Dryer displays E19 and may not start; this is sometimes associated with the child lock or safety interlocks.

Safety first: Ensure the dryer is stable and not accessible to children while troubleshooting.

• Disable child lock: Follow the user manual to turn off the child lock (often by holding specific buttons for several seconds). See if E19 clears.
• Power reset: Unplug the dryer for 5–10 minutes, then reconnect.
• Check control buttons: Ensure the lock-related buttons are not stuck or damaged.
• If E19 remains, the safety interlock circuit on the main PCB or UI board may be faulty. Replacement of the affected board is recommended via a qualified technician.
