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.
