What Does Error PF Mean?
The LG dryer PF error code indicates a power failure or interruption detected by the appliance. This often results in the dryer unexpectedly stopping mid-cycle, with the display flashing or turning off. The PF code can appear immediately after a power fluctuation, and it suggests issues like power outages, voltage irregularities, or loose connections.
Common Symptoms:
- PF appears on display instead of a numeric code
- Dryer stops or won’t start after a power interruption or fluctuation
- Code appears immediately upon powering the dryer back on
Possible Causes
- Power outage / interruption (temporary loss of electrical supply) (medium)
- Voltage irregularity (supply voltage too high or too low) (medium)
- Loose power cord or outlet connection (low)
How to Fix Error PF
DIY Fix Check and stabilize power supply
- Turn off and unplug the dryer from the wall outlet.
