Sd / SUD

Sd or SUD on display - Excessive suds

Whirlpool · Washing Machines

What does Sd / SUD mean?

The washer has detected too many suds and is running a suds reduction routine. This indicates an imbalance in detergent use or type.

Common Causes

  • Not using HE (High Efficiency) detergent.
  • Using too much HE detergent for the load size or soil level.
  • Using natural, organic, or homemade HE detergents that may generate higher suds levels.

  3. 3

    Always measure detergent carefully and follow the manufacturer's instructions based on load size and soil level.

    If using natural, organic, or homemade HE detergents and the issue persists, consider trying a different HE detergent brand.
