Asko Washer F9 Error: Programme memory fault
Asko washer F9 error is a common issue reported by Asko appliance owners. What Asko Error Code F9 Means Error code F9 on Asko washing machines points to a programme memory or software fault on the main control board. The control board’s EEPROM or flash memory has encountered a read or execution error, making the […]

Answer to continue safely
Is it safe to keep using?
No. A programme memory fault makes the machine's behaviour unpredictable. It may stop at any point mid-cycle. Do not use the machine until the control board has been inspected.
Can I reset the code?
Yes. A factory reset procedure may clear a transient memory corruption. However, if the EEPROM chip or firmware is permanently corrupted, the fault will return immediately.
When to stop immediately?
Stop if you notice: The machine fails the power-on self-test and shuts down immediately every time., Display shows scrambled or garbled characters that do not clear after a factory reset..
Symptoms You May Notice
Machine aborts at a completely different point each time
Unlike most fault codes that appear at a consistent moment, F9 can appear at random points — mid-fill, during wash, or at spin — because the memory corruption affects different programme steps each time.
Display shows unusual characters or scrambled segments
The programme display shows garbled text, random segment illumination, or characters that do not correspond to any valid setting, indicating corrupted memory content.
Previously selected settings are forgotten between cycles
Temperature, spin speed, and programme preferences set by the user are not retained between sessions — the machine resets to default settings each time it is powered on.
Machine powers on then immediately shuts down without user input
On powering up the machine the display briefly illuminates, then goes dark and the machine shuts off, as the control board detects the memory fault during its power-on self-test.
Possible Causes
Power surge corrupting EEPROM memory
A sudden mains power spike during an active cycle can corrupt the EEPROM non-volatile memory chip on the control board, scrambling programme data.
DIY PossibleFailed EEPROM or flash memory chip on PCB
The memory chip on the control board can fail due to age, thermal stress, or manufacturing defect, permanently corrupting the stored programme data.
Requires ProfessionalFirmware corruption after an interrupted update
On Asko models with user-accessible firmware update capability, an interrupted update can leave the control board in a partially-flashed state that generates F9 on every startup.
Requires ProfessionalSafe Checks You Can Do
-
1
Perform a factory reset
Unplug the machine. Hold down the Start button while reconnecting the mains power, keeping Start held for 5 seconds after power is restored, then release. The display should briefly show all segments illuminated before returning to the default programme. The exact reset procedure varies by model — consult the Asko owner manual for your specific model code.
On some Asko Logic series models the factory reset is performed by holding both the Temperature and Spin buttons simultaneously while powering on.

2
Plug into a different mains socket
After the factory reset attempt, plug the machine into a different mains socket — ideally on a different circuit — to rule out ongoing power quality issues. Run a 30-minute test cycle and observe whether F9 recurs.
Consider fitting a surge-protected extension lead if your home experiences frequent power fluctuations — this protects the control board from future corruption events.

3
Document the fault and call Asko service
Note the full model number (on the label inside the door rim), the serial number, and the exact behaviour — when F9 appears in the cycle, any unusual display behaviour, and whether the machine retains settings between power cycles. This information speeds up diagnosis significantly.
Asko's service team can sometimes reflash the control board firmware remotely in service mode, avoiding the cost of a full board replacement.
When to Call a Professional
Contact a qualified technician if:
- Factory reset procedure has no effect — EEPROM or control board requires specialist replacement or reprogramming.
- Control board replacement for Asko W6000 series starts from $280 including firmware programming.
- Some authorised Asko service agents offer chip-level EEPROM repair for $80–120, avoiding a full board replacement.
