Asko Dishwasher F11 Error: Control board comm fault
Asko dishwasher F11 error is a common issue reported by Asko appliance owners. What Does Error Code F11 Mean on an Asko Dishwasher? Error code F11 on Asko dishwashers — including models in the D5000, D5100, and DBI665 range — signals an internal communication fault between the main control board and another electronic module.

Answer to continue safely
Is it safe to keep using?
No. F11 prevents the machine from operating at all. Do not attempt to force-start cycles or bypass the fault — if a board has failed, continued attempts to start will not succeed and may cause further damage.
Can I reset the code?
Yes. A 5-minute hard power reset can clear F11 if it was caused by a temporary communication glitch or power disturbance. A failed PCB will cause F11 to return immediately on every power-up.
When to stop immediately?
Stop if you notice: F11 appears immediately on every power-up even after a full 5-minute reset, The display shows no characters at all or flashes continuously without displaying anything readable.
Symptoms You May Notice
Dishwasher becomes completely unresponsive after displaying F11
All buttons stop responding, the display freezes or shows F11 without accepting input, and the cycle cannot be started, cancelled, or changed.
Machine stops suddenly mid-cycle and cannot be restarted
The cycle halts without completing any phase, and restarting the machine results in F11 appearing again within seconds of pressing Start.
Display shows scrambled characters or partial segments alongside F11
The display board itself may be failing, producing garbled characters, missing segments, or erratic backlight behaviour in addition to the F11 fault code.
F11 appears immediately on power-up before any cycle is selected
The communication fault is detected at boot-time before any user input, confirming an electronic board issue rather than a mechanical problem triggered by a running cycle.
Possible Causes
Loose inter-board wiring harness connector
A ribbon cable or plug connector linking the main board to the display board or motor driver has vibrated loose, interrupting the communication signal.
DIY PossiblePower supply disturbance causing board reset
A voltage spike, brownout, or lightning strike has disrupted the communication bus, causing one board to reset out of sync with the others.
DIY PossibleFailed control board or display board
One of the PCBs has sustained damage from a component failure, water ingress, or age-related deterioration, and must be replaced to restore communication.
Requires ProfessionalSafe Checks You Can Do
-
1
Perform a full hard power reset
Switch the dishwasher off at the power button. Pull the mains plug from the wall socket (or switch off the circuit breaker). Wait exactly 5 minutes — this is longer than a standard reset and allows all board capacitors to fully discharge. Reconnect power and turn the machine on. Do not press any other buttons for 30 seconds to allow the boards to complete their boot sequence.
If the machine is on a switched fused spur, use the spur switch rather than unplugging to avoid repeatedly handling the plug.

2
Connect directly to a wall outlet
If the dishwasher is plugged into an extension lead or power strip, move the plug to a direct wall socket. Check that the socket is on a dedicated 13A or 15A circuit without other high-load appliances. Loose connections in extension leads cause voltage fluctuations that trigger F11.
Asko dishwashers should always be connected to a direct, dedicated wall outlet — not a shared extension.

3
Attempt a factory reset if supported
Refer to your Asko model manual for the factory reset procedure — on many D5000 series models this involves pressing and holding Start while powering on. A factory reset clears stored fault codes and resets communication parameters without erasing wash program settings.
The factory reset sequence varies between D5000 and DBI series models — always check the model-specific manual rather than using a generic procedure.
When to Call a Professional
Contact a qualified technician if:
- F11 returns within seconds of every power-up after multiple hard resets
- Visual inspection inside the door panel reveals a burned or discoloured PCB component
- A replacement display board does not clear F11, indicating the main control board is the faulty component
