Asko range hood SWITCH-FAIL error is a common issue reported by Asko appliance owners.

Answer to continue safely
Is it safe to keep using?
Maybe. If the fan still runs at at least one speed, the hood can be used at that speed while awaiting repair. A completely unresponsive panel means the hood cannot be operated safely.
Can I reset the code?
Yes. A 30-second power-cycle at the breaker can reset a locked or confused control board. If the fault returns or does not clear, a hardware repair is needed.
When to stop immediately?
Stop if you notice: Entire control panel is unresponsive — hood cannot be used safely., Sparking or burning smell from the panel area when buttons are pressed..
Symptoms You May Notice
Speed buttons do not respond
Pressing speed-selection buttons produces no change in fan speed; the panel gives no tactile or audible feedback.
Hood stuck on one speed
Fan runs at a fixed speed and cannot be changed up or down, suggesting a partial control board fault.
Touch panel intermittently unresponsive
Panel works sometimes but not others, often correlating with humidity or temperature near the hob.
Wrong speed activated when a button is pressed
A speed other than the one selected activates, indicating a short circuit on the touch panel or PCB.
Possible Causes
Grease or moisture on touch panel
Capacitive touch panels are sensitive to contamination; grease films prevent proper touch registration.
DIY PossibleFailed push-button or touch switch
Mechanical buttons wear out with repeated use; touch sensors can fail due to grease ingress over time.
Requires ProfessionalControl board speed-control fault
The triac or relay controlling each motor speed can fail individually, leaving other speeds operational.
Requires ProfessionalSafe Checks You Can Do
-
1
Clean the touch panel
With the hood switched off, wipe the entire control panel surface with a clean, dry microfibre cloth. Pay extra attention to the edges of each button zone.
Do not use wet cloths or sprays on the panel — moisture is as disruptive to touch panels as grease.
-
2
Power-cycle the hood
Switch off at the circuit breaker for 30 seconds, then restore power. Test each button from lowest to highest speed.
Some Asko models have a control lock feature — check if the child lock icon is illuminated and hold the lock button for 3 seconds to disable.

3
Document which buttons are affected
Test every button and note exactly which ones respond and which do not. A partial failure (e.g., only high speed fails) helps narrow the fault to a specific component.
Take a short video to show the technician — this can reduce diagnosis time and cost.
When to Call a Professional
Contact a qualified technician if:
- Panel remains unresponsive after thorough cleaning and power-cycling.
- Multiple speed settings fail, pointing to a control board rather than a single switch.
- Physical damage (cracked panel, burned button) is visible on the control surface.
