LG Washer (front load) Sud

LG Sud: Too many suds were detected.

LG's front load washer error code list says Sud means too many suds were detected. The washer adds a suds-reducing cycle of about two hours, and stops during spin if suds are still detected.

The checks, with LG's detail

  1. 1If you use liquid detergent, fill only to the Max line

    LG says to use HE detergent, keep the liquid cup in place and not go over the Max line.

  2. 2If you use powder, remove the liquid cup

    LG says powder left in the liquid cup can clog the inlet and cause an overflow.

  3. 3If you use pods, one pod per load, in the drum

    LG says to place a single pod directly in the drum, one per load, and never in the drawer.

  4. Does Sud still appear?

Where to stop

LG's list gives no service step for Sud and treats it as a detergent-dosing problem. Editorial boundary: if the cycle never finishes, or a different code follows, treat that as the code to look up, or contact LG support.

Not covered here, on purpose: Nothing on LG's list. This site does not add anything beyond it. Read when to stop and call a technician.
