Samsung Washer Error Code FL — FlexWash Communication Error
What this means
The FL error code is specific to Samsung FlexWash models (like the WV60M9900AV) that feature a separate small washer built into the top of the main washer. This code indicates the main washer's control board and the upper washer's control board have lost communication. The upper washer may not respond or may not start cycles independently. Causes include a loose wire harness between the two units, a power supply issue, or a failed control board in either the upper or lower unit.
Alternate codes: FLO
Step-by-step fix
4 stepsPower cycle the entire unit
Unplug the washer for 5 minutes. This resets both the main washer and the upper FlexWash module. Restore power and check if both units respond.
After powering on, try starting a cycle on the upper washer independently to verify communication is restored.
Check the communication harness
Unplug the washer. The wire harness connecting the upper washer to the main unit runs internally between the two sections. Open the top panel or rear panel to access the connectors. Reseat all harness connections firmly.
Look for any pinched wires where the upper unit sits on top of the main washer body.
Test the upper washer power supply
The upper FlexWash unit may have a separate power board or receive power through the communication harness. Verify that voltage is reaching the upper unit by checking at the connector with a multimeter.
If the upper washer display is completely blank, it likely has no power — the issue is in the harness or power board.
Replace the harness or control board
If the harness has a broken wire or damaged connector, replace it. If the harness is intact and voltage is present at the upper washer board but it still does not respond, the upper washer control board may need replacement.
Samsung FlexWash control boards are model-specific — use your exact model number when ordering.
When to call a professional
FlexWash systems have complex dual-control architectures. If basic troubleshooting does not resolve the FL code, Samsung service or a certified technician should diagnose which board has failed.
