LG Washing Machine (Combo) SUD error code

Difficulty: Easy · Cost: $0 · Duration: No action needed — cycle resumes automatically

The SUD error on your LG washer dryer combo means too many suds were detected inside the drum. The unit automatically adds a suds-reducing cycle which can add up to 2 hours to the total cycle time. If too many suds are detected during spinning the unit stops to prevent leaking. Always use HE high-efficiency detergent and follow the manufacturer's recommended dosage.

Common causes

Too much detergent was used
Non-HE detergent was used in a high-efficiency unit
Powder detergent was added to the liquid detergent cup causing incorrect dispensing

How to fix it

1

Wait for the unit to complete the automatic suds-reducing cycle — do not interrupt it
2

Do not add more detergent
3

After the cycle switch to HE detergent and use only the manufacturer's recommended amount
4

Do not add powder detergent to the liquid detergent compartment
