Samsung Washer Error Code SUd: How to Fix It

Q: Why does my Samsung washer keep showing SUd error even with HE detergent?

If you're using the correct HE detergent and amount but still get SUd errors, you may have detergent buildup from previous overuse, or the pressure sensor could be malfunctioning. Run multiple rinse cycles and a cleaning cycle to remove residue, then test again.

Q: Can I use regular detergent in my Samsung HE washer?

No, you should only use HE (High Efficiency) detergent in Samsung HE washers. Regular detergent creates too many suds and will trigger the SUd error. HE detergent is specially formulated for low-water, high-efficiency machines.

Q: How much HE detergent should I use in my Samsung washer?

Use only 1-2 tablespoons of HE liquid detergent for a normal load. For heavily soiled items, don't exceed 3 tablespoons. Using more detergent doesn't clean better and will cause the SUd error.

Q: Will the SUd error damage my Samsung washer?

The SUd error itself won't damage your washer - it's a protective feature. However, consistently using too much detergent can cause buildup that affects performance and may lead to drainage issues or component wear over time.

Q: How long does it take for Samsung washer to clear SUd error?

The automatic foam removal cycle typically takes 5-15 minutes. In severe cases with excessive suds, it may take longer or require manual intervention with additional rinse cycles to completely clear the error.

Abstract

The Samsung washer SUd error code (also displayed as 5UD, Sd, 5d, or SUdS) appears when your washing machine detects too many soap suds in the drum. This usually happens when you use too much detergent, the wrong type of detergent, or regular detergent instead of high-efficiency (HE) detergent.
