How to Fix SUD Error on Samsung Washer

Seeing a SUD error on your Samsung washing machine? Don’t worry—this is a common issue and usually easy to fix. The SUD (or sometimes shown as SD) error means your washer has detected excessive soap suds inside the drum, which can interfere with proper rinsing and spinning.

Here’s how to troubleshoot and fix the problem:

What Causes a SUD Error?

• Using too much detergent
• Using non-HE (High Efficiency) detergent
• Buildup of detergent residue inside the machine
• A partially clogged drain pump filter

Step-by-Step: Fix the SUD Error

1. Let the Washer Sit

First, let your washer sit for 5–10 minutes. Most Samsung machines will automatically try to fix the issue by pausing the cycle or extending rinse time.

2. Use the Right Detergent

Make sure you are using HE detergent only. Using regular detergent or too much of it can easily trigger this error. Run an extra rinse cycle without detergent to help flush out the excess suds.

3. Run a Rinse or Clean Washer Cycle

Remove all laundry from the washer and run an empty Rinse + Spin or Self-Clean cycle. This helps clear any remaining soap buildup.

4. Clean the Drain Pump Filter

If you have a front-load Samsung washer, there’s a small access panel at the bottom front of your machine:

• Place a towel and bowl underneath.
• Open the panel and remove the drain filter cap.
• Clean out any debris, coins, lint, or gunk.
• Reinstall the cap and close the panel.

Preventing Future SUD Errors

• Use only HE (High Efficiency) detergent.
• Always measure detergent carefully—a little goes a long way.
• Clean your washer monthly using a cleaner like Affresh® or vinegar.
• Regularly clean the drain pump filter to keep things flowing smoothly.

Still Seeing the SUD Error?

If the error keeps returning, the issue may be deeper—like a faulty pressure switch, drain pump issue, or even a control board problem. That’s when it’s time to call a professional.
