What to do now
Check that the washer has stable power before restarting or clearing the display.
The wash cycle was interrupted by a power failure. Check that the washer has stable power before restarting or clearing the display. Do not keep running the appliance if the code returns or a safety sign appears.
Region: United States. This page does not generalize the code to every Whirlpool washer.
The washer recorded that the cycle was interrupted by a power failure. Whirlpool lists START held to restart the cycle, or POWER pressed to clear the display.
Confirmed: Whirlpool documents PF for top-load HE washers as a power-failure interruption during the wash cycle. This page does not treat PF as proof of a failed control board or electrical part.
Check that the washer has stable power before restarting or clearing the display.
Only after safe supply checks and only if the code clears.
Stop using the washer if power trips again, the outlet is wet, there is a hot smell, lights flicker severely, or PF repeats without a known outage.
Contact service or an electrician if PF repeats with stable household power or any electrical safety concern is present.
Whirlpool says to touch and hold START to restart the washer cycle, or press POWER to clear the display.
Use the documented action once after confirming the power area is safe. If PF returns without an obvious outage, stop repeating cycles.
Record the model label, whether there was a known outage, breaker behavior, outlet condition, and whether PF appears at startup or mid-cycle.
