Safety Checks You Can Do

    • Turn off the oven and locate your home's circuit breaker panel; switch off the breaker controlling the Asko oven for 60 seconds, then switch it back on to reset the appliance • Check that your oven is properly plugged in and receiving power (verify indicator lights illuminate when powered on) • Ensure the oven door closes completely and latches securely, as a loose door can trigger sensor errors • Review your oven's control panel settings and verify no unusual modes are activated that might disable heating functions • Allow the oven to cool completely for at least 30 minutes before attempting to use it again • Check your home's circuit breaker to confirm the 240V dedicated oven circuit has not tripped; reset if necessary • Verify no other high-wattage appliances are running simultaneously on the same electrical circuit, as this can reduce available voltage to the oven • Inspect the oven's exterior vents and cooling fan area to ensure they are not blocked by dust or debris • If the error clears after the reset but returns frequently, contact on 844-731-2978 for Asko service technician in the USA for professional diagnosis and repair
