What PF (Power Failure - Resume) Means
PF means power to the washer was interrupted mid-cycle, most often from a household outage, and the washer will resume from where it left off - LG's top-load washer article is explicit this is not an error and simply requires pressing Start/Pause to continue. LG's front-load article treats the same code more cautiously, saying a repeat PF after a reset may need service, so this entry reflects both: it's usually a harmless resume notice, but a PF that won't clear is worth having checked.
Common Causes of PF (Power Failure - Resume)
- Household power outage or a tripped breaker mid-cycle
- Washer accidentally unplugged during a cycle
- Recurring PF unrelated to any actual outage may indicate a power supply fault inside the washer
🔧 One Safe Check You Can Try
Press the Start/Pause button to resume the interrupted cycle; if PF keeps reappearing on later, unrelated cycles rather than just once after an actual power interruption, that's the point to stop assuming it's harmless.
⚠ Why You Shouldn't Go Further Than That
- If PF appears repeatedly without any actual outage or unplugging event you're aware of, that pattern (rather than a single PF after a storm) is what points to an internal power-supply fault needing a technician, not a resume notice.
