LG Washer Error Code Sud: How to Fix It

Q: Why does my LG washer keep showing the Sud error?

The Sud error typically occurs from using too much detergent, using regular detergent instead of HE detergent, or detergent buildup in the machine. Make sure you're using only 1-2 tablespoons of HE detergent per load.

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

No, you should only use HE (High Efficiency) detergent in LG washers. Regular detergent creates too many suds and can trigger the Sud error code while potentially damaging your washer.

Q: How long does it take for the Sud error to clear?

The Sud error usually clears after running 1-2 rinse and spin cycles. In severe cases with excessive suds, it may take 20-30 minutes of waiting plus additional rinse cycles.

Q: Is the Sud error dangerous for my LG washer?

The Sud error is not dangerous - it's a protective feature. However, repeatedly ignoring proper detergent usage can lead to buildup that may damage internal components over time.

Q: What's the difference between Sud and Suds error codes?

Sud and Suds are the same error on LG washers - both indicate excessive suds detection. Some models display 'Sud' while others show 'Suds' but the meaning and solution are identical.

Abstract

The Sud error code on your LG washer indicates that excessive suds have been detected in the wash drum. This typically occurs when too much detergent has been used or the wrong type of detergent is being used in your high-efficiency washer.
