• Verify your home circuit breaker has not tripped; check the breaker dedicated to your Miele oven range and reset if needed
• Ensure the oven door is fully closed and latches securely with an audible click
• Turn off all oven and range controls and verify settings are at neutral or OFF positions
• Allow the appliance to cool completely for at least 30 minutes before attempting to use it again
• Check that adequate ventilation space (minimum 4 inches) exists on all sides and top of the oven range; ensure no objects are blocking vents
• Perform a hard reset by switching off the dedicated circuit breaker for the oven range for exactly 60 seconds, then switch back on
• Visually inspect the oven door seals for damage or gaps that could affect cooking temperature accuracy
• Wait 5 minutes after power restoration for the control system to fully reinitialize before attempting to use oven
• If error persists after reset, note the exact error code display and do not attempt further operation
