PF shows up after the dryer’s power was interrupted mid-cycle, usually a blackout or a tripped breaker. It’s a memory flag, not a diagnosis: the control board is telling you the cycle didn’t finish, nothing more.

Whirlpool Dryer Error Code PF (Power Failure Memory)
PF just means the dryer lost power mid-cycle and remembers it, it’s not a sign of a broken part.
Meaning
Possible causes
No cause is certain until it has been checked on the appliance.
- Very likely Recent power outage or breaker trip
- Likely Dryer unplugged or moved while running
- Possible Loose power cord connection at the outlet
- Rare Recurring internal electrical fault on the control board
First checks
- Press Start once to clear the code and resume or restart the cycle.
- Check the breaker panel for the dryer circuit and reset it if tripped.
- Push the power cord fully into the outlet and confirm the outlet isn't loose.
- Note whether PF keeps returning on every cycle, not just after a known outage.
What not to do
- Assuming PF means a part failed and ordering replacement parts before checking for a simple power interruption.
- Repeatedly restarting the cycle without checking the breaker if PF returns every time.
An error code varies by brand
The same code can have a different meaning depending on the brand and model. Always check your appliance's manual before acting.
