Asko Refrigerator E8 Error: Control board comm error
Asko refrigerator E8 error is a common issue reported by Asko appliance owners. What Asko Refrigerator Error Code E8 Means Error code E8 on an Asko refrigerator signals a communication failure between the main control board and one of its secondary boards — typically the user interface/display board or an auxiliary module such as the […]

Answer to continue safely
Is it safe to keep using?
Maybe. The appliance may continue to cool in a default mode, but without reliable board communication, temperature management is not guaranteed. Monitor food temperatures and arrange repair within 48 hours.
Can I reset the code?
No. E8 requires a physical fix — either reseating a cable or replacing a control board. A reset will not clear a hardware communication fault.
When to stop immediately?
Stop if you notice: Interior temperatures are rising above safe thresholds despite the compressor appearing to run., The display is completely dead and you cannot confirm the current temperatures inside..
Symptoms You May Notice
Display panel goes blank or shows garbled characters
Without reliable communication between the main PCB and the display board, the user interface may freeze, show random symbols, or go completely dark while the appliance continues to run in a default state.
Settings changes are not saved or acknowledged
Pressing temperature up/down or mode buttons produces no response or the change does not take effect, because the display board cannot communicate the command to the main board.
Appliance reverts to default settings after each restart
Because the boards cannot synchronise, user-set temperatures and modes are lost on every power cycle and the unit defaults to its factory settings.
E8 displayed (when the screen is functional)
The control panel shows E8 to indicate an active communication bus fault between control boards.
Possible Causes
Loose or damaged inter-board ribbon cable or connector
The flat ribbon cable or multi-pin connector linking the main PCB and display or secondary board has come loose, been pinched, or has corroded contacts.
DIY PossiblePower surge corrupting board firmware
A voltage spike on the mains can corrupt the communication firmware on one of the boards, causing it to stop responding on the data bus.
Requires ProfessionalFailed main or display control board
One of the communicating boards has developed a hardware fault on its communication circuit, requiring board replacement.
Requires ProfessionalSafe Checks You Can Do
-
1
Power-cycle and wait 10 minutes
Unplug the refrigerator from the wall for a full 10 minutes to allow all capacitors on the PCBs to discharge completely. Restore power and observe whether E8 clears.
A firmware-level communication glitch caused by a brief power interruption often clears with a full discharge cycle.
-
2
Check the supply voltage and power strip
Ensure the fridge is plugged directly into a wall outlet, not through an extension lead or power strip. Confirm the outlet delivers stable voltage using a voltmeter or by plugging in another appliance.
Asko refrigerators require a dedicated 10A circuit for stable operation.
-
3
Inspect inter-board connectors (if accessible)
If your model allows access to the control board area (usually behind the top rear panel), with the unit unplugged, inspect the ribbon cable or multi-pin connector linking the display board to the main PCB. Press connectors firmly home and check for obvious damage.
Take a photo before disconnecting any connectors so you can reconnect in the correct orientation.
Tools required
When to Call a Professional
Contact a qualified technician if:
- A full 10-minute power-cycle and connector inspection do not clear E8 — a control board needs replacement (from $200 for display board, from $280 for main PCB).
- The ribbon cable between boards is visibly damaged, torn, or has corroded contacts.
- E8 appeared immediately after a lightning strike or power outage — a surge protector failure may have damaged both boards simultaneously.
