If you are currently searching for the most effective method for removing detergent suds Samsung washing machine, you have likely encountered a stopped cycle and a drum full of foam. This guide outlines professional strategies for clearing excess suds, addressing error codes, and preventing future over-sudsing issues to restore your appliance to optimal performance.
Understanding the SUD or 5UD Error Code
When your Samsung washing machine detects an over-sudsing condition, it displays the SUD error code or the 5UD message. This is a built-in safety feature designed to prevent the machine from overflowing or damaging its internal components. The sensor identifies that the volume of foam is too high to drain effectively, causing the washer to pause its operation until the suds dissipate.
The primary culprits behind this error are usually related to the type or amount of soap used. Front-load washing machine models use less water than traditional top-loaders, meaning they require less detergent. Adding too much soap, or using non-High Efficiency (non-HE) products, creates a volume of lather that the machine cannot handle.

Removing detergent suds Samsung washing machine: Step-by-Step Guide
Once the error appears, you need to intervene to clear the blockage. Follow these professional steps to resolve the issue safely.
Method 1: The Waiting Game and Rinse Cycle
The simplest fix is often patience. When the 5UD message appears, the washer will automatically pause and attempt to let the bubbles burst naturally.
- Wait it out: Allow the machine to sit for 15 to 30 minutes. The error may clear itself once the sensors detect a drop in foam levels.
- Run a Rinse and Spin cycle: Once the error code clears and the door unlocks, run a dedicated Rinse and Spin cycle without adding any detergent. This flushes out the remaining residue from the drum and the clothes.
Method 2: Neutralizing Foam with White Vinegar or Fabric Softener
If the suds are stubborn, you can use household items to chemically break down the foam structure.
- White Vinegar: Pour approximately one cup of white vinegar into the detergent drawer (or directly into the drum if the door can be opened). The acidity of the vinegar quickly collapses the soap bubbles.
- Fabric Softener: Alternatively, mix a capful of fabric softener with water and add it to the dispenser. The oils in the softener help reduce surface tension, eliminating the suds.
- Flush the System: After adding the agent, run a short rinse cycle to wash away the neutralized foam.
Method 3: Manually Draining and Cleaning the Filter
If the error persists, the foam may have clogged the drainage system. You will need to manually drain the water and clean the drain pump filter.

- Locate the Access Panel: Find the small cover on the bottom front of your machine.
- Drain the Water: Place a towel and a shallow basin on the floor. Pull out the emergency drainage hose, remove the cap, and let the soapy water drain completely.
- Clean the Filter: Unscrew the drain pump filter (debris filter). Rinse it thoroughly under hot water to remove lint and sludge. This step is critical because a clogged filter prevents the machine from pumping out the sudsy water.
Preventing Future Over-Sudsing Issues
To avoid facing the SUD error code again, you must adjust your laundry habits and maintain your machine.
Use the Correct HE Detergent
Samsung front-load washers are designed strictly for HE detergent (High Efficiency). These formulas are low-sudsing and powerful enough to clean clothes with minimal water.
- Check the Label: Ensure your detergent bottle has the “HE” logo.
- Measure Correctly: Never eyeball the dosage. Use the manufacturer’s recommended amount, or even less if you have soft water, as soft water creates lather more easily.
Regular Maintenance with the Drum Clean Cycle
Residue builds up over time, which can contribute to sudden sudsing. Run the Drum Clean cycle (or Eco Drum Clean) once every 40 washes.

- No Detergent: Do not add detergent or clothes during this cycle. It uses high water temperatures and high-speed spinning to sanitize the drum.
- Remove Buildup: This cycle flushes out detergent residue from the hidden crevices of the tub and the drainage hose.
Utilizing Samsung Smart Care
If you continue to experience issues, use the Samsung Smart Care app. This diagnostic tool can scan the error code on your washer’s display panel to confirm if the issue is strictly over-sudsing or if there is a mechanical failure with the pressure sensor or drain pump.
By sticking to HE detergents and performing regular filter maintenance, you can ensure that the task of removing detergent suds Samsung washing machine owners dread becomes a thing of the past.
Frequently Asked Questions
What does the SUD or 5UD error code mean on a Samsung washer?
The SUD or 5UD error code indicates that the washing machine has detected an over-sudsing condition. This occurs when there is too much foam for the machine to drain effectively. The washer will automatically pause to allow the suds to dissipate to prevent damage to internal components or overflowing.
What is the fastest way to neutralize excessive suds in the drum?
To quickly collapse soap bubbles, you can pour one cup of white vinegar or a capful of fabric softener mixed with water into the detergent drawer. The acidity of the vinegar or the oils in the softener break down the foam structure, allowing the machine to proceed with a rinse cycle.
Why does my Samsung washing machine keep getting suds errors even with little soap?
This often happens if you are using non-HE (High Efficiency) detergent or if there is a buildup of residue in the system. Additionally, if your home has soft water, detergent will lather much more easily, requiring you to use significantly less soap than the manufacturer recommends.
How do I clear a suds error that won’t go away on its own?
If the machine remains stuck, you should manually drain the water using the emergency drainage hose located behind the access panel at the bottom front of the unit. Once drained, unscrew and clean the drain pump filter (debris filter) to ensure no soapy residue or lint is blocking the drainage system.
How can I prevent sudsing issues in the future?
Always use detergent labeled with the HE logo and measure the amount carefully rather than “eyeballing” it. You should also perform regular maintenance by running the Drum Clean or Eco Drum Clean cycle every 40 washes to flush out any lingering detergent residue from the tub and hoses.
