ER22 indicates a temperature sensor malfunction or thermal protection activation on your Asko cooktop. This error prevents the cooktop from operating normally to protect against overheating or electrical safety issues.
• Cooktop will not heat or ignite burners
• Error code ER22 displays on the control panel
• Specific burner(s) may be unresponsive while others function normally
• Cooktop shuts off unexpectedly during cooking
• Burner ignition clicks repeatedly without igniting
• Control panel becomes unresponsive to touch inputs
🔧
Possible Causes
• Temperature sensor failure or disconnection in one or more burner circuits
• Thermal overload protection triggered due to sustained high heat
• Faulty wiring connection between burner and control module
• Moisture or debris on burner ignition components
• Damaged burner cap or grate causing improper heat distribution
• Malfunctioning control board unable to read temperature data from 120V/240V circuitry
• Power supply voltage fluctuation or insufficient circuit capacity (common with 240V cooktop circuits)
• Cookware left unattended causing excessive surface temperature buildup
✅
Safety Checks You Can Do
• Turn off the cooktop and allow it to cool completely for at least 30 minutes
• Check your home's circuit breaker panel to ensure the cooktop circuit breaker (typically 40-50 amp for 240V models) is in the ON position; if it has tripped, flip it OFF then back ON
• Inspect the cooktop surface for any standing water, spills, or debris; clean thoroughly with a dry cloth
• Verify all burner caps are properly seated and grates are correctly positioned
• For induction models, confirm cookware has a ferromagnetic bottom (test with a magnet) and is compatible with induction cooking
• Review the control panel settings to ensure no child lock or special cooking modes are activated
• Unplug the cooktop or switch off the dedicated circuit breaker for 60 seconds, then restore power to reset the appliance
• Wait 5 minutes after reset before attempting to use the cooktop again
• Test one burner at a time to determine if error recurs consistently or sporadically
• If error persists after these steps, contact a certified Asko service technician or your retailer for professional diagnostics
