Error Code: SUD Difficulty: Easy
Problem: Excess suds detected – non-HE detergent or overdosing causing foam buildup
How to Fix SUD Error
- Cancel current cycle and select Rinse+Spin cycle without detergent 2-3 times to remove suds.
- Use only HE (High Efficiency) detergent labeled specifically for front-load washers.
- Reduce detergent amount to 1-2 tablespoons (15-30ml) for standard loads; 1 tablespoon for soft water areas.
- Avoid liquid fabric softener – use dryer sheets instead (softener coats drum causing suds retention).
- Clean detergent dispenser drawer thoroughly with warm water and old toothbrush to remove residue buildup.
- Run Tub Clean cycle monthly with affresh tablet or 1 cup white vinegar to remove soap scum buildup.
- Check water hardness – soft water requires less detergent than hard water (use water test strip to determine dosage).
Samsung Washer SUD Checks Before Replacing Parts
- Restart the washer and confirm the SUD message returns under the same condition instead of after a one-time interruption.
- Check the simple causes first: load balance, water supply, drain flow, door or lid closure, visible leaks, and power stability.
- Inspect accessible wiring connectors and moisture-prone areas before assuming the control board has failed.
- Use the complete Samsung washer model number from the door, lid, or rear tag before matching any pump, valve, sensor, suspension, lock, or board category.
- If the SUD code points to a specific system, test that system directly before ordering replacement parts.

If the replacement part didn’t fix the issue, you may have a wiring problem or main board failure.
