PF — Power failure mid-cycle
The washer lost power during a cycle. PF tells you the unit remembers what it was doing and is ready to resume — it is not a hardware fault unless it keeps coming back.

How to fix it
- Press Start/Pause to resume the cycle once power is back.
- If it won't resume, unplug the washer for 1 minute, then press and hold Start/Pause for 5 seconds while unplugged.
- Plug back in and start a fresh cycle.
- If PF returns repeatedly, plug a known-good appliance into the same outlet to test it.
- Check the breaker — reset if tripped; if it trips again, call an electrician.
- Inspect the washer's power cord at the back terminal block for scorching or loose lugs.
- Repeated PF on a confirmed-good outlet points to a failing main control board — call for service.
