Error Code Explained
What Does the Wolf E8 Error Code Mean?
E8 on a Wolf M Series Speed Oven indicates the cavity temperature sensor — used to monitor internal oven temperature during convection and speed-cook operation — has failed or is reading outside the acceptable range. Convection and speed-cook modes that depend on temperature feedback will be affected.
