Urgency
Medium
Quick answer
PF means the washer detected an interruption or failure of its electrical supply. Confirm the household supply before restarting once.
Safety first
Stop and check this first
- Do not use extension leads, bypass a breaker or reconnect a damaged plug. Stop if there is heat, arcing, burning odour or repeated power loss.
Safe checks you can perform
- Check whether other circuits lost power
- Inspect only visible external damage
- Restart once after stable power returns
Leave these tasks to a qualified professional
- Do not attempt this professional task: Separate appliance and household supply faults
What a technician must be able to justify
Technician visit
These are the steps they must carry out and show you. Tick them as they work: if steps are skipped, do not accept a part swap.
These are not instructions for opening or handling the equipment yourself. They are the checks that should support a technical conclusion.
Separate appliance and household supply faults
What they doA qualified electrician or appliance technician should test the dedicated circuit, outlet, cord and washer power input as appropriate.
Before accepting a part or repair
Nothing has been shown yet. Do not accept a part swap based on the code alone.
Follow these steps
Note: Follow the documented order. An error code identifies the affected system, but it does not prove by itself which part has failed.
Check whether other circuits lost power
Confirm whether the interruption affected the home and whether the dedicated breaker is in its normal position.
Do not use extension leads, bypass a breaker or reconnect a damaged plug. Stop if there is heat, arcing, burning odour or repeated power loss.

Inspect only visible external damage
With power off, look for a damaged plug, cord or outlet without removing covers or touching exposed conductors.
Do not use extension leads, bypass a breaker or reconnect a damaged plug. Stop if there is heat, arcing, burning odour or repeated power loss.

Restart once after stable power returns
Use the documented resume or start control once. Stop if PF returns or the breaker opens.
Do not use extension leads, bypass a breaker or reconnect a damaged plug. Stop if there is heat, arcing, burning odour or repeated power loss.

What it means
PF records a power-failure event rather than identifying a washer component. An outage, loose plug, tripped circuit or unstable supply can interrupt the cycle; repeated PF needs electrical diagnosis.
