LG Washer · Code Sud / SUD

LG Washer Sud code: Too many suds

The washer found too much foam in the tub and paused to break it down. This slows the cycle and can lead to drain problems.

Most common causes

  1. Using non-HE detergent
  2. Using too much detergent
  3. Soft water, which makes detergent foam more
  4. Detergent residue building up in the tub

What you can safely check yourself

  1. Use only HE detergent and measure to the line for the load size
  2. Run a Rinse+Spin with no detergent to clear the foam
  3. Run the Tub Clean cycle to remove residue

Unplug the appliance before moving or cleaning anything. Do not open panels, touch gas connections or bypass safety switches.
