FAFW3577KA (older 2008-era front load): the console board suspects the mechanism that locks the door has failed.
FAFS4272LR (front load): trouble in the PTC circuit of the door.

Because E43 depends on the model, have the model number ready when you dial (415) 319-6371. Also bring up what appeared on the display and what you did first; Frigidaire washer repair covers the rest.
Model compatibility: Frigidaire reuses codes across series and model years, so E43 may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.
