Answer to continue safely
Is it safe to keep using?
Yes. PF is an informational code only. The dryer has no fault — simply clear the code and restart the cycle. The appliance is completely safe to use.
Can I reset the code?
Yes. Press any button to clear the PF notification, then select a cycle and press Start. No further reset action is needed.
When to stop immediately?
Stop if you notice: PF appears every cycle with no known power outages, suggesting the circuit breaker is repeatedly tripping — investigate before continuing use., The circuit breaker trips again immediately after being reset, indicating a possible short circuit in the dryer or home wiring..
Symptoms You May Notice
Dryer is off and unresponsive when you return
A power interruption cuts the dryer mid-cycle; when power is restored the machine powers back up but does not resume automatically, leaving clothes still damp inside.
PF displayed immediately when dryer regains power
The control panel shows PF as the first thing displayed after the dryer is powered back on, alerting the user that the previous cycle was interrupted.
Clothes still wet after the cycle appeared to have run
Because the cycle was cut short by the power loss, clothes did not complete the drying process and need the cycle restarted to fully dry.
Circuit breaker in the OFF or tripped position
Finding the dryer's circuit breaker tripped confirms a power interruption rather than a dryer malfunction as the cause of the PF code.
Possible Causes
Home power outage
A utility power interruption, even one lasting only a few seconds, is enough to cut the dryer cycle and generate the PF code when power is restored.
DIY PossibleTripped circuit breaker
An overloaded circuit or an intermittent fault trips the dryer's breaker, cutting power mid-cycle in exactly the same way as a power outage.
DIY PossibleDryer unplugged accidentally or power cord kicked loose
A power cord that is not fully inserted into the outlet or was accidentally kicked loose loses contact mid-cycle, triggering the power failure detection.
DIY PossibleSafe Checks You Can Do
-
1
Acknowledge and clear the PF code
Press any button on the control panel (usually the Power or Start button) to acknowledge the PF notification. The code will clear and the dryer will be ready to accept a new cycle selection.
-
2
Check the circuit breaker
If PF appeared unexpectedly, check your electrical panel. If the dryer's double-pole breaker is in the tripped position, flip it fully OFF then fully ON to reset it before restarting the dryer.
-
3
Restart the drying cycle
Select the appropriate cycle for the load still in the drum and press Start. The dryer will operate normally — PF does not indicate any dryer component damage.
When to Call a Professional
Contact a qualified technician if:
- The dryer's circuit breaker trips repeatedly under normal loads, indicating a wiring or component fault drawing excess current.
- PF is accompanied by other error codes after power restoration, suggesting the power interruption caused a secondary component fault.
- The outlet or power cord shows physical damage consistent with arcing or overheating.
