Possible Causes
Door not fully latched, Faulty door switch, Control lock (child lock) enabled, Defective Start button or UI board
How to Fix / Troubleshooting
Safety: Disconnect power before accessing door latch or control panel.
- Confirm door closure: Push firmly on the door and try starting again. Listen for the latch click.
- Check for child lock: Look for a lock icon on the display. Disable the control lock per the user manual (often by holding a specific button for 3 seconds).
- Test door switch: If the unit beeps as if the door is open, test the door latch switch with a multimeter and replace if faulty.
- Inspect Start button: Remove the inner door panel and check the UI board. If the Start button pad is damaged or the board is unresponsive, replace the Samsung control panel assembly.
