Washer-dryer combo displays PF; cycle stops unexpectedly, often after a power interruption.

Safety first: Ensure hands are dry when working with electrical outlets.

• 1. Check household power:
  • Verify that other devices on the same circuit are working.
  • Reset the circuit breaker if tripped.
• 2. Inspect power cord and outlet:
  • Ensure the LG combo's plug is fully inserted.
  • Test the outlet with another appliance or a tester.
• 3. Restart cycle:
  • Press Power, then select and start the desired cycle.
• 4. Persistent PF errors:
  • If PF appears without actual power loss, the main PCB power supply may be unstable; professional diagnosis and board replacement may be required.
