LG Dishwasher Error Code PF: How to Fix It

Q: Will I lose my wash cycle progress when PF error appears?

Yes, when power is interrupted during a cycle, you'll need to restart from the beginning. Modern LG dishwashers don't have cycle memory for power failures.

Yes, it's safe to restart immediately after clearing the PF error. However, if dishes have been sitting with detergent, consider running a rinse cycle first.

Q: Why does my LG dishwasher keep showing PF error?

Frequent PF errors indicate unstable electrical power supply, loose connections, or potential control board issues. Check your home's electrical system and consult a professional if needed.

Q: Can a surge protector prevent PF errors?

A surge protector can help protect against power surges but won't prevent PF errors caused by complete power outages or circuit breaker trips.
