Samsung washer FL error: main door is not detected as locked

Samsung includes FL in its normal washer door-error group, meaning the main door is not detected as closed and locked. This differs from dC3/ddC, which Samsung reserves for the Add Door on models that have the smaller secondary opening.

Model check required. Samsung groups FL with main-door errors across supported washer families. Exact latch and lock hardware varies by model, so use the full model number before replacing parts.

Can the washer confirm the main door is closed and locked?

FL clears after removing trapped laundry

The main door was not seating completely. Keep garments away from the seal and latch area on future loads.

The main door is closed but FL remains

The latch, lock feedback, alignment, wiring, or control may need service diagnosis. Do not repeatedly force the handle.

The code is dC3 on an Add Door model

Use the dC3 guide instead; Samsung defines that code specifically for the secondary Add Door.
