How to Fix Samsung Washer Error SUdS
Problem: Excessive suds detected

How to Fix SUdS Error
1. This code means the machine has detected too many suds. The washer will automatically try to correct this by pausing and adding time to the cycle.
2. Do not add more water or open the door. Allow the machine to finish its suds-reduction routine.
3. To prevent this, always use High-Efficiency (HE) detergent. Reduce the amount of detergent used, especially for small loads or if you have soft water.
4. After the cycle is complete, run an empty ‘Clean Washer’ or ‘Rinse & Spin’ cycle to clear out any residual suds.
