Error Code Explained

What Does the Wolf F8 Error Code Mean?

F8 on a Wolf wall oven indicates a fault in the relay board or broil element relay circuit. On Wolf M Series and E Series wall ovens, a relay board controls high-current heating elements. F8 signals the ERC has detected an unexpected open or fault in this relay circuit. The broil function is typically unavailable while F8 is active.

Root Causes

Common Causes of the Wolf F8 Error Code

  • 1
    Failed Relay on Relay Board
    The broil relay on the relay board has failed, preventing normal ERC control of the broil element.
  • 2
    Shorted Broil Element
    The broil element has failed with a short circuit, causing overcurrent detection in the relay circuit.
  • 3
    Wiring Fault Between ERC and Relay Board
    An open or shorted wiring harness between the ERC and relay board creates F8 without actual board failure.
