• Check your home's main circuit breaker panel to ensure the breaker for your oven/range is in the ON position; if tripped, switch it fully OFF then back ON
• Ensure the oven door is completely closed and latches firmly with an audible click
• Review the control panel settings to confirm no child lock, demo mode, or restricted cooking modes are accidentally enabled
• Allow the appliance to cool for 15-20 minutes, then attempt to power it back on
• Verify adequate ventilation space around your oven and range (minimum 3 inches on sides and back); ensure no objects are blocking vents
• Perform a complete reset by turning off the circuit breaker dedicated to your oven/range for 60 seconds, then turn it back ON to clear temporary software errors
• If error persists after reset, do not attempt further repairs and contact a Miele-authorized service technician or call Miele USA customer support
