SUD or SUDS code = Excessive soap in washer drum

What Is The Samsung Washer SUD Error Code?

The SUD code simply means there are too many soap suds in the drum. Too much detergent or the wrong type of detergent was used. Basically, too much foam in the washer for it to run correctly. The washer will wait until it senses the suds have been reduced and then resume the wash cycle. This is sensed by a foaming control feature or foam level sensor.

What Can Cause The SUD Error Code?

– The detergent you are using is not made for HE washing machines. (wrong soap)
– You are using a larger excessive amount of detergent. (too much soap)
– The soap or detergent used is not a quality detergent. (no dollar store soaps)
– Non “HE” detergent usually has high sudsing properties and will cause excessive amounts of suds. (high sudsing)
– The washer foam level sensor has failed and showing the SUD error. (component failure)
– There is a clog in the lines or drain and causing the SUD code. (clogged lines)

How To Fix or Reset The SUD Error Code?

– Give the washer some time to let the SUDS reduce. Once reduced, the washer will continue washing.
– Run the washer empty and program a longer wash cycle with the hottest water temp setting to remove the SUDS.
– Be sure to follow the detergent manufacturer’s suggested amount of detergent.
– Switch to an approved HE washing machine detergent that works with your washer.
– Use a high efficiency cleaning detergent with low sudsing properties.

What If The SUD Code Still Displays?
