Asko Microwave PF Error: Power failure indicator
Asko microwave PF error is a common issue reported by Asko appliance owners. What PF Means on an Asko Microwave PF stands for Power Failure. Asko microwaves display this code when the appliance detects that mains power was interrupted and subsequently restored. This is an informational alert rather than a fault code — it tells […]

Answer to continue safely
Is it safe to keep using?
Yes. Once the PF code is cleared and the clock is reset, the microwave is safe to use normally. PF is an informational alert, not a fault. If PF recurs frequently, investigate the power supply.
Can I reset the code?
Yes. Pressing STOP/CLEAR dismisses the PF code immediately. A 60-second power-cycle is not necessary for PF — simply clear the code and reset the clock.
When to stop immediately?
Stop if you notice: PF code recurs multiple times per day with no known power interruptions — supply fault suspected., PF is accompanied by any other fault code, sparking, or burning smell after power restoration..
Symptoms You May Notice
PF displayed on screen after power is restored
The letters "PF" appear on the microwave display immediately after the power comes back on following an outage or breaker trip.
Clock reset to 0:00 or blinking
The clock display is reset or blinking, confirming a power interruption caused the control board to lose its time setting.
All programmed settings cleared
Any custom cook programmes or saved settings have been erased, which is normal behaviour after a power failure event.
PF appears repeatedly without a known outage
Recurring PF codes when no outage has occurred suggest voltage instability on the supply circuit or a loose power connection.
Possible Causes
Mains power interruption
Any interruption to the household supply — outage, circuit trip, surge, or brownout — causes the microwave to display PF on restoration.
DIY PossibleLoose power cord or wall socket connection
An intermittent connection at the plug or socket causes repeated micro-interruptions that each trigger a PF code.
DIY PossibleVoltage instability on the kitchen circuit
Shared circuits with high-draw appliances (dishwasher, kettle) can cause brief voltage dips that reset sensitive electronics.
Requires ProfessionalSafe Checks You Can Do
-
1
Clear the PF code and reset the clock
Press STOP/CLEAR once to dismiss the PF alert. Then press CLOCK, enter the current time using the number pad, and press CLOCK again to confirm.
The microwave is fully operational immediately after clearing PF — no further steps are needed if this is a one-off event.
-
2
Check the power plug and socket
Unplug the microwave and re-seat the plug firmly in the socket. Check the socket with another appliance to confirm a stable connection. Examine the power cord for kinks near the plug.
Microwaves draw significant current at start-up — a loose plug can cause a momentary voltage drop sufficient to reset the board.

3
Run a test cycle
Place a cup of water in the cavity and run a 1-minute full-power cycle. Confirm the water heats, the turntable rotates, and no error codes appear.
If the microwave passes the test cycle without issues, it is operating normally — PF was informational only.
When to Call a Professional
Contact a qualified technician if:
- PF appears frequently (more than once per week) without known outages, indicating supply instability.
- Microwave does not heat correctly after clearing PF, suggesting the power event caused component damage.
- Circuit breaker trips each time the microwave is used after a PF event.
