• Check that the circuit breaker for your oven/range (typically 40-50 amp double-pole breaker) is in the ON position; if tripped, switch it fully OFF then back ON
• Ensure the oven door is completely closed and latched properly
• Allow the oven to cool for at least 30 minutes before attempting any troubleshooting
• Verify there is at least 4-6 inches of clearance on all sides of the appliance for proper ventilation
• Check that nothing is blocking the cooling vents on the back or sides of the unit
• Confirm the control panel settings are not locked and all buttons respond to touch
• Perform a hard reset: Turn OFF the main circuit breaker for 60 seconds, then turn it back ON
• Wait 2-3 minutes for the appliance to complete its startup sequence and check if error clears
• Do NOT attempt to open the oven cavity or disassemble any components
• If error persists after reset, contact a certified Miele service technician for professional diagnosis and repair
