Frigidaire Dishwasher Sd — Excessive suds detected

Frigidaire Dishwasher · Error code Sd

What Sd Means

The dishwasher detects excessive foam in the tub. The control board pauses the cycle and may run extra drain/rinse to flush suds before continuing.

Symptoms

  • Sd shown with extended cycle time
  • Foam visible through the door vent or around the seal
  • Cycle progress stalls

Common Causes

1
Wrong detergent — hand dish soap used

Hand dish soap creates massive suds. Use only dishwasher-rated detergent.

2
Too much rinse aid

Rinse aid dispenser overfilled or a leaky cap.

3
Detergent residue from previous wrong load

Suds linger across cycles until flushed.

4
Greasy load with hot water

Heavy grease + high temp can foam, especially with the wrong detergent.

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.
