How to fix it

  1. Wait — the washer will run a suds-reduction routine automatically.

  3. Switch to HE detergent and use only 1-2 Tbsp per load.
  4. Add a monthly Affresh tablet to control residue.

Why it happens

Typical signs: Sd or SUDS code · Visible foam in the tub · Cycle takes much longer than usual

  • Non-HE detergent used Conventional detergent produces too much foam in HE washers.
  • Overdose of HE detergent Even HE detergent creates suds if overused.
  • Detergent buildup in tub Residue from past loads re-foams.
  • Soft water area Soft water amplifies sudsing — use even less detergent.
