Diagnostic overview for error SUD
Use the sequence meaning → symptoms → accessible checks → stop conditions. For SUD, the current manufacturer-sourced summary is: Samsung states that the washer pauses to let excess suds dissipate and that the code normally reflects incorrect detergent use rather than a service fault.
Safe sequence
- 1Allow the washer to complete its automatic suds-reduction pause.
- 2Use only the detergent type specified in the model manual.
- 3Reduce the dose for concentrated detergent and future small loads.
Stop and get qualified help when
- Foam or water leaks from the appliance
- The code persists with correct detergent and dosage
