Washer-dryer combo displays SUD or SUdS and may pause while attempting to clear excess suds.

Safety first: Do not open the door mid-cycle if the drum is full of hot, soapy water.

Steps to resolve:

• Allow auto-correction: The machine will usually add extra rinses and pauses to clear suds. Let it complete this process.
• Run extra rinse: If suds remain, run an additional rinse and spin cycle without detergent.
• Adjust detergent use: Use only HE (high-efficiency) detergent and reduce the amount, especially in soft water areas. Follow Samsung's dosage recommendations.
• Check drain system: If SUD appears frequently, clean the drain pump filter and ensure the drain hose is not restricted.

When to stop: Persistent SUD even with minimal detergent may indicate a pressure sensor or drain issue; further diagnosis may be needed.
