensor.
Most of the time, you don’t need to do anything if an error occurs. Just be patient and wait for a while, and the problem will automatically resolve.

Detergents are classified by their type.
Samsung recommends using a high-efficiency (HE) detergent designed for high-efficiency washers. These types of detergents have reduced sudsing capabilities to ensure optimal washer performance.
Modern Samsung washers that use less water require the use of high-efficiency detergents. If you use a detergent not designed for high-efficiency washers, you may experience excessive sudsing.
You can quickly identify high-efficiency detergents by looking for the letters “HE” on the label. These detergents are specifically formulated for use in washers that use less water.
High-efficiency detergents not only produce fewer suds but should also be better at eliminating stains and thoroughly cleaning your clothes.
A sensor that detects foam
Suppose the amount of foam in the Samsung washing machine drum is reasonable, but the SUD error message continues to appear. In that case, it could indicate an issue with the foam sensor or volume detector, which may require repair or replacement.
Filters that are clogged
The drain system consists of a hose, branch pipe, and sewer; its function is to remove the water and suds from the washer.
Specific garments may have small elements like buttons or beads that can get caught, leading to a potential blockage, and this can trigger the appearance of the SUD Error code on the screen.
A switch that operates under pressure
If the SUD Error code is displayed, it could be due to a faulty or damaged pressure switch, which needs to be fixed or adjusted by a skilled technician to resolve the issue.
A centralized command and control system
Of all the issues, control unit failure is the least common. Sometimes, even if there are no issues with the equipment, the error message may persist on the screen.
In such cases, the only solution is to contact a specialist to replace the faulty component.
What Is HE Detergent and How Does It Work?
Before we address the issue, it’s important to clarify that we’re talking about HE (high-efficiency) detergent.
So, what is it exactly?
Modern Samsung washing machines use significantly less water than older models did.
In the past, Samsung washing machines consumed up to 40 gallons of water per cycle, which required extra detergent to clean clothes effectively.
HE detergents are available in 1X, 2X, and 3X concentrations, indicated by the X.
The higher the X value, the less water you need for one washing cycle.
What to Do If You Get a SUD Error Code
If your Samsung washing machine shows the SUD error code, a simple solution is to turn off the washer and wait for it to fix the issue. Once the washer has determined the problem is resolved, it should resume the cycle automatically.
Remove Detergent Residue from the Surface
If you are using the correct amount of HE detergent but still experiencing issues, removing any detergent residue from the washer may be necessary to resolve the problem.
To eliminate any remaining detergent residue from your clothes, run a wash cycle at a high temperature without any items in the Samsung washers.
Once the wash cycle has finished, check the washer to ensure no remaining detergent residue is on its surface. If there is any residue left, make sure to remove it.

Drain the drain pump and clean the drain pump filter.
In the Samsung washing machine displaying the SUD error code, drain pump filters are commonly present and can be removed and cleaned.
The buildup of soap suds and other particles inside the drain pump filter and cabinet can cause the Samsung washer SUD error code to appear. To clean the drain pump filter, you should follow the steps below:
- Get a rag and towel to wipe up any water leaking from the faucet or showerhead.
- Have a shallow container or bucket ready to collect the water from the drain pump.
- Locate the small access door on the left side of your washer’s front.
- Place the towel on the floor under the access entrance, then close the door.
- Apply pressure to the access door to open it.
- Wipe up any remaining water with the towel and keep it handy to catch any water that might spill during the cleaning process.
- Take the emergency drain hose from the container and put the spout over the container.
- Remove the cover from the drain hose and let the water drain into the container.
- Wait for 15 minutes to ensure that all the water has drained out.
- Rotate the drain filter counterclockwise to remove it.
- Clean any debris that has accumulated in the filter.
- Clean the filter and the cabinet to remove all debris, lint, and detergent residue.
If the filter is tough to clean, try running hot water over it or soaking it in hot water for a few minutes.
Ensure that the inlet and outflow holes are clear of any obstructions.
- Put the filter back in its place after cleaning it.
- Turn the filter top counterclockwise until it clicks and is tightly secured to the base.
- Replace the cap on the hose and put it back in the cabinet where it was.
- Close the access door when you’re finished.
Check the Foam Level Sensor to make sure it is working correctly.
Suppose you have followed all the suggestions mentioned above and are still facing issues with suds in the tub. In that case, it’s possible that the foam level sensor is defective and registers incorrect readings.
Although the steps mentioned below can guide you through testing and replacing the sensor, hiring a competent professional to perform the inspection and replacement is advisable.
To examine and substitute the foam level sensor, please follow these steps:
- Unplug the washer from the electrical outlet to ensure safety.
- Remove the front or rear access panel or control panel, depending on whether you have a top-loading or front-loading washer.
- Locate the foam level sensor. You may need to refer to the owner’s manual for assistance.
- Detach the wiring harness of the sensor from the rest of the system.
- Examine the foam level sensor using a multimeter to determine if it’s malfunctioning.
- Replace the foam level sensor if it’s found to be faulty.
To maintain the efficiency of your front-loading Samsung washing machine, we suggest using “HE” (High Efficiency) detergent, designed explicitly for such machines.
HE detergent boasts excellent cleaning performance while also producing fewer suds.
Using non-HE detergent in your Samsung washer may lead to excessive sudsing due to its high sudsing properties.
Make sure to use the recommended amount of detergent as the manufacturer suggested. Laundry detergent is available in different concentrations, such as 1x, 2x, and 3x. Adjust the amount of detergent accordingly.
