Answer to continue safely
Is it safe to keep using?
Maybe. The washer is safe to restart once stable power is confirmed. Do not run another cycle until you have verified the outlet voltage and that the breaker holds — repeated incomplete cycles can stress the motor.
Can I reset the code?
Yes. Press Start/Pause to dismiss the PF alert, then re-select and start a new cycle. No special reset procedure is required beyond restoring stable power.
When to stop immediately?
Stop if you notice: Stop using the washer if the PF code appears on every cycle despite verified stable household power., Stop if the circuit breaker trips repeatedly when the washer runs, indicating a possible wiring or motor fault..
Symptoms You May Notice
Washer stops mid-cycle with wet laundry inside
The drum halts completely during a wash or spin cycle, leaving clothes soaking wet and unsatisfactory rinsed.
PF code displayed on control panel
After power is restored, the display shows PF instead of continuing the interrupted cycle.
Water remains in the drum after stoppage
Because the drain spin was not completed, standing water may be visible inside the drum when the lid or door is opened.
Cycle timer resets or loses its position
The washer cannot resume from the exact point of interruption; it returns to the beginning of the cycle selection screen.
Possible Causes
Household power outage or brownout
A temporary loss of utility power during the cycle is the single most common cause of a PF code.
DIY PossibleTripped circuit breaker or blown fuse
An overloaded circuit supplying the washer outlet can trip the breaker, cutting power unexpectedly.
DIY PossibleFaulty main control board power circuit
Internal power-regulation components on the PCB can fail and generate a false PF signal even when wall voltage is normal.
Requires ProfessionalSafe Checks You Can Do
-
1
Check the circuit breaker panel
Locate the breaker dedicated to the laundry circuit and confirm it is fully in the ON position. Reset it by flipping to OFF then back to ON if it has tripped.
-
2
Inspect the power cord and outlet
Ensure the cord is firmly plugged in and the outlet delivers correct voltage using a multimeter or outlet tester. Avoid using an extension cord.

Press Start/Pause to clear the code and restart
Once power is stable, press Start/Pause to acknowledge the PF code. Select the desired cycle and restart. If the load is still wet, run a full cycle from the beginning.
When to Call a Professional
Contact a qualified technician if:
- PF code recurs on a dedicated circuit with confirmed stable 120 V supply — suggests internal PCB fault.
- Breaker trips every time the washer enters the spin cycle — possible motor winding or capacitor failure.
- Visible burn marks on the power cord plug or wall outlet — requires licensed electrician before appliance service.
