Miele Oven & Range Error Code F23

• Oven will not heat or maintains incorrect temperature during cooking
• Error code F23 displays on the control panel
• Oven cycles on and off unexpectedly
• Cooking times are significantly longer than normal
• Food cooks unevenly or remains undercooked
• Control panel may become unresponsive
• Audible beeping or alarm sounds from the appliance

• Faulty temperature sensor (RTD probe) in the oven cavity
• Loose or corroded electrical connections to the temperature sensor
• Damaged wiring harness connecting sensor to control board
• Malfunctioning electronic control board unable to read sensor signals
• Temperature sensor wire short circuit due to heat exposure or wear
• 240V/120V power supply fluctuations affecting sensor readings
• Moisture or condensation inside sensor connector
• Manufacturing defect in the temperature sensing element

• Turn off the circuit breaker supplying power to your Miele oven for 60 seconds, then switch it back on to perform a complete system reset
• Verify the oven door closes completely and latches securely, as a partially open door can trigger sensor errors
• Check your home's circuit breaker panel to ensure the breaker for the oven is in the ON position and has not tripped
• Ensure adequate ventilation around and behind the oven, allowing at least 2 inches of clearance from walls
• Allow the oven to cool completely (at least 30 minutes) before attempting to use it again
• Review the control panel display to confirm F23 is the only error code showing
• Unplug any external electrical devices plugged into outlets near the oven that may cause power interference
• Check that the oven is receiving proper electrical power by testing outlet voltage with a multimeter if available
• Consult your Miele user manual to confirm F23 error code meaning for your specific USA model number
• Contact Miele customer service or a certified technician if error persists after reset, as internal component replacement may be required
