Asko range display shows PF and clock is flashing after a power interruption.

Safety first: Confirm that power is stable and that no breakers are tripped.

• Clear code: Press any key or the "Cancel"/"Off" button to clear PF. Reset the clock and any programmed settings.
• Check connections: If PF appears frequently without known outages, inspect the range’s terminal block and household wiring for loose connections (have an electrician do this if you are not qualified).
• Monitor: If PF recurs, log the times and conditions; this can help an electrician or technician diagnose supply issues.

PF itself is not a fault in the appliance but a symptom of unstable power.
