LG Washing Machine Error PF: Power Failure During Cycle

Clear meaning, realistic next steps, and safe guidance without turning the page into a long repair manual.

What it means

The washer detected a power interruption during an active cycle. This is an informational code — it tells you the cycle did not complete normally due to lost power. The machine has paused and is waiting for your input.

Severity

Low - usually safe to check with basic user-accessible cleaning or inspection on the LG washing machine.

Can you fix it yourself?

Yes — DIY-safe

Most likely cause

Brief power outage or brownout while the washer was running

Estimated time for safe first checks: 2–5 min — reset and restart.

Step-by-Step DIY Fix Guide

  1. SAFETY: No electrical hazard — PF is an informational status code.
  2. Check that the washer is still plugged in and the power cord is secure.
  3. Check the circuit breaker for the washer circuit — reset it if it has tripped.
  4. Check any GFCI outlet the washer is plugged into and press the reset button if the outlet has tripped.
  5. Press Power on the washer to acknowledge the PF code.
  6. Restart the cycle from the beginning — LG washers do not resume mid-cycle after a power failure.

If the code comes back

  • Circuit breaker trips every time the washer runs — circuit capacity issue requiring an electrician

What This Error Means

Error PF on your LG washing machine means: The washer detected a power interruption during an active cycle. This is an informational code — it tells you the cycle did not complete normally due to lost power. The machine has paused and is waiting for your input. The washer's self-diagnostic system has detected this condition and paused the current cycle.

The most frequent cause is brief power outage or brownout while the washer was running. Work through the causes and fix steps below in order — most LG washer errors are resolved without a service call.

Error PF is DIY-safe. No tools are required and the fix typically takes under 15 minutes. Follow all steps in sequence.

A power failure mid-cycle is not a hardware fault. Once power is restored, press Power to acknowledge the code and restart the cycle from the beginning. If the circuit breaker tripped, investigate the cause before restarting.

Most Likely Cause by Symptom

The LG washing machine may stop, pause, or refuse to complete the cycle normally.

Likely cause: Brief power outage or brownout while the washer was running

Check first: SAFETY: No electrical hazard — PF is an informational status code.

Common Causes

  • Brief power outage or brownout while the washer was running
  • Circuit breaker for the washer circuit tripped during the cycle
  • Power cord accidentally pulled or outlet power interrupted
  • Power surge that caused the GFCI outlet to trip

What Not to Do

  • Do not ignore a circuit breaker that repeatedly trips on the washer circuit — it indicates an electrical problem that needs to be corrected

Model and Display Variation Notes

Model-family notes

  • LG washing machine display wording and code formats can vary by series.
  • If your model behaves differently, check the owner manual before trying any deeper maintenance step.

Display and panel differences

  • Panel wording can vary by series, so confirm the exact code pattern before buying parts.

Parts, Tools and Service Options

Manual and model check

Check your exact model and manual before ordering any LG washing machine parts.

This section stays model-first because exact manual and parts matching matters more than a generic replacement suggestion here.

When Not to Keep Troubleshooting

Circuit breaker trips every time the washer runs — circuit capacity issue requiring an electrician

How to Prevent It Recurring

  • Plug the washer into a dedicated circuit — sharing a circuit with other high-draw appliances can cause the breaker to trip
  • Consider a whole-home surge protector to protect the washer's electronics from voltage spikes during power restoration
