What to Do When You See the Samsung Error Code SUD?
Seeing the Samsung error code SUD on your washer or dryer can be frustrating-especially when you’re just trying to finish a load of laundry. The good news? It’s a common issue and usually doesn’t mean anything is seriously wrong. In most cases, this error pops up due to excess soap suds inside the machine. Thankfully, it’s often something you can resolve yourself without needing major repairs.
Key Takeaways
- The Samsung error code SUD points to excess suds in your washer or dryer.
- Using too much detergent or the wrong type often causes it.
- Most cases are easy to fix with a few simple steps.
- If the error isn’t clear, professional help may be needed.
What Is the SUD Code Trying to Tell You?
The Samsung error code SUD means the appliance has detected too many suds during the wash or rinse cycle. When this happens, your washer or Samsung dryer will automatically pause to allow the suds to break down and drain properly. This is a built-in safety feature to protect the machine from overflow or malfunction.
It’s important to note that the Samsung dryer error code SUD or washer version isn’t a malfunction by itself-it’s the system working as designed to prevent damage and ensure efficient cleaning.
Top Reasons the SUD Message Appears
Excess suds can come from several common sources. Let’s break down the main causes behind the SUD error code.
Wrong type of detergent
Using regular detergent instead of high-efficiency (HE) detergent is one of the most common causes of this issue. Non-HE detergents create far more foam than your Samsung washer or dryer can handle, resulting in the Samsung error code SUD being triggered.
Clogged drain filter or pump
If the drain filter or pump is clogged, it can slow down water drainage. When the water lingers in the machine, the system may misinterpret the delay as a sudden problem. This can also trigger the Samsung dryer error code SUD, especially in washer-dryer combo units.
Faulty pressure sensor
In rare cases, the pressure sensor inside the machine could be misreading water levels or suds accumulation. If you’ve checked everything else and the code still shows up, this might be the root cause.

Simple Steps to Clear the SUD Error
Here’s what you can do to clear the Samsung error code SUD and get back to your laundry:
- Let the cycle finish: The machine often pauses automatically to reduce suds. Wait 5-10 minutes to see if the error resolves on its own.
- Run an extra rinse and spin: This can help flush out any leftover detergent and suds.
- Clean the drain filter: Remove the filter (usually located near the bottom front panel), clean it, and reinstall it securely.
- Switch to HE detergent and use less: Always use high-efficiency detergent and reduce the amount to about 1-2 tablespoons. A little goes a long way.
