Samsung Error Code Sud
Excessive suds
Common Causes
- 1Too much detergent
- 2Non-HE detergent used
Step-by-Step Troubleshooting
- 1
Let the washer sit for 15-20 minutes — it will attempt to reduce suds by repeatedly draining and adding small amounts of water
- 2
On the next load, switch to an HE (High Efficiency) detergent and use only 2 tablespoons for a regular load. Samsung recommends HE detergent for all models
- 3
Run an empty hot water cycle with no detergent to flush soap residue from the system. For heavy buildup, add 2 cups of white vinegar to the drum
- 4
Clean the detergent dispenser drawer — pull it out fully, disassemble the inserts, and scrub off dried detergent that can create excess suds during the rinse cycle
Pro Diagnostic Tip
If Sud code appears even with correct detergent and amount, the pressure switch may be misreading water level, causing the tub to fill too low and concentrate the soap. Check the pressure hose for partial clog before blaming the detergent.
You Might Also Notice
- •Visible suds coming from the door seal or detergent tray
- •Washer pauses frequently during the cycle
- •Rinse cycle takes much longer than usual
