Samsung Washing Machine Error Code SUd: Excessive suds
Applies to Samsung washing machines that show SUd or Sd, 5d, SUdS on the display.
The washer has detected too many suds and pauses to let them dissipate. It is caused by the wrong detergent or too much of it — no service is needed.
What this code means
Over-sudsing stops the cycle for a short period while the foam breaks down; the cycle then continues automatically, though the code may flash again at the end as a reminder.
The manufacturer's checks, in order
- Let the washer finish its suds-clearing pause — the cycle resumes on its own.
- Next wash, use HE detergent in an HE washer and reduce the dose.
