Sd — Suds (Confirm for Your Model)

"Sd" (suds) is a common convention on washers; it is not listed in Frigidaire’s official dishwasher error-code guide, where excessive suds/foam in the leak pan is i30. If your Frigidaire dishwasher shows Sd, treat it as a suds/over-foaming condition (use only dishwasher detergent in the correct amount) and confirm against your model docs.

How to fix it

  1. Open the door, scoop out visible foam.
  2. Pour a cup of cold water into the tub to knock down suds.
  3. Run a Rinse-Only cycle with NO detergent — repeat 2-3 times until suds are gone.
  4. Verify only ADA-listed dishwasher detergent is being used.
  5. Reduce rinse aid setting one notch if foam recurs.

Why it happens

Typical signs: Sd shown with extended cycle time · Foam visible through the door vent or around the seal · Cycle progress stalls

  • Wrong detergent — hand dish soap used Hand dish soap creates massive suds. Use only dishwasher-rated detergent.
  • Too much rinse aid Rinse aid dispenser overfilled or a leaky cap.
  • Detergent residue from previous wrong load Suds linger across cycles until flushed.
  • Greasy load with hot water Heavy grease + high temp can foam, especially with the wrong detergent.
