Error Code Explained
What Does the Wolf F3 Error Code Mean?
F3 on a Wolf Convection Steam Oven indicates the oven temperature sensor circuit is open — the probe has broken internally or its connector is disconnected. The ERC shuts down oven heating when it cannot obtain a valid temperature reading. The steam environment adds complexity — moisture can accelerate sensor probe corrosion over time.
