Answer to continue safely
Is it safe to keep using?
Yes. PF is a notification, not a fault. Once acknowledged with a button press, the cooktop is fully operational. Verify all burner settings before resuming cooking.
Can I reset the code?
Yes. Pressing any button on the control panel clears the PF code immediately. No breaker reset or repair is needed for a routine power failure notification.
When to stop immediately?
Stop if you notice: PF is accompanied by any error code such as F1, F3, or F4., The circuit breaker trips repeatedly after each reset..
Symptoms You May Notice
PF displays on power restoration
The control panel shows PF immediately when power returns after an outage or breaker trip — the most common and expected presentation of this code.
Clock or timer settings are lost
Any timer countdowns or clock settings stored in volatile memory are cleared by the power interruption, consistent with the PF notification.
All burners are off when PF appears
The cooktop resets all burner outputs to off on power restoration as a safety measure, regardless of their state before the outage.
PF clears with any button press
Pressing any control pad button or knob acknowledges the PF notification and returns the cooktop to normal standby mode.
Possible Causes
Home power outage or brownout
Utility supply interruptions are the most common cause of PF. The code is a normal response to any power gap, not a sign of cooktop failure.
DIY PossibleTripped circuit breaker
An overloaded or nuisance-tripping circuit breaker for the cooktop circuit causes PF whenever it trips and is reset. A repeatedly tripping breaker should be investigated by an electrician.
DIY PossibleSafe Checks You Can Do
-
1
Acknowledge and clear the PF code
Press any button on the control panel to clear the PF notification. The cooktop will return to normal standby. No other action is required for a routine power outage.
PF is informational only. It requires no repair and does not indicate any component has failed.
-
2
Check for a tripped breaker
If PF appeared without a known utility outage, check the home electrical panel for a tripped breaker on the cooktop circuit. Reset it once. If it trips again, contact an electrician — do not repeatedly reset a breaker that keeps tripping.
A cooktop circuit that trips frequently may be undersized or have a wiring fault unrelated to the appliance.

3
Verify burner settings after clearing PF
After clearing PF, confirm that all burner knobs are in the off position before resuming cooking. The power interruption resets all outputs to off, but physical knob positions should also be verified.
If a burner was left on before the outage, the cooktop will not restart it automatically — you must manually relight.
When to Call a Professional
Contact a qualified technician if:
- The circuit breaker for the cooktop trips more than once without explanation.
- PF appears together with another fault code on the same power-up.
- The control panel does not clear PF after any button press is attempted.
