ApplianceWasher
Quick answer
SUd and its variants mean the washer detected too many suds. It pauses briefly and then resumes, and no service is needed.
Model compatibility: Samsung reuses codes across series and model years, so SUd, 5UD, Sd, 5d, SUdS, 5Ud5 may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.
Plain language
What this code means
Excessive suds detected; the washer pauses briefly, then resumes. Not a fault.
SUd tells you the washer has detected an over-sudsing condition. It can also display as 5UD, Sd, 5d, SUdS or 5Ud5. The washer stops for a short period so the suds can dissipate, and the cycle then continues by itself. The code may flash again at the end of the cycle as a reminder.
It is not a fault
Samsung says this code does not indicate that service is needed. It comes from incorrect use of detergent, so the useful step is to review how much detergent goes in and whether it is the right kind.
If the code keeps appearing
Check that the supply hoses and the drain hose behind the washer are not kinked.
Run an empty cycle with no additives, such as detergent or fabric softener, and watch for suds.
If suds appear, too much detergent or a non-HE detergent has been used. Keep running empty cycles until the suds are gone, then see whether the code returns.
If no suds appear but the code continues, visit Samsung’s Support Center to request service.

Important safety warning. Do not attempt repairs involving electrical components, gas, water lines, refrigerant or sealed systems. Unplug the appliance if it is safe to reach the outlet, and leave internal diagnostics to a qualified technician.
