Samsung Washer Error Code 1SUD

The 1SUD code means the washer has detected excessive foam or suds inside the upper drum. The machine automatically triggers a suds removal routine, pausing the cycle until the foam dissipates. This is most commonly caused by using too much detergent or a non-HE detergent formula. No parts replacement is needed in the majority of cases.

Yes, the washer is not in a dangerous condition when this code appears. The machine is designed to handle excessive suds by running a built-in removal routine before continuing. You should not force-open the lid or interrupt the cycle mid-process, as the drum may still contain a large volume of foam and water.

In most cases there is no repair cost at all, since the issue is resolved by adjusting detergent type and quantity. If a faulty sensor is identified as the cause after ruling out detergent problems and drainage issues, repair costs including parts and labor could range from roughly $100 to $250 depending on your location and service provider.

Start by allowing the washer to complete its automatic foam reduction cycle without interruption. Once the cycle finishes, reduce the amount of detergent you use and confirm the detergent is HE-rated. If the drum or dispenser has visible residue buildup, run a drum-clean cycle and rinse the dispenser tray thoroughly. Adjust your detergent dosage going forward based on your load size and water hardness.

A manual reset may clear the code temporarily, but it will not address the underlying cause. If excess suds are still present in the drum, the code is likely to return as soon as the next cycle begins. It is better to let the automatic suds cycle complete and then correct your detergent usage before running another load.
